TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of February 7, 2022. This revised episode from December 2019 is part of a series this year of winter-related episodes.
SOUND – ~ 5 sec.
This week, we feature a feathered Virginia
winter-resident mystery sound. Have a listen to the sound for about
10 more seconds, and see if you know a relatively small, dark-colored goose
species that migrates from Arctic shores to the mid-Atlantic coast for the
winter. And here’s a hint: the name rhymes with migrant.
SOUNDS - ~10 sec.
If you guessed the Brant, you’re right! From its summer breeding grounds in northern Canada and Greenland, the Brant travels to wintering areas along the Atlantic from Massachusetts to North Carolina, including coastal Virginia and the Chesapeake Bay region. That’s the pathway for eastern sub-populations of the species; western sub-populations migrate from Arctic parts of Canada and Alaska to the Pacific coastline.
One of eight species of geese native to North America, Brant live in a variety of saltwater or estuarine habitats, feeding mostly on a number of kinds of aquatic plants. In their winter habitats along the Atlantic Coast and around the Chesapeake, they prefer areas where they can feed on Eelgrass [Zostera marina]. Wintering Brant will eat various other aquatic plants, too, especially in response to reduced populations of Eelgrass. According to the Cornell Lab of Ornithology, however, Brant are more dependent on a single food type than other geese species, and this dependence can make Brant more vulnerable than other geese to starvation in some years. Regarding Brant winter feeding, the Cornell Lab notes that severe conditions in eastern North America during the winter of 1976 and 1977 kept Brant from traditional winter habitats for several months. As a result, Brant that year moved inland to feed in agricultural fields, suburban lawns, and golf courses, and over 40 years later, eastern Brant still forage inland from New York to Virginia.
Thanks to Lang Elliott for permission to use this week’s sounds, from the Stokes Field Guide to Bird Songs. We close with about 40 seconds of music for Brant and other kinds of geese. Here’s “Geese Piece,” by Torrin Hallett, and graduate student at the Yale School of Music.
MUSIC - ~43 sec – instrumental.
Virginia Water Radio is produced by the Virginia Water Resources Research Center, part of Virginia Tech’s College of Natural Resources and Environment.

EXTRA INFORMATION ABOUT BRANT
The scientific name of the Brant is Branta bernicla.
Here are some points about Brant, excerpted from the Virginia Department of Wildlife Resources (formerly Department of Game and Inland Fisheries), “Fish and Wildlife Information Service/Brant/Life History/Brant,” online at https://services.dwr.virginia.gov/fwis/booklet.html?&bova=040046&Menu=_.Taxonomy&version=19030, as of 2-7-22.
“The adult neck and head are black, except for a broken white crescent on each side of the neck. The bill is black and the eye is brown. The chest and foreback are black, sharply defined against the breast and sides. The back and scapulars are brown with the feathers vaguely tipped with lighter brown. The rump is dusky brown to dusky, with the sides of the rump white. The forebreast and sides are pale ashy-gray, and the feathers of the sides are slightly browner, and broadly tipped with white. The breast, belly and flanks are pale grayish to light grayish-brown. The feet are black, and the tail is black….”
Nesting Habitat and Behavior
“This species breeds in Arctic North America, Arctic islands, northern Canada, [and] Greenland off- shore islands, river deltas, marshy uplands, and tundra lakes. This species is seldom far from the coast. They use marshy ground, sandy beaches, talus slopes, coastal sedge tundra, lowland coastal tundra just above the high tide line, low islands of tundra lakes and dry inland slopes covered with vegetation, low grass-covered flats dissected by tidal streams, [and] grassy islands and grassy slopes of low mountains near the coast. The nest site is always in the open, on offshore or lake islands, or on low lying land. …The nest cover is low, thick, grass or sedge mat vegetation. They nest in colonies. …The nest is initially a depression formed in soggy earth. Sedges are molded around the scrape and down is later added. …The young are led to tidal flats or pools where they consume quantities of insects as well as grass….”
Winter Habitat (of Eastern Sub-populations)
“Non-breeding habitat is on the Atlantic Coast from Massachusetts to North Carolina. They are coastal but also occur in lower Chesapeake Bay, the mouth of Chesapeake Bay, Chincoteague Bay, Gargathy Bay, and Accomack County. Most of the time the 8000 that winter in Virginia are concentrated in Back Bay, [other] bays, tidal flats with abundant pondweed growth, mudflats, …lagoons, estuaries, saltmarshes, islands, …marine habitat, and shallow expanses of saltwater. They are most abundant on Chesapeake Bay on the barrier beach side of the bays. They may be in shallow areas of brackish water. They are gregarious, and often form large rafts on open water while feeding and resting. They rest on sandbars, and roost on banks or on water near the feeding grounds.”
“This species forages in water, mud, and fields. It immerses the head and neck and grazes or up-ends. This species prefers to feed in bays, shallow plant filled waters on the leeward side of barrier islands, spits, and sandbars and grassy fields. This species feeds at low tide and does not dive. …The juveniles eat insects, grass, larvae, small crustaceans, sedge, marine invertebrates, mosquito larvae, and pondweed. Eelgrass is the primary food, and they have been recently feeding extensively on sea lettuce due to the destruction of eelgrass beds. They may also graze on saltmarsh pastures. Other foods include moss, lichens, algae, sea lettuce, widgeon grass, …sedge, [and other materials]. …Animal foods are taken accidentally and include fish eggs, worms, snails, amphipods, insects, crustaceans, and clams. When saltmarshes and bays freeze over, they will graze on grass planted in yards.”
