WRS -- Macaulay Library Sound and Video Catalog

From http://www.animalbehaviorarchive.org/:


"The Macaulay Library is the world's largest archive of animal sounds.We have more than 160,000 recordings of 67 percent of the world's birds, and rapidly increasing holdings of insects, fish, frogs, and mammals."

These recordings, as well as selected video recordings of animal behavior, are available to be listened to or watched free on the site. Really great place to go if you've ever wondered just what a particular animal sounds like in the wild.
