TRANSCRIPT


From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of March 4, 2013.

This week, we feature music merged with a mystery sound, both meant to ask: What Virginia animals range from rocky ridges to still-water swamps, and generate an equally wide range of human reactions?  Have a listen for about 40 seconds.

SOUND.


If you guessed snakes, you’re right!  That was the sound of a Timber Rattlesnake, in between parts of “Baldcypress Swamp,” performed by Timothy Seaman on the 2004 CD “Virginia Wildlife.”  Virginia has over 30 species of snakes.  Some prefer dry, upland areas, but many species inhabit aquatic areas ranging from marshes and swamps to streams and rivers.  Virginia has three poisonous* species: Timber Rattlesnake, including a Coastal Plain population called the Canebrake Rattlesnake; Northern Copperhead; and Eastern Cottonmouth.  The latter is often confused with the widespread but non-poisonous Northern Watersnake, with both having the common name Water Moccasin.  Such cases of mistaken snake identities, along with misunderstandings of snake behavior, help cause widespread human fear and dislike of snakes.  But even if snakes give you the creeps, learning a little bit about these reptiles can increase your appreciation for their key role as predator and prey within various land and water environments.  Thanks to Timothy Seaman for this week’s music and to the Virginia Department of Game and Inland Fisheries for the Timber Rattlesnake sound.

[*Editor's note: Scientists use the more accurate term "venomous" snakes.  This makes the distinction that such snakes actively inject toxins, rather than simply being harmful if eaten by something.]
