From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of November 14, 2011.
This week we feature another mystery sound. Have a listen for about 20 seconds, and see if you can identify what’s making the various high-pitched calls, which may sound like a yodel, hoot, or wail.
If you guessed a loon, you’re right! The distinctive calls of loons are associated with lakes and other water bodies in Canada and the northern United States, where five species of loons breed. But Virginia’s coastal areas provide winter homes for two species, the Common Loon and Red-Throated Loon. Unfortunately for Virginians, however, these birds do not make their calls in winter. Loons are known for their swimming and diving abilities, and they typically go on land only during breeding. The Common Loon, as its name implies, is well-known as a symbol of wildlife and wilderness, and the species has been extensively studied as an indicator of water quality, including particularly the effects of mercury and acid rain. Thanks to the U.S. Fish and Wildlife Service and to Lang Elliott of NatureSound Studio for this week’s sounds.
