TRANSCRIPT


From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of February 25, 2013.

This week, we feature a series of mystery sounds.  Have a listen for about 35 seconds, and see if you can guess what kind of animals these six creatures are, and what they have in common.  And here’s a hint: if you think cold, you’re warm!

SOUNDS.


If you guessed all birds, you’re right!  The sounds, in order, were from the Horned Grebe, Dunlin, American Coot, Hooded Merganser, Tundra Swan, and Snow Goose.  And one characteristic they share is that they are winter residents around Chesapeake Bay area waters.  According to Life in the Chesapeake Bay, by Alice and Robert Lippson, some 22 bird species are commonly found in winter around the Bay but are uncommon or not present at all during summer.  And a similar number of Bay-area bird species are just the opposite—rare in winter but common in warmer months.  So as spring arrives, the first of two yearly feathered comings-and-goings will start to fill the skies over Virginia’s coastal waters.  Thanks to the Lang Elliott and NatureSound Studio for permission to use the grebe, dunlin, coot, and merganser sounds, and to the U.S. Fish and Wildlife Service for the swan and Snow Goose sounds.
