Waterfowl Festival History:

  The Waterfowl Festival was founded in 1971 by a group of Eastern Shore sportsmen and women looking to share the unique heritage of the area while raising funds to protect the wildlife and habitat what were integral to the region’s way of life. Starting with 50 exhibitors and 4,000 visitors, the first Festival turned a profit of $7,500, which was contributed to Ducks Unlimited.

Waterfowl Festival Purpose:

  Conservation The Waterfowl Festival contributes the proceeds of each annual event to Waterfowl Chesapeake – the Festival’s sister organization that focuses exclusively on supporting conservation work around the Chesapeake Bay watershed. Founded in 2011, Waterfowl Chesapeake builds on the conservation tradition of the Waterfowl Festival, which has granted more than $5 million to over fifty national and regional conservation organizations and their projects. Promotion of Wildlife Art The Festival provides an environment for artisans to gather, exhibit and sell their work. More than 300 nationally recognized artists are invited to participate, exhibiting paintings, sculpture, carvings, photography, decoys, crafts and folk art. The public is provided with the opportunity to view and purchase the finest wildlife art available in the world. A Showcase for the Eastern Shore of Maryland Autumn is the most spectacular time of year for the Eastern Shore and the Waterfowl Festival in historic Easton shows it off at its best. Thousands of geese fly overhead while thousands of visitors stroll the streets. Local hunting traditions and sportsmen's goods and gear are highlighted in addition to the wildlife art, with the World Championship Goose Calling Contest®, the Mason-Dixon Regional Duck Calling Contest and Delmarva Dock Dogs® Competition taking place as well as retriever demonstrations, wine tasting pavilion, kids activities and much more.

Who Attends Waterfowl Festival:

  18,000 to 20,000 visitors from throughout the U.S. and other countries attend each year. Art collectors looking for the best in wildlife art, hunting enthusiasts celebrating their traditions and skills, families looking for a weekend getaway, and shoppers seeking the perfect holiday gifts all find something to enjoy at the Waterfowl Festival. Who Makes It Happen: More than 1,500 volunteers offer their time and services to stage each year's Festival. More than 60 committees work year-round to organize the events at 12 exhibit locations throughout the town of Easton. A small staff and an eighteen-member volunteer Board of Directors coordinate these efforts.

Chesapeake Bay Waterfowl - Wood Ducks

Wood Ducks: A Pictorial Study
Wood ducks add color to Bay's forested shorelines
Bay Naturalist / By Kathy Reshetiloff - Bay Journal

When it comes to Chesapeake Bay waterfowl, most people are familiar with commonly seen wintering birds like Canada geese. Those who frequent areas of open water and marshes of the Bay, might also see canvasbacks, buffleheads, black ducks and tundra swans. Explore the Bay's forested shorelines and its many tributaries during warmer months, though, and you might encounter one of the most beautiful ducks in North America, the wood duck.

The wood duck's beauty is even reflected in its scientific name, Aix sponsa. From the Greek word aiks for water bird and Latin word sponsa for betrothed, the name refers to plumage so striking that the wood duck looks like it is dressed for a wedding.

While wintering waterfowl are breeding on the tundra and prairies, wood ducks are breeding in the Chesapeake Bay watershed. Early colonists aptly called the woody the "summer duck." They have also been known as the Carolina duck, because of where it was first described, the swamp duck, because of its preferred habitat, and the acorn duck after one of its favorite foods.

Birds Need All The Help We Can Offer

Bird Migration and Global Change
Migration’s tough enough, birds need all the help we can offer
Bay Naturalist / By Kathy Reshetiloff - Bay Journal

There once was a time when I could not quite understand birdwatchers. What did these people get from watching tiny blurs of color flitting through trees? Don’t get me wrong, I have always liked birds, always had bird feeders in my yard. But I never really understood the fascination with birds. In the past few years, however, I too have become captivated with these fascinating creatures.

Birds are the nomads of the animal world, ceaselessly traveling with the change in seasons. It must be the burden they carry for the gift of flight.

While some birds remain in one area throughout the year, most are condemned to constantly follow their food source.

In the fall, as the climate gets cooler, birds who feed exclusively on insects, fruit or pollen must migrate to the more temperate climates of South and Central America, Mexico and the Caribbean.

As spring returns to North America, so do the birds — following their food sources — back to their breeding grounds.

More than 360 species of birds make this annual migration including songbirds (warblers, thrushes, tanagers and vireos), shorebirds (sandpipers, plovers and terns), some raptors (hawks, kites and vultures), and a few waterfowl (teal).

Some of these birds are common —the American robin, Eastern bluebird, ruby-throated hummingbird, gray catbird, purple martin, barn swallow and chimney swift. Others, such as the red-eyed vireo, scarlet tanager, wood thrush and Cape May warbler, may be familiar only to bird watchers.

The importance of migratory birds cannot be overlooked. Birds are our best natural insect control, eating tons of bugs annually.

As green leaves emerge each spring, so do millions of caterpillars and insects. Coinciding with this event, an array of birds, like orioles, vireos, flycatchers, warblers and swallows, return to North America and feast upon the abundant insects.

Birds are important economically, too. Americans devote a great deal of time and money to bird watching. According to the 1996 National Survey of Fishing Hunting, and Wildlife-associated Recreation, almost 63 million Americans participated in wildlife watching activities. Seventy-five percent of wildlife watchers traveled to see birds. At home, 96 percent of the respondents were bird watching.

All of these activities generate money through sales and services such as travel, lodging and meals. Americans spent $29 billion on wildlife watching activities. Of that, $17 billion was spent on equipment, $9 billion on trip-related expenses and $3 billion on other items.

But their importance to our environment and economy, has not prevented many bird species from declining.This is due to the loss of their habitats as large tracts of fields, forests and wetlands are disappearing for development.

Today, many birds must nest in smaller, fragmented habitats. This leaves eggs and chicks vulnerable to predation by other birds, such as blue jays and crows, and mammals, such as raccoons and cats.

Fewer chicks survive to replace adults killed by natural causes, such as surviving the perilous winter and spring migrations between North and Central or South America.

Although public lands like refuges and parks are extremely important to migrating birds, they alone cannot provide the habitat that birds need.

Nationwide, 71 percent of the land is privately owned. Private land is almost equally divided between range, forest, crops, pasture and other land uses.

Private landowners can restore, enhance or protect habitats beneficial to birds and other wildlife while still keeping their current use.

State and federal wildlife agencies have many programs to assist landowners with habitat enhancement projects.

Contact your state wildlife agency or the U.S. Fish and Wildlife Service’s Partners for Fish and Wildlife program for information about habitat for birds and other wildlife.
People who don’t own large areas of land can still help:
  • Create Backyard Habitat: By planting native vegetation, homeowners can provide badly needed food and cover for birds and other wildlife. Plant a variety of trees, shrubs and plants and remember to provide a source of water.
  • Try Shade-Grown Coffee: Wintering habitats in Central and South America are also being altered. If you’re a coffee lover, consider buying shade-grown coffee. Coffee grown on clear-cut plantations destroys critical wintering habitat for migratory birds.
  • Keep Cats Indoors: There are at least 68 million pet cats in the United States. Birds make up 20–30 percent of outdoor cats’ prey. Cat owners can reduce the number of birds maimed and killed simply by keeping their cats indoors.
  • Reduce Chemical Use: Pesticides are often harmful for birds. While pesticides are intended to control specific pests, some harm or kill non-target species. Contact your state university’s cooperative extension service for more information about low impact solutions to pest problems.

Sex Life of Plants

Sex life of plants is all about the birds & bees (bats too!)
Bay Naturalist / By Kathy Reshetiloff - Bay Journal

Imagine the world without natural fibers, fruits, vegetables or flowers. That’s what it would be like without the insects and other animals that pollinate our plants.

Two-thirds of our flowering plants are pollinated by insects, birds or bats; and more than three-fourths of the world’s crops rely on insects and other animals for pollination. The global economic benefit of pollination has been estimated at $117 billion. Pollination is critical to successful orchards, field crops, forage crops, home gardens, endangered species and ecological restoration.

As food producers and consumers, we all need to be aware of the importance of pollinators to plants and our environment. Most plants need to make seeds to reproduce. But many can’t do it by themselves. To make seeds, the female part of the plant, the pistil, needs pollen from the male part of the flower, the stamen.

In addition, cross-pollination is the rule of thumb in the plant world. Pollen from the stamen of one flower must be transported to the pistil of another so that the plant can make seeds and reproduce. Some plants rely on the wind to do this. Many others depend on animals to move pollen from one flower to another.

Insects, such as bees, get sticky pollen grains on their bodies while gathering nectar from flowers. As they move from one flower to another, bees transfer pollen to the pistils.

Bees aren’t the only pollinators, though. Other insects, such as wasps, flies, butterflies, moths and beetles are important pollinators. Larger animals, such as birds (especially hummingbirds), flying foxes, bats, opossums, lemurs, rodents and even a gecko, help to move pollen.

Plants need pollinators and vice versa. This co-dependence is exhibited in many ways. Many night-pollinated flowers close during the day, to prevent thieves from getting at their nectar and pollen. Many daytime-pollinated flowers close at night for the same reason. Flowers pollinated at night are usually white or pale yellow and very fragrant. This helps to announce the flowers’ presence. Darker-colored flowers, not as visible at night, are usually pollinated by day-flying insects.

Flowers also assist the pollinator in finding where the pollen or nectar is stored. Flowers often have bee lines — dots or color variations — that direct the pollinator.

Flowers come in many shapes: bowl, cup, star or tube. Shapes are specific to pollinators and, in some cases, also keep out unwanted pollen collectors. Some insects, like ants, love nectar, but are not good pollinators. Plants have developed protective devices, like closed throats or sticky hairs, that are designed to keep ants and other robbers out.

Other plants exude a sweet liquid on their stem to sidetrack unwanted visitors. Hiding nectar in tubes and closed blossoms has many advantages. If the nectar is hard to get at, usually only designated pollinators can find it.

Despite their importance to our economy and our lives, many pollinators are in trouble. Honeybees, raised specifically to pollinate crops, are in decline. One quarter of all managed hives have been lost since 1990, mainly because of parasitic mites, disease, pesticide poisoning and climate fluctuations. Wild pollinators are also disappearing at alarming rates, the result of habitat loss, pesticide poisoning, diseases and pests.

A healthy ecosystem provides pollinators with habitat for foraging, nesting, roosting and mating. Houses, businesses and roads are replacing the native fields, wetlands and forests that are home to many pollinators. In addition, many of the wildflowers that they feed on are rapidly disappearing.

Many of the pesticides used on farms and backyard gardens are broad-spectrum varieties that are not only toxic for plant pests but beneficial insects as well.

Pollinators such as bats, butterflies and hummingbirds face even more problems. They may migrate many miles over the course of a year and need nectar-producing flowers all along their journey. As wildflowers and natural habitats are being replaced by development, less food and habitat are available along the migration route. Migrating pollinators also have to deal with such threats as automobiles and pesticides.

There are many things each of us can do to help pollinators. Reduce the use of pesticides or, if possible, stop using them altogether. If you must use an insecticide, apply it in the evening, when many pollinators are inactive.

Restore or enhance wildlife habitat on your land by planting gardens filled with nectar-producing flowers that are native to your area.

Provide nesting sites for birds, bats, butterflies, bees and other insects. Leave tree stumps, dead branches and rotting trees on your property, if possible, as they provide nesting sites for some species of bees. If you find a bee nest too close to your home, don’t destroy it. Contact a local beekeeper or your state cooperative extension service for advice on how to remove the nest without harming the bees.

Chesapeake Bay - Glimpses of Bay's Past Reveal Paradise Lost

Chesapeake: Exploring the Water Trail of Captain John Smith
History Lessons for the Future
Glimpses of Bay's Past Reveal Paradise Lost
Past is Prologue / By Dr. Kent Mountford - Bay Journal

"A faire Bay, compassed but at the mouth with fruitfull and delightsome land." - Capt. John Smith in his 1607 description of the Chesapeake Bay

The Discovery

In latitude 36 degrees north, the ships "Susan Constant," "Godspeed" and the pinnace, "Discovery," were several weeks at sea from the Caribbean. Fresh food was long gone; drinking water was stale in its casks. Bound for the Chesapeake, in the raw cold of an Atlantic spring, they had sailed three days beyond their reckoning and found no land.

Captain Ratcliffe on the "Discovery" voted to return to England. But that night, a storm set upon them and, as Thomas Studley wrote:

"God the guider of all good actions ... did drive them by his providence to their desired port, beyond all their expectations; for never any of them had seen that coast."

This was Virginia, the land they were to colonize for England.

The ships were brought to anchor "at the mouth of a very goodly bay, 18 or 20 miles broad. The cape on the south is called Cape Henry, in honour of our of our most noble Prince. The land, white hilly sands ... and all along the shores great plenty of pines and firs."

Dimly visible to the north was what they named Cape Charles. From there, the Chesapeake's Eastern Shore stretched about 200 miles. Beyond that, the vast watershed spread inland to mountains not yet seen. In all, it drained 64,000 square miles, and had been almost completely covered with a largely unbroken forest since the end of the ice age 10,000 years before.

This remarkable forest was stingy with its nutrients, allowing little nitrogen or phosphorus (the two chemicals most responsible for spurring the modern Bay's massive algae blooms) and sediment to escape. Count Zinzindorf, a traveling companion of explorer and botanist William Bartram in 1742 along the North Branch Susquehanna's thickly forested shores, described "beautifully transparent" water, so clear that swimming chin deep, they "might have seen a pin at the bottom."

In the words of these early explorers and settlers there is a Chesapeake not always recognized today - a Bay filled with grasses, oysters and canvasbacks, a watershed with elk and bison.

The Land

After weeks at sea, the Englishmen were drawn ashore by the scent of land and the promise of new spring vegetation. They rowed into what is today called Lynnhaven Inlet and explored Long Creek and Broad Bay. John Smith later recorded: "cypress near three fadome about at the foot (18 feet circumference), very straight and 50, 60, or 80 foot without a branch..." As late as the 18th century, visitors would find tulip poplars 20 feet around and 90 feet high.

John Smith also spoke of oak trees on the uplands that yielded timber: "two foote and a half square ... for 20 yards long." These were trees that had never seen a steel ax; a forest which had grown and matured into tall colonnades with straight trunks and a high canopy which shaded the primeval forest floor in a perpetual deep twilight. These trees grew so slowly that, in some years, they would add only 2 millimeters to their diameter. Such trees, hundreds of years old, could never be replaced yet the temptation to harvest them would be universal.

West, beyond the coastal plain of the piedmont, above the rocky fall lines of the Bay's rivers, lay a much more tangled forest than along the Bay. Colonist Anthony Bagnall said his Wighcocomoco Indian friend Mosco knew nothing of the land beyond the mountains "because the woods were not burnt" (to clear the understory) and this trackless forest was traveled with difficulty. To colonists, who were used to England's orderly fields and coppiced woodlands, the forest and its dampness were unhealthy and dark. It must have been daunting to a settler armed only with an ax.

While the great forest system seemed inexhaustible to Native American and European alike, game could be locally overharvested with primitive weapons. There was more game in the interior and parties would venture there, often at the risk of encountering hostile, inland tribes.

John Smith reported that intensive game drives could yield: "6, 8, 10 or 15 (whitetail deer) at a hunting".

At the same time, Smith accused the Native Americans of overhunting game on the partly landlocked river necks of Maryland and Virginia. His contemporary John Pory wrote that deer, turtles "and other Beasts and fowls will exceedingly increase" if the Indians were pushed out of the country for they hunted regardless of season and did not spare "Male nor Female, old nor young, egges nor birds, fat nor lean..."

Cyprian Thorogood, who came over with Lord Baltimore's colonists on the "Ark" and "Dove," voyaged to the head of the Bay in mid-April 1634, 26 years after Smith's exploration. His boat passed Poole's Island, where he determined the fresh water in the Bay began. He navigated up what is today the Elk River and observed "many deere, yelkes (elk) and turkies, but caught none."

Eastern woodland bison still roamed the hinterlands, inspiring the names for Virginia's Cow and Calf Pasture rivers. The animals were not inexhaustible, though. The last woodland bison was reportedly tracked in heavy snow and shot Jan. 1, 1800, after having foraged, unwelcome, around a farmer's barn. Wild elk, quickly shot out of Maryland, lingered longer along the Susquehanna, where in the 1730s, some elk had been tamed and came and went with farmers' cattle.

Insects were as much a feature of the colonial Chesapeake as today. Naturalist and explorer John White accurately drew a swallowtail butterfly in 1585. Colonists wondered at the emergence of the summer cicadas and their great noise in the forest. Insects were pests too, both the natives such as the salt marsh green head fly, and those species that arrived with the Europeans, such as the black stable fly, a plague of today's summer and autumn Chesapeake.

It's astounding to most of us, but the honeybee, so much a part of our cooking, agriculture and lore, was introduced by Europeans. The Native Americans called it the "white man's fly."

Up the Susquehanna, a Moravian missionary wrote:

"Muschgetters (mosquitoes) tormented us all night." John Smith was inaccurate in saying: "nor (are) their flies ... (in) any way pernicious, where in the south parts of America they are always pernicious, and often deadly," unaware that the Chesapeake marshlands permitted the spread of malarial fevers.

The Natives

But was this wonderful land really pristine, free from human disturbance? Native Americans had arrived 6,000 to 9,000 years earlier, as nomadic hunter-gatherers, and had developed a lifestyle that blended hunting, fishing and agriculture for more than 1,000 years before the Virginia colony was "planted."

How many Native Americans were here before the Europeans? Smith estimated that about 5,000 natives lived within 60 miles of Jamestown. Others suggest there were 30,000 people around the Bay's perimeter, and in the entire basin, perhaps only 100,000. Today, about 15 million people fill the Bay's watershed.

Though this land seemed untouched to the colonists, the Native Americans routinely set fires to drive game out of the woodlands and thus shaped forest ecology by thinning undergrowth, which ensured the growth of larger trees. That, coupled with the gathering of firewood from the forest floor, resulted in the woods being so open that a horse could be ridden anywhere, or even a coach driven without impediment, on the necks of land between the tidewater rivers of what would become Maryland and Virginia.

Native Americans seasonally congregated in villages on coastal plains bordering the Bay and rivers where they planted ecologically sensible crops of beans (which fix the fertilizer nitrogen from air), corn (a nitrogen user that also provides a natural trellis for the beans), squashes (which create a living mulch and groundcover against dehydration) and native tobacco. These fertile, floodplain soils would soon become prime agricultural land for the colonists' plantations.

The native tobacco, though, was not the plant that would become Virginia's "gold," but a harsh-smoking strain that was even too strong for northern Native American tribes like the Iroquois, to whom it was later offered - unsuccessfully - as trade goods. John Rolfe, who married Powhatan's daughter Pocahontas, later introduced a Central/South American strain called "Orinoco," with which the English colonists pursued their fortunes.

In the centuries before Europeans arrived, as soils became less productive, the Native Americans would burn or girdle the trees in an adjacent area, which killed them and allowed sunlight to reach the forest floor.

In spring, they would plant their crops in the rich and moist topsoils. These topsoils had accumulated on the forest floor - at an estimated rate of only an inch every 600 years - to a depth that one colonist reported as 12 inches in 1634.

It was for these substantial parcels of land, cleared of trees and eventually freed of roots and snags, that the Europeans would compete - or less commonly, bargain - with the Native Americans.

This alluvial land was productive. Smith found Powhatan's warehouses bulging with corn that some think was a tribute paid to him as the head of the tribal confederation.

In one of Smith's heavy-handed trading ventures with the Powhatans, 25 pounds of copper and 50 pounds of iron and beads were traded for 479 bushels of Indian corn that was delivered by barge to the Jamestown commissary. Had they been savvier traders that autumn, the colonists might have acquired 350 tons - almost 13,000 bushels - enough to feed 240 colonists for a year.

Bounty from the Bay

Just as the soils of its watershed were rich, so was the Bay itself. Smith and others made long lists and descriptions of fish familiar and foreign to English eyes. Smith talked about the Chesapeake's "fifth river... Pawtuxunt ... Here are infinite skulls (schools) of diverse kinds of fish more than elsewhere."

Still, some modern readers scoff at his observation: "and in diverse places that abundance of fish, lying so thick with their heads above the water, as for want of nets (our barge driving amongst them) we attempted to catch them with a frying pan: but we found it a bad instrument to catch fish with."

But for the English colonists, feeding themselves was a serious business and they actively fished the tremendous migrations of shad, herring and sturgeon that pulsed into the Bay each spring. Long before European intervention, Native Americans funneled these migratory fishes into baskets positioned at the juncture of a "vee" formed by stone weirs hand-built across the river channel. Some of these can still be seen in our nontidal rivers hundreds of years later.

Migratory fish went upstream past what would become the New York border and westward into the Appalachians. William Cooper, founder of Cooperstown and father of novelist James Fennimore Cooper, was an 18th century settler on Lake Otsego, the source of the Susquehanna. He reported on the harsh winter of 1789, during which the fledgling settlement of Cooperstown nearly starved:

"A singular event seemed sent by a good Providence to our relief; it was reported to me that unusual shoals of fish were seen moving in the clear water of the Susquehanna. I went and was surprised to find that they were herrings. We made something like a small net by the interweaving of twigs, and by this rude contrivance, we were able to take them in thousands."

In the 1800s, men who had fished in the previous century still remembered catching more than 1,000 shad per night in the Susquehanna near Wilkes Barre, Pa. But those days ended in the first decades of the century. In 1822, authorities reported: "The spring herring ... formerly visited this lake (Otsego) in immense multitudes for the purpose of spawning; now their ascent is arrested by the erection of dams."

The Indians captured huge, relatively slow-swimming sturgeon by lassoing their tails or wrestling them until the fish tired and could be landed. The colonists used nets of strong cord and Smith reported catching them in abundance during their upstream migration. Their flesh - not caviar - saved many colonists from starvation. Smith commented:

"We had more sturgeon, than could be devoured by dog or man, of which the industrious by drying and pounding, mingled with caviar, sorrel and other wholesome herbs would make bread and good meat; ... we lived very well in regard of such a diet."

Underwater beds of Bay grasses were extensive at the time of European contact, and seeds deep in the sediments indicate they had been a feature of the Chesapeake for thousands of years and probably covered hundreds of thousands of acres along the Bay's shallow margins, down to a maximum depth of 2-3 meters (10 feet). The earliest aerial photographs we have are from 1938 and show immense beds in the Patuxent River, in some places stretching 1,000 feet offshore, where virtually no grasses now grow. Only about 60,000 acres of grasses remain in the Bay today.

In colonial times, these vast underwater meadows offered a wonderful shelter for billions of juvenile fish and crabs. The grasses were foraged by millions of waterfowl, diamondback terrapins and visiting loggerhead sea turtles (which appear to have been the main dish at feasts in Jamestown). As in the last few summers, an occasional wandering manatee - one was recorded in the Rappahannock by Thomas Glover in 1676 - also grazed these grass beds.

Surprisingly few early writers mentioned, or recognized, the value of Bay grasses to the ecosystem, though Smith and three of his companions, wrote that they "spied many fishes lurking in the reeds" - presumably Bay grass beds - while exploring the mouth of the Rappahannock.

These fish were cownose rays, 30 inches across the wingtips, which bottom-feed in June across the Bay's shallows. Each has a serrated spine, slimed with toxic mucus at the base of its tail. John Smith, spearing one massive, flailing ray with his short-sword, was pierced an inch-and-a-half deep in his wrist by this "stinger. The torment was instantly so extreme, that in four hours time had so swollen his hand, arm and shoulder, we (expected) ... his funeral." His body, helped by a "precious oil" administered to the wound by his shipmate Dr. Russell, overcame the anaphylactic shock, and Smith ate some of the ray for supper. This adventure lead to the naming of Stingray Point and (reputedly) Antipoison Creek.

With clear water, grass beds thrived and provided reliable winter food from year to year. Later writers, especially those concerned about waterfowl, recognized the value of the extensive wild celery beds on the Susquehanna Flats for the immense populations of canvasback and redhead ducks.

Tales of waterfowl on the Chesapeake are legion. Native American hunters could barely make a serious harvest of these populations with their bows and arrows. One colonist recorded that the birds "arrive in millionous multitudes." Feeding abundantly on submerged grasses every winter, there was mutual benefit when the birds, upon digestion, returned nutrients to a Bay that was relatively underfertilized when compared with today's eutrophic conditions.

John Smith and two others, hunting from a small boat some distance from Jamestown, brought down 148 waterfowl. Colonist Robert Evelyn, exploring near the head of the Bay in the mid-1600s, saw a flight of ducks and estimated it at a mile across and 7 miles long. The taking to flight by such flocks was amazing. He recorded the "rushing and vibration" as sounding like a storm coming through trees, or like a whirlwind in the case of the geese they startled while canoeing into a small creek.

The clear water that colonists encountered in the Chesapeake Bay was not only husbanded by the basin's massive forests, but it was also maintained by the Bay's extraordinary "reefs" or "rocks" of oysters. In the James and Rappahannock, for example, these oyster reefs or rocks actually broke the surface at low tide, and sailing vessels sometimes grounded unexpectedly upon them.

As late as the Civil War, a crewman aboard the ironclad "USS Monitor," moored in the James, wrote home that they rowed out to the oyster banks daily to gather shellfish for their dinner.

Billions of oysters prospered naturally on grounds covering thousands of acres around the mouths of the Bay's tributaries and at spits or points in the rivers. Here, the ebb and flow of tidal currents swirled a perpetual, living soup of plankton around them. They had only to open their shells to eat, and in the process, they filtered out immense quantities of particulates, clarifying the water. Dr. Roger Newell, of the University of Maryland's Horn Point Environmental Lab, estimated that the Chesapeake's virgin oyster stock had the capacity to filter the entire Bay in several days, a feat that would take today's remnants more than a year to accomplish.

One could wade along many tidal tributary shorelines, as the Native Americans did, and gather abundant, large, rounded "cove" oysters growing on the subtidal sands. But expanding populations, such as those of St. Mary's City - Maryland's Colonial capital - quickly depleted these oyster populations. When Maryland's capitol - and lots of people - moved from St. Mary's to Annapolis in 1694, overharvesting stopped and the cove oysters began to appear again.

The advance warning in this simple observation went unheeded by future generations, and for the next three centuries, the Bay's great oyster resource was mercilessly harvested. The ancient oyster reef structure was dredged away, the meats consumed and the shell carried off for lime burning, road building and, at Solomons Island and Crisfield, filling in the shallows to create new land.

Shell mounds, or middens, characterize the archaeological remains of Native American habitations and demonstrate how dominant oysters were as food. On the lower Potomac's Yeocomico River, archaeologists have documented continuous human habitation reaching back 2,000 years. Middens along the Potomac at Douglas Point indicate that in ancient times, the water was salty enough for oyster growth miles farther upriver than today. Dr. Bob Biggs, a former Bay researcher, believes this was because the vast, ancient forests captured and held more rainfall, and transpired (evaporated into the atmosphere).

Ancient shell deposits, which lie 20 feet or more deep within Chesapeake sediments south of Poole's Island show that perhaps 4,000 years ago, conditions supported prodigious oyster growth much farther up the mainstem Bay than today. These fossil shells are now dredged commercially and thousands of tons are carried down into "the salts" to provide clean surfaces for the larvae of struggling, modern oysters to "strike," or settle, upon and grow.

Impetuous Torrents

Tropical storms have been a feature of the Chesapeake climate since prehistory. And when such storms penetrated into the interior and Appalachians, they caused floods.

In August 1667, there was a great "Hurry-Cane" that destroyed an estimated 10,000 homes in Virginia. Hail, large as turkey eggs, followed by torrential rains ruined two-thirds to four-fifths of the crops. This storm, unprecedented for the 17th century settlers, lasted for 24 hours with the wind beginning in the northeast, backing north and eventually southeast: the typical anticyclonic circulation of tropical storms.

Core samples taken from the floor of the Bay offer a faint picture of storms thousands of years into the past. These cores reveal that ancient and early colonial storms produced only small amounts of sediment compared with storms after deforestation and accelerated development.

The Bay's tributary rivers experience annual freshets, caused by snowmelt and spring rains. John Smith, exploring the James River in 1607, judged by marks on the trees that the river freshets flooded about 8 feet above the base flow level.

But, 78 years after colonization in 1685, the effects of colonization began to be felt and William Byrd I wrote that "a mighty fresh" had come down the James April 26 and 27, causing the river to rise 3 feet higher than ever before, destroying his fences, ruining his tobacco and flooding the first floor of "Belvidere," his house in what is today the heart of Richmond.

Over the next century, English settlers were busy cutting, girdling and burning away the forests for agriculture and timber. Hugh Jones, at the end of the 17th century, said he could not see his neighbors' house for the trees, but speculated that would soon change.

The loss of forest meant increased runoff to the streams and the reduction of evapotranspiration, that immense flow of water up through the billions of trees to the atmosphere. The propensity for flooding and the size of the spring freshets was greatly increased, and as more forest was cut and agriculture expanded onto the piedmont, both runoff and erosion of the land increased further. Dr. Biggs believes that both floods and droughts have increased in severity by 25 percent or more.

The genesis of today's problems in the Bay was in the mid-1700s. Dr. Grace Brush at Johns Hopkins, by studying the Bay's sediments, estimates that by 1760, about 30 percent of the basin's forests had been cut and the layers of sediment deposited on the Bay floor after storms thickened.

Indeed, after a strong freshet, settler Alexander Rose wrote, in 1768: "... the impetuous rains sweep away the whole vegetative Earth from the broken (plowed) grounds (of tidewater) unless they are tended in grain."

Rose's thinking thus anticipated by 230 years the agricultural cover crops that are a hallmark of nutrient management plans on modern Chesapeake farms.

Past as prologue

The words left us by colonists dead for hundreds of years allow us to imagine the extraordinary resources then offered by the Chesapeake. And this is just a sampler from the vast trove of information available.

As obscuring layers are peeled away by historian, archaeologist and natural scientist, more and more of the Chesapeake's past is being revealed.

Since these early colonists, the Bay has been abused for almost four centuries. We have eliminated all but a trace of the peoples who lived here for 9,000 years before us. This vast basin's forests have been removed - often several times over - its rivers have been blocked, its air and waters polluted, its lands incised with centuries of agriculture, allowing so much fertile soil to muddy the Bay. We have inundated the watershed with our locust swarm of population and development.

Yet, there are still substantial remnants of the Bay's great heritage: the autumn flight of geese, a great circle of swimming menhaden, the slash of feeding bluefish, the roil of feeding rockfish. There are the rare, single trees, and even rarer stands of trees that have escaped logging and storms. There is the savor of a Chesapeake oyster, glistening on its half-shell.

Revel in any of these you encounter, and neither despair of making progress against our losses nor become complacent about what remains. All of the Bay's resources are threatened, and they can each vanish if we do not reverse the damages done ... if we do not redouble our efforts to move the Chesapeake toward that dateline of long ago.

Landing

Descendants of cypress recorded by Capt. John Smith can be seen at First Landing State Park near Virginia Beach. Although many cypress grow along the James and Pocomoke rivers, there are only a few, gnarled specimens of very old trees. Only Maryland's "Champion" cypress at Battle Creek, 17 1/2 feet around and 132 feet high remains of the 17th century's great trees. Trees in a virgin forest are not often distinguished by their diameter, but by their height as they strive upward competing for light.

Goodly Pines

There are a few places left where it is still possible to get a sense of what the colonists might have experienced.

Visit a 300-year-old stand of hemlock, 200 miles from the Bay, at Western Maryland's Swallow Falls. Experience the mood of what an ancient forest must have been like: deeply shaded and cool, with morning mist rising from rich moulds and a lush understory. In the summer, temperatures in the forest are 10 degrees Fahrenheit cooler than nearby open country. Some believe that Native Americans never experienced forest temperatures in the 90s.

Of all the streams that Smith and his explorers passed along Maryland's Calvert Cliff shoreline, only uninhabited Parker's Creek, with its otters and eagles, remains somewhat as it might have been in that summer of 1608. This land has been preserved by the American Chestnut Land Trust. Visit Parker's Creek in Port Republic, Md. and join the Trust to protect more wild lands.

Harvesting Corn

Corn is a "New World" crop, unknown in Europe before Columbus' discovery. John Smith's haul of Indian corn was gleaned from many, tiny hand-tilled fields, maybe 3/4 acre per man. By 1609, colonists had planted 30 or 40 acres of their own. By 1614, they had 500 acres and by 1631, with perhaps a 100-bushel-per-acre yield on the best lands, they exported surplus corn. Modern, mechanized farming on Chesapeake soils with hybrid varieties and fertilizer yields 80 to 125 bushels of corn per acre and an average around 110. The U.S. corn crop for 1996 was estimated at a "disappointing" 8.7 billion bushels.

Rays

The cownose ray's serrated spine is slimed with a toxic mucus at the end of the tail, as John Smith painfully discovered. Weighing 20-30 lbs. apiece, these rays are powerful and difficult to land when hooked, but produce substantial and tasty meat from their muscular "wings." They school in thousands up the Bay each spring, when females give live-birth to dinner-plate-size juveniles. The adult females are believed to be pregnant again by the time they leave the Bay in late summer to overwinter off South America. Rays feed on bottom-dwelling clams and worms. Because rays disrupt the bottom while feeding, they're considered destructive to grass beds.

Sora is a squat, chickenlike marsh bird

Sora Rail Colored Old Print Bird Fine Art Plumage C1957
Sora rail-now you see it, most often you don't
On the Wing / By Michael Burke - Bay Journal

The weak winter sun illuminated the reeds on the far side of the shallow pond. The shaded mud flat in the background, though, was what holds my attention.

There's a bird there, but I couldn't make out any details. Feeding with its head down, it ever so slowly emerged into view before slipping behind the plants, and then briefly coming into view again. My mind flipped though the possibilities: a coot or maybe a moorhen?

Just then a group of tourists with energetic youngsters came around the corner, and the bird disappeared into the thick vegetation. At least it didn't flush.

I encouraged my birding companions to wait until the family moved along and pointed out the spot where I saw the elusive bird. Our patience was rewarded minutes later as a sora (Porzana carolina) emerged from the wetland shrubs and shadows into the pale light of the exceptionally warm winter day.

The sora is a squat, chickenlike marsh bird. Weighing 3 ounces, it is slightly smaller than a robin, with a stubby, triangular yellow beak set off with a black face patch that extends down the bird's breast. The black on its chest is edged in gray. The bird cocks its short tail up, revealing a white patch underneath. The rest of the sora is a nondescript combination of browns and blacks.

The sexes look alike, so I don't know if the bird we watched was a male or female.

The sora is part of the rail family (Rallidae). They are notoriously secretive, although the sora is less clandestine than its seldom seen cousins, the yellow and black rails. Even so, the sora is much more often heard than seen. It has a high-pitched, descending call that is often described as a whinny. Because the birds spend most of their lives in dense marsh vegetation, biologists theorize that soras' loud vocalizations are a way to establish territory in a habitat that allows few visual clues.

During the breeding season, the birds can be found across Canada, the northern half of the United States, and down through the intermountain west.

Soras construct a nest of dense vegetation along freshwater marshes. This location means the chance of flooding from heavy rains is always high. To help mitigate the risk, soras have large broods. The female lays eight to 11 eggs, one every day or so.

Because of brood size, older siblings can be far advanced by the time the last chick hatches. The chicks hatch after about two and a half weeks and can feed themselves from the first day after birth. They are ready for short trips away from the nest just a day after hatching.

In the fall, soras migrate south, using the Chesapeake as one of their first rest stops. Although they prefer fresh water during the summer, these rails visit coastal marshes every winter. In the East, soras are found from the Carolinas south to the Gulf states.

We, too, have temporarily migrated south, to the Merritt Island National Wildlife Refuge in Florida. The waters here are a mix of fresh and brackish, just like the Chesapeake. The sora's winter habitat extends west from here all the way to southern California and down to northern South America.

Soras eat seeds and aquatic invertebrates, pecking through the reeds and mire. Wild rice is a favorite food.

It can live for years before falling victim to a bobcat, fox or some accident. Perhaps a hunter will bag the bird.

My companions and I had a great view of the constantly moving sora before it slipped between some reeds, disappearing for good into the safety of the grasses.

It was late afternoon, and the sun was already setting on what was one of the shortest days of the year. Our glimpse of the secretive bird lasted just a few minutes.

With luck, this sora will live a few more years. Our own lives are measured in speeding decades. Time passes so quickly, I reflect, as another year recedes into the past.

In the weak glow of the winter's sun, I found myself wanting no more than this: to spend a few minutes in the vital heart of the natural world and to share this fleeting time with special people in my life.

We are caught in the ebb-tide of time. But for the moment, I was happy to have captured this sweet moment before the light finally faded.

Ross’s Goose - a rare visitor to Maryland

Diminutive Ross's goose connects a country
On the Wing / By Michael Burke - Bay Journal

A thousand Canada geese blanket the small pond and adjacent land. They are feeding, resting and making a continuous low racket with their irregular honking and wing flapping.

In other words, everything is perfectly normal for a winter’s day in Chesapeake country. Except, that is, for that small white goose sticking out like a brilliant pearl against a background of browns and blacks. My first thought is that it’s a snow goose; but it’s obviously too small. Besides its bill is, well, stubby.

I quickly consulted my pocket field guide, but I can’t find this bird.

Like many birders, I have a hefty “The Sibley Guide to Birds” in my car. I took careful note of his field marks, a task made easy by the goose’s slow grazing in the bright sunshine. After I’ve had my viewing fill, I head back to the car and the big field guide. And there it is on page 78: a Ross’s goose (Chen rossii). It’s my first encounter with a Ross’s—a rare visitor to Maryland.

The Ross’s goose looks remarkably like the snow goose. Like their cousins, they’re all white except for jet black wing tips. But the Ross’s wingspan is just 45 inches, compared with the snow goose’s 55 inches. What’s more, Ross’s goose weighs half as much, coming in at just less than 3 pounds.

And then there’s that bill. Snow geese and Canada geese have substantial bills. But this little Ross’s goose seems less formidable than his cousins, and I think that small bill is a big reason.

In the field, the overall size of a bird can be deceptive because of distance and lighting. There’s no mistaking the Ross’s stubby pink bill, however, for the more imposing variety worn by a snow goose.

Ross’s geese breed high in the Arctic tundra. Some nest on the western shore of Hudson Bay, but most nest even farther north in the Queen Maud Gulf Migratory Bird Sanctuary in Nunavut, Canada.

The much more common snow goose’s breeding range encompasses these areas and much more.

There is evidence that Ross’s and snow geese will sometimes interbreed. The Ross’s, like the snow, has a dark morph, but it is quite rare and Sibley speculates that the dark-feathered Ross’s may really be hybrids.

It takes three weeks for eggs to incubate in this northern nesting range. And it will take the young a month and a half before they are ready to fledge. The Ross’s goose feeds primarily on plant materials and aquatic invertebrates throughout their lifetimes.

When these geese head south for the winter they replicate their breeding geography. The Ross’s has just a few locations it frequents, while the more prevalent snow goose encompasses all those areas and quite a few more.

Ross’s usually winters in central California in the Sacramento Valley. A few go to New Mexico and others to the Texas Gulf Coast. Snow geese migrate to the same areas, although they form separate flocks on the winter range. Snow geese also winter on the East Coast, of course, including the Chesapeake. And this winter, so has a Ross’s.

A check of local Christmas bird count data reveals just how rare my sighting was. During many years, Maryland counts have only come up with a single individual. Some years show none.

As I take a second look at the Ross’s goose, my mind glides back to a pair of work trips I took to Sacramento last year.

The first was to discuss the differences and similarities between the Chesapeake Bay Program’s management efforts and those being utilized by its sister program known as CALFED. The second was a science conference in which the relatively young California effort was looking to the Chesapeake for comparative uses of environmental indicators.

But when I stood there on a Chesapeake tributary in the middle of winter, I realized that the most important connection is right in front of me. A Ross’s goose that typically winters in the Sacramento Valley is here this year. In either location it will need clean water, ample habitat and a steady supply of food.

It is the living resources that stretch across the continent that bind us. And it’s all carried off with elegant grace by this diminutive goose.

Snow Geese - The snow goose is about two-thirds the size of the Canada goose.

The Flight of the Snow Geese
Beginning New Year on the right webbed foot
On the Wing / By Michael Burke - Bay Journal

The temperature was a few degrees above freezing and the evening darkness was just starting to give way to the New Year as we entered the wildlife refuge. Sliding past scores of ducks and Canada geese as they began to grow restless on the first pond, we drove through a short stretch of loblolly pines and headed out onto the dikes.

To our right, thousands of snow geese blanketed the waters. The sun wouldn’t officially rise for another half hour, but this was already turning into be one of those brilliant winter mornings.

We quietly slipped out of the car, binoculars in hand.

Sporadic wing flapping and honking made the whole pond seem alive. And then—with a thunderous boom—the flock took to its wings, rising off the water like a skein of brilliant white yarn unraveling itself against the rosy dawn. The noise was near-deafening, as raucous geese honked madly and their wings beat against the morning sky. They rose with an awkward grace. Five thousand snow geese had just announced the arrival of 2006.

The snow goose (Chen caerulescens) is about two-thirds the size of its more familiar cousin, the Canada goose. The pure, white feathers on its head, body and wings are set off by wingtips of inky black. When the bird is resting on the water, this tucked-back wingtip looks like a short black tail on an otherwise all-white bird.

In spite of its name, not all snow geese are white. A dark morph, with bluish-gray upper parts and a brownish-gray underneath, has only a white upper neck and head, and is commonly referred to as a “blue goose.” Juveniles also lack the distinctive color of the most common form.

All snow geese have pink feet and a rather short, heavy pink bill with a black “grin” patch. The geese use those bills effectively in digging out and biting off tubers and the roots of marsh plants that constitute an important part of their diet.

As we had just witnessed, first light sends most snow geese off the ponds they use as nocturnal refuge. They fly across the countryside, where they will spend the day feeding on the remains of agricultural crops.

As dusk approaches, they once again congregate in huge mats like the ones we saw at Blackwater National Wildlife Refuge, on the Delmarva’s Eastern Shore.

Centuries ago, snow geese were common in the Chesapeake region. But the usual culprits, exploitative commercial hunting coupled with loss of habitat, decimated their numbers.

By the 1960s, snow geese were rare in these tidal areas. But limits on commercial hunting and the spread of the nation’s magnificent wildlife refuge system have led to a population explosion. Some experts now estimate that more than 500,000 snow geese annually winter on the coastal marshes of the Atlantic seaboard. Even more drop down from their Arctic breeding grounds every fall into the Pacific Northwest, California’s Central Valley, New Mexico, Mexico and the Gulf regions. The numbers have grown so large that biologists now worry that snow geese are putting too much pressure on tundra breeding areas.

Like many other species in their subfamily, Anserinae, snow geese frequently mate for life.

Often, the young stay with their parents through the first winter, exhibiting family bonds that are unusual in the avian world. Although the sexes are similar in appearance, only the female incubates the eggs on the small islands where they nest in the northernmost parts of North America. Both parents brood and protect the young.

When snow and ice threaten to cut off the birds’ food supply, Snow geese head south, and will migrate during day or night.

According to ornithologist David Allen Sibley, there are records of snow geese flying as high as 20,000 feet during mass migrations.

As with many bird species, the full range of biology and behavior of snow geese is of interest to me. But on that magnificent morning, I wasn’t looking at those birds with a clinical eye. We had told family and friends that we were going birding. But a desire to see promise and hope and new beginnings was the real reason for our trip.

As the thousands of snow geese lifted in unison, for a moment our hearts soared with them. The New Year dawned with this simple recognition: Moments of unspeakable beauty are still possible.

Chesapeake Bay Birds - Blackwater National Wildlife Refuge on the Delmarva Peninsula and other sites in the Chesapeake Bay Gateways Network

Geese a Pictorial Study
Smorgasbord makes Blackwater a winter hot spot for birds
Chesapeake Bay Gateways Network / By Cindy Ross - Bay Journal

"Development" in Maryland's Moneystump Swamp consists of a few duck blinds and yellow wildlife refuge signs. One is hard-pressed to find any people.

Tall, gangly pines sway and make music in the wind. Their tannic acid leeches into the waters, turning it "black."

We point our kayaks away from the bridge on MD Route 335, south of Cambridge, and into the headwind that is racing across the swamp.

And then we see them...eagles, high in the trees. Magnificent birds, dwarfing the snags they perch on. They spread their majestic wings, forcing us to throw back our heads in wonder and awe. We count more than a dozen in one spot! An astounding 130 or more bald eagles make Blackwater National Wildlife Refuge, a member of the Chesapeake Bay Gateways Network, their home.

Paddles are laid to rest across our thwarts and we don binoculars to watch the show. While some eagles soar, their mates keep vigil over their colossal nests, with heads and upper bodies poking above the mass of lumber. The nests are up to 11 feet deep and 8 feet across-one could hold several humans.

Blackwater is one of nine national wildlife refuges on the Delmarva Peninsula and by far the largest at 27,000 acres. Its tidal wetlands are brimming with loons, cormorants, grebes, ospreys, herons, egrets, ibis, geese, ducks-the refuge's bird list includes 250 species with 20 species of ducks alone.

So many species come to the Blackwater to overwinter, it is an ideal time to visit, and an especially good time to view waterfowl, long a signature species for the Chesapeake region.

These birds have flown thousands of miles from the Arctic, where they converged and had their young. Now they have returned. Using the sun and the stars, they tracked the Earth's magnetic fields like a compass. Youngsters flew with the elders, memorizing the route.

The Chesapeake Bay area is an important staging ground, hosting one-third of all migratory waterfowl wintering on the Atlantic coast. Approximately 1 million migrants make their home around the Bay for at least part of the year.

In the 1800s, the population of waterfowl was even more spectacular.

This abundance drew hunters to the Eastern Shore. What began as a means to feed their families, though, developed into a wasteful, devastating sport. Meanwhile, wetlands had been developed, transformed into agricultural fields. Birds were also shot for their feathers to adorn ladies' hats. But by the early 1900s, the seemingly endless numbers of birds were dwindling at an alarming rate.

Insightful conservation leaders realized the approaching demise. Their response led to regulations being put in place and the U.S. Fish & Wildlife Service's establishment of a system of 540 wildlife refuges, including several around the Bay. One of the feathers in the system's hat and the Chesapeake's prime refuge is Blackwater in Dorchester County, MD, which was established in 1933 for migratory birds, primarily ducks and geese.

This colossal wildlife refuge, along with the state of Maryland's adjoining Fishing Bay Wildlife Management Area, is affectionately called "The Everglades of Maryland." It appears as a vast green wild area on a state highway map-a remote wilderness of meandering creeks, marsh grass habitats, secluded ponds and islands of loblolly pines. This is remarkable in the congested mid-Atlantic seaboard.

The best way to see this predominately watery landscape is by boat. The nonprofit Friends of the Blackwater organization has created three signed water trails, making it much easier to navigate this often-challenging ecosystem. We selected the Green Trail on the upper reaches of the Blackwater River, which is considered the most scenic and is also where bald eagles like to hang out.

We paddle into Buttons Creek and watch Cooper's hawks, winter hawks and red-tailed hawks surf the currents. Kingfishers, terns, cormorants and great blue herons keep our binoculars poised in position. Massive swarms of migrating red-winged blackbirds volley for our attention.

We also watch the rare and endangered Delmarva fox squirrel climb up the trunks of a loblolly pine. One doesn't need to be a birding expert to appreciate the richness of waterfowl and wildlife here in the refuge.

After a morning paddle, we hop in our car and take the refuge's 4-mile Wildlife Drive. This dawn-to-dusk paved road snakes around pools and the Blackwater River, featuring 11 points of interest.

We look for large numbers of Canada geese-the refuge is one of the chief wintering areas for those using the Atlantic Flyway. Geese number approximately 35,000 and ducks exceed 15,000 at the peak of fall migration, usually in November. We stretch our legs on the 4.5 miles of trails and boardwalks that bring visitors up close to the wintering waterfowl. For a sunset walk and to continue our search for birds, we take the scenic drive to Hooper Island.

One of the reasons millions of waterfowl make their home on the Chesapeake is the available smorgasbord. Both fresh and saltwater aquatic grasses grow abundantly in sheltered, shallow waters. Meanwhile, a feast of small marine animals multiply in the protective grass beds.

While scouting around the Delmarva Peninsula and the Chesapeake Bay in the winter, one might expect to see thousands of birds grouped together, but the land is so big and the refuges so vast, that the waterfowl tend to spread out.

December and January are blustery months for birding, but the occasional midwinter thaw is a great time to get out with your binoculars and keep the wintering waterfowl company. Whole days can be spent exploring numerous waterfowl hot spots around the Bay.

By late February and early March, the migrants are congregating and heading out.

As warmer breezes return to the mid-Atlantic seaboard, ice breaks up on the ponds and lakes and the heads of tasty green winter wheat poke up through the fertile farmlands of Pennsylvania.

If one is a snow goose, one is thinking of leaving the Chesapeake and heading north. If one is a bird gawker, one is thinking of heading to Middle Creek Wildlife Management Area, which straddles Lebanon and Lancaster counties and is managed by the Pennsylvania Game Commission.

The sky is beginning to glow pink as I bank a turn into the entrance of Middle Creek. I hustle down the Willow Point Trail with a sense of urgency, zipping my parka as I go. I don't want to miss the show that is about to begin.

I cock an ear toward the body of water to my left, on the far side of the woods. I can't see the 100,000 snow geese that float on the sheltered lagoon, but I can make out their gibbering voices.

It's late February, and these migrating, snow-white birds have made this wildlife refuge their home for a few weeks. They have come from the Chesapeake Bay area, where they wintered over, and Middle Creek is their first staging area. After they fatten up on the local farmers' crops, they'll continue on to the St. Lawrence River in Canada, and later, the Arctic, their mating and breeding grounds.

The first shreds of light enable me to make out their bobbing bodies on the lake-there are so many that I see a blanket of white instead of dark water. They have very slowly, almost imperceptibly, begun to spread out onto the 400-acre lake, to position themselves for takeoff.

Suddenly, the cold morning air is filled with goose voices, excitedly growing louder and louder until they are almost yelling. They rise up from the lake in a great sweeping wave, flapping their wings to take off. One hundred thousand white birds, their brilliant bodies reflecting the sunrise, swirl around my head in a great arch, moving as a single organism.

They engulf me. I throw my head back and stare mesmerized. In a matter of seconds, they're gone in the direction of today's meal, not to return until the last light graces the evening sky. In only a matter of seconds, the show is over, and I am left speechless.

By mid-late March, the snow geese begin to leave Middle Creek by the tens of thousands. Some years, 50,000 to 60,000 will head out on a single morning. The entire lake can clear out in a single day. The Great Lakes staging area calls them and their magnificent journey from the Chesapeake to the Arctic continues.

Where to flock to see waterfowl around the Bay watershed
Situated along the Atlantic flyway, the Chesapeake 's vast wetlands and expanses of shallow water are magnets for migrating waterfowl, which often overwinter here or stop en route from their northern summer breeding grounds. Once there were millions. Today, a decline in the quantity and types of underwater grasses; overhunting; more people; and shrinking habitat have cut their overall numbers to about 1 million. Dozens of sites in the Chesapeake Bay Gateways Network offer opportunities to view waterfowl or learn about waterfowl heritage, such as decoy carving. The sites here highlight some of what's available.
  • Havre de Grace Decoy Museum, Havre de Grace, MD: Located on the banks of the Susquehanna Flats, the museum features decoys and decorative carvings, as well as boats, guns, documents and photographs.
  • Marshy Point Park, Baltimore, MD: This park along the Dundee and Saltpeter creeks is the largest natural wetlands and forest open to the public in the Baltimore area. Dundee Creek is home to 11 thriving species of submerged aquatic vegetation that attract flocks of tundra swans and 20 species of waterfowl.
  • Patuxent Research Refuge-National Wildlife Visitor Center, Laurel, MD: The refuge encompasses 12,750 acres of land surrounding the Patuxent and Little Patuxent rivers between the District of Columbia and Baltimore. It supports a diversity of wildlife in forest, meadow, and wetland habitats. More than 200 species of birds are found on the refuge.
  • Eastern Neck National Wildlife Refuge, Rock Hall, MD: This island refuge at the confluence of the Chester River and the Chesapeake Bay includes a tidal marsh, upland forest and croplands managed for wildlife. It is an important migration stop and wintering area for more than two dozen waterfowl species and is a major staging and wintering area of the tundra swan.
  • Chesapeake Bay Environmental Center, Grasonville, MD: This 500-acre preserve is located 15 minutes from the Chesapeake Bay Bridge. Wintering waterfowl include the canvasback, American black duck, shoveler, ruddy duck, redhead, Canada goose and tundra swan.
  • Wye Island Natural Resource Management Area, Queenstown, MD: Located in the tidal recesses of the Chesapeake Bay between the Wye and Wye East rivers, this site includes 2,800 acres of habitat for wintering waterfowl populations and other native wildlife.
  • J. Millard Tawes Historical Museum & Ward Brothers Workshop, Crisfield, MD: Among the museum's many exhibits is the evolution of decoy carving and painting, which is highlighted during tours of the Ward Brothers Workshop.
  • Rappahannock River Valley National Wildlife Refuge, Warsaw, VA: This site is part of the Eastern Virginia Rivers National Wildlife Refuge Complex. The refuge protects and manages tidal and inland wetlands and adjacent uplands. More than 200 species of birds have been observed here, and bald eagles are present year-round.
  • Eastern Shore of Virginia National Wildlife Refuge: Located at the southern tip of the Delmarva Peninsula, it is a gathering place for migrating birds, which wait for favorable conditions to cross the Bay in the fall. In the spring, shallow waters and moist grassy areas provide food for marsh and shorebirds.

Cindy Ross lives in Pennsylvania and unlike some children today, has a hard time coming indoors. She has written six books about it; her latest, from McGraw-Hill, is "Scraping Heaven: A Family's Journey Along the Continental Divide." She fears she has inflicted her children with the same addiction to fun in the outdoors.

Peregrine Falcons - Birds of Prey

Peregrine Falcon: Dive, Dive, Dive! (Blink of An Eye: Superfast Animals)
Peregrine falcons soaring back from the brink of extinction
Bay Naturalist / By Kathy Reshetiloff  - Bay Journal

In 1999, when the American peregrine falcon was removed from the list of endangered species, the bird’s recovery from near extinction in North America was hailed as a tremendous conservation success story. Today, the peregrine’s recovery continues at an impressive pace.

The U.S. Fish and Wildlife Service released the results from the first nationwide monitoring effort measuring the peregrine falcon’s recovery, which put the number of nesting pairs in North America at about 3,000—nearly 10 times the number estimated in 1970 when the bird was first protected as an endangered species and considerably more than the roughly 1,800 breeding pairs estimated in 1999, when the peregrine was declared recovered and de-listed.

In 2003, the first year of post-delisting monitoring, more than 300 observers—many representatives from the same partners who supported the recovery effort—monitored 438 peregrine falcon territories across six regions. Surveyed areas included the Northeast/Great Lakes, Southeast, Southwest, Rocky Mountains, Pacific and Alaska.

A second round of monitoring was done this year, and preliminary results indicate that the peregrine population continues to grow. Final results and analyses from 2006 will be published in a report in the summer of 2007. Monitoring will continue in 2009, 2012 and 2015. The monitoring of contaminant levels in eggs and feathers will be reported in the future as well.

A medium-size bird of prey, an adult peregrine falcon is slate gray on the head and back, barred and spotted on the underside, and has distinctive black “sideburns.” Like other falcons, the peregrine has long, pointed wings and a slender tail. Immature peregrines have brown backs with heavy dark streaks below.

Historically, the peregrine falcon ranged throughout North America and much of the rest of the world. In the eastern United States, they nested from the Great Lakes and eastern Maine south to Georgia and Alabama.

The peregrine falcon feeds primarily on other birds. Shorebirds, blackbirds, robins, jays and flickers are commonly taken. Prey ranges in size from swallows to large ducks.

After World War II, the use of new insecticides known as chlorinated hydrocarbons increased. Simultaneously, the populations of peregrines, bald eagles, and other birds of prey began to decrease. Small birds and mammals ate invertebrates contaminated with pesticides. Eagles and falcons feeding on contaminated birds and rodents were, in turn, poisoned by the progressive buildup of pesticides in their body tissue.

DDT, a widely used pesticide, was especially harmful because it caused eggshell thinning and, therefore, reduced reproductive success. Although adult birds survived, they could not produce offspring.

By 1964, nesting peregrines were extinct in the eastern United States. Peregrines still nesting in the western part of the country were listed as endangered in 1970, two years before DDT was finally banned from use.

During the recovery effort, more than 6,000 peregrine falcons were released into the wild by government and private raptor specialists.

Some of the reintroductions took place in urban areas after researchers discovered that the falcons can successfully adapt to nesting on skyscrapers and other urban structures, where the abundant pigeons and starlings are the mainstay of their diets. In the Northeast and Midwest, two-thirds of peregrine falcons nest on man-made structures.

In addition to the DDT ban, the recovery of the peregrine falcon has been credited to protections afforded by the Endangered Species Act. Combined efforts of the federal and state wildlife agencies, universities, private organizations and falcon enthusiasts greatly accelerated captive breeding programs, reintroduction efforts and the protection of nest sites during the breeding season.

Similar efforts took place in Canada.

Facts About Owls - A single barn owl can eat more than a thousand mice in a year!

Owls of the World
Nightlife has earned owls undeserved dark reputation
Bay Naturalist / By Kathy Reshetiloff - Bay Journal

I woke abruptly, not knowing what exactly had punctuated my sleep. It was still dark and I listened intently. This time I heard it…hoo-hoo-hoo-haaw. A barred owl called from the woods. Soon another owl, slightly farther away, responded. I drifted to sleep as the pair continued to call, one enticing the other a little closer.

Because of their nocturnal nature, owls have been viewed as bad omens or messengers of misfortune and even death. In spite of their sometimes sinister appearance and ghostly calls, owls are particularly valuable as rodent predators. They are actually quite beneficial, economically: A single barn owl can eat more than a thousand mice in a year!

Formidable hunters, owls arrive upon their prey without a sound. A modification to their flight feathers makes this possible. The wings have downy fringes along the stiff flight feathers that muffle sound as the owl approaches its prey.

Owls probably have the most acute hearing of any bird. They can hear sounds 10 times fainter than a person can detect. Several features of an owl’s ear make this possible.

Owls have an extra-large ear opening surrounded by deep, soft feathers that funnel sound. Furthermore, the feathers over the ear, the auriculars, are modified to be loose and airy.

Owls also have a moveable flap of skin controlled by muscles around the ear opening. This flap protects the ear and concentrates sound waves coming from behind. Many owls also have asymmetrical ear openings. The opening in one ear will be higher than in the other ear. A sound coming from above will sound slightly louder in the ear with the higher ear opening. This allows the owl to pinpoint its prey accurately.

Finally, the owl’s entire face acts as an outer ear. The face is shaped like two satellite dishes that funnels sound to the ears. The compact facial feathers aid in the funneling process. Some owls have ear tufts, feathers sticking up on the top of both sides of the head. Ear tufts do nothing to improve hearing. Ear tufts make the owl appear larger, which helps to ward off predators.

In general, all birds have relatively large eyes compared to the size of their head. A human eye weighs less than 1 percent of the weight of the head. But owls have the largest eyes. In fact, if people had eyes proportional to those of the great horned owl, our eyes would be the size of grapefruits and weigh 5 pounds!

Owl eyes are so large that there is little room in their skulls for eye muscles. Thus, an owl turns its head, sometimes as much as 270 degrees, rather than move its eyes to follow an object.

It’s been said that the difference between the hunter and the hunted is evident in the eyes. The hunted have eyes on the sides of their heads to obtain a wide field of view. Hunters have eyes on the front of their heads to increase depth perception. Owls have the most frontally positioned eyes of any animal.

Contrary to popular belief, owls have excellent vision both in daylight and at night. Their pupils are huge at night, letting in great quantities of light and in daytime shrink down to the size of a pinpoint. Their eyes are 10 times as light-sensitive as human eyes. This is due the concentration of light-sensitive rods in the retina but is at the expense of color defining cones. So, although they see well in dim light, owls see little color.

Because they swallow their prey whole or nearly so, owls regurgitate pellets containing undigested parts of their prey. They can digest all but the bones, feathers or fur. They eject this matter in the form of a hard fur or feathered pellet.

By dissecting pellets, scientists are able to determine just what animals an owl is eating. Even if they eat insects, the pellet will contain the hard exoskeleton.

Owls do not build their own nests. Instead, they use old hawk nests, squirrel nests, natural cavities, buildings or constructed boxes.

There are several species of owls that inhabit the Chesapeake Bay region. Probably the most familiar of these is the great horned owl. This large brown owl is noted by its large yellow eyes, white throat patch and large ear tufts. It can be recognized by its call—a series of low hoots: hoo-hoo hooo hoo-hoo. Another “eared” owl is the long-eared owl, which is similar in appearance to the great horned except that its ears tufts are closer together and it is smaller and slimmer.

The eastern screech owl is a small—8 inches long—eared owl with coloring varying from rust to gray. Its call is a long quivering whistle.

Of the earless owls, the barn owl is easily recognized by its light colors and heart shaped face. As the name implies, the barn owl nests in barns, abandoned buildings and tree cavities. Its song is a long, raspy screech.

The barred owl is often referred to as the “hoot owl.” Its call is made of nine hoots that sound like the phrase Who-cooks- for-you, who-cooks-for-you-all?

The northern saw-whet owl is the smallest of the eastern owls—7 inches long—and is often found roosting in dense evergreens or in thickets. Its call is a series of toots or whistles.

Owls have been the subject of much misunderstanding, superstition and fancy. Over the centuries, people’s views of these wonderful birds have changed. They have been used to represent doom and evil as well as knowledge and wisdom. Their importance to our environment has also changed.

As more and more land is developed, many of our natural predators are lost. Left unchecked, rodents and other small mammals can become pests. Owls continue to play a significant role in our ecosystem by controlling these populations.

Putting ecological benefits aside, though, I just love falling asleep to the eerie hooting of an owl on a cold winter night.
