From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of November 28, 2011.
This week we feature another mystery sound. Have a listen for about 20 seconds and see if you can guess what kind of winter Virginia visitor is making these calls. And here’s a hint: the name might suggest looking graceful in a very cold place.
If you guessed Tundra Swans, you’re right! Tundra Swans, formerly called Whistling Swans, breed in the Arctic but winter along the Atlantic, Pacific, and Gulf coasts. In Virginia, the birds are found between November and March around the Chesapeake Bay, on the Eastern Shore, and in Back Bay in Virginia Beach. Tundra Swans are one of three swan species potentially found in Virginia. Non-native Mute Swans live year-round on park land and golf courses but also in natural habitats, where their aggressive behavior can displace Tundra Swans and other native birds. And Trumpeter Swans historically migrated through Virginia, but by the 1900s commercial harvests, habitat loss, and pollution had removed this species from most eastern U.S. areas. Decades of conservation efforts, however, are helping restore Trumpeter Swan populations. Thanks to Lang Elliott of NatureSound Studio and to the U.S. Fish and Wildlife Service for permission to use this week’s recordings.
