TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of December 7, 2020. This episode is a revised repeat of an episode from November 2011.
SOUND – ~6 sec
This week, we feature mystery sounds from a long-necked and white-feathered winter visitor to Virginia. Have a listen for about 20 seconds and see if you can guess what’s making these calls. And here’s a hint: the name might suggest gracefulness in a very cold place.
SOUND – ~19 sec
If you guessed Tundra Swans, you’re right! You heard, first, individual Tundra Swan calls in a recording by Lang Elliott from the Stokes Field Guide to Bird Songs; and second, a Tundra Swan flock, in a U.S. Fish and Wildlife Service recording. Formerly called Whistling Swans, this species gets its current name from the birds’ breeding range in the treeless, Arctic habitat known as tundra. In the non-breeding winter season, Tundra Swans are found along the Atlantic and Pacific coasts, with the Chesapeake Bay being a key area. Between fall and early spring in the Bay region, large flocks inhabit lakes, rivers, bays, estuaries, and flooded fields. They feed in shallow water on aquatic plants and animals, particularly clams. They also feed on grains in agricultural fields. In turn, their eggs and young are preyed upon by various mammals and birds. And swans are sometimes victims of a behavior called kleptoparasitism, when swooping gulls steal a clam right out of a swan’s bill.
The Tundra Swan is the most widespread of three swan species found in North America; the other two are the native Trumpeter Swan and the non-native Mute Swan. The Trumpeter Swan, whose large historical wintering range included Virginia, was pushed to near extinction in the 1900s by habitat loss, pollution, and hunting for their feathers; the population is now expanding following conservation efforts. The Mute Swan, originally from Europe and Asia, has become widely established in the United States, living year-round in parks and other human spaces but also in natural habitats, where its aggressive behavior can displace native species.
Thanks to Lang Elliott and to the U.S. Fish and Wildlife Service for the Tundra Swan sounds. We close with about 45 seconds of music composed for this episode by Torrin Hallett, a graduate student at Lamont School of Music in Denver. Here’s “Tundra Swan Song.”
MUSIC – ~ 44 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. For more Virginia water sounds, music, or information, visit us online at virginiawaterradio.org, or call the Water Center at (540) 231-5624. Thanks to Stewart Scales for his banjo version of Cripple Creek to open and close this show. In Blacksburg, I’m Alan Raflo, thanking you for listening, and wishing you health, wisdom, and good water.
AUDIO NOTES AND ACKNOWLEDGEMENTS
This Virginia Water Radio episode revises and replaces Episode 90, 11-28-11.

The sound of a Tundra Swan flock (second set of featured “mystery sounds”) was taken from the U.S. Fish and Wildlife Service’s Sound Clips Web site at http://www.fws.gov/video/sound.htm.

EXTRA INFORMATION ABOUT TUNDRA SWANS
The scientific name of the Tundra Swan is Cygnus columbianus.
The following information is excerpted from the Virginia Department of Wildlife Resources (formerly Department of Game and Inland Fisheries), “Fish and Wildlife Information Service/Tundra Swan,” online at https://vafwis.dgif.virginia.gov/fwis/booklet.html?&bova=040044&Menu=_.Taxonomy&version=18600.
“The adult is completely white. The legs and feet are black and the bill is typically black except for a small yellow area in front of the eye although some lack this yellow mark. The females are slightly smaller than the males. …”
“The breeding season is from May-June. Hatching occurs from late June to July. …This species is monogamous, and they pair for life. Pair formation begins in wintering flocks and is gradual and inconspicuous. The male defends the female from intruders and returns to her to perform a triumph ceremony. …”
“They are strongly territorial and will sometimes threaten with the head submerged. …Migration is along the major migration corridor from Alaska to Chesapeake Bay. They migrate as family units and several families and non-breeding birds combine in a single flock. …The Chesapeake Bay migration is as follows: Fall = October 15-December 5, peak = October 25-November 30; Spring = February 25-April 30, peak = March 10-April 1.”
“They feed in shallow water and usually just immerses the head and neck. They may tip-up in deeper water *425*. Foods are taken from the bottoms of marshes and small lakes. This species usually does not dive for food. This species does great damage on feeding grounds by creating holes in the mud and trampling vegetation. They are grazers and grubbers on land. They pull up and eat entire plants. They feed mainly in extensive shallow, fresh and brackish waters. …In the Chesapeake Bay, brackish estuarine bay foods include widgeon grass and pondweed. Fresh estuarine bay foods include wild celery and pondweed. Important foods are leaves, stems, and roots of submerged aquatics. Foods include tubers and seeds of pondweed, leaves, stems, and tubers of aquatic and marsh plants, corn, potatoes, soybeans, winter wheat, frogs, minnows, shellfish, wild celery, and fox-tail grass. They feed in Chesapeake Bay area corn stubble fields. They take naiads, mollusks, bivalves, roots and stems of emergent marsh plants, herbaceous fruit, adult insects, snails, worms, fish fry and adults, tadpoles,, tubers of arrowheads, lady's thumb, horsetail, and burr reed.”
“Nesting and nest sites are from the Arctic Coast south to the Alaska Peninsula and barren ground of Canada. They are also north of the Arctic Circle or the near the Arctic and south along the west side of Hudson Bay. 60% nest in Alaska on tundra, the main shore of a lake or pond within 20 yards of water, small islands or points in lakes heath tundra, hummocks in marshes or tidal meadows, or rarely on level stretches in marsh or meadow areas. …”
“Chesapeake Bay is the most important wintering ground. A few winter on the Great Lakes and on the seaboards of the east and west coasts of the United States. 48% winter in the Atlantic flyway. Chesapeake Bay has 40000/year. Back Bay, Virginia to Pamlico Sound, North Carolina has 14000. They are found on lakes, large rivers, bays, estuaries, flooded fields, salt lakes, and temporarily flooded areas. In the Chesapeake Bay, 76% are found in brackish estuarine bays, 9% in salt estuarine bays, 8% in fresh estuarine bays, and 6% in slightly brackish estuarine bays. They winter as family units. They form large wintering flocks and are highly social.”
