From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of June 25, 2012.
This week we feature another mystery sound. Have a listen for about 15 seconds and see if you can guess what’s making the high-pitched, chirping sounds. And here’s a hint: You won’t find an image of this bird on the back of a U.S. quarter, but you can find it commonly along Virginia’s tidal and coastal waters in spring and summer.
If you guessed an Osprey, you’re right! Sometimes mistaken for Bald Eagles, adult Osprey differ from our national bird in having white under their wings and dark marks on their head and tail. Like Bald Eagles, however, an Osprey’s sharp talons, hooked beak, and keen eyesight make it a raptor, a word whose Latin root means “to seize.” While many raptors capture a variety of animals, aquatic-based Osprey feed almost completely on fish—giving rise to its nickname, Fish Hawk. A ban on the use of the pesticide DDT in the United States greatly helped the recovery of severely diminished populations of Osprey, eagles, and other birds, whose eggshells were thinned by the chemical. Osprey nest along shorelines, rivers, and marshes in the Chesapeake Bay region from spring to late summer. Thanks to Lang Elliott of NatureSound Studio for permission to use this week’s sound.
