I happen to like birds. As a kid I didn't really care about them but as I grew older I started to admire them. The freedom their wings provide, watching them soar through the sky (and I swear it seems like sometimes birds just fly for the fun of flying around...) I love crows, the fact that they pair-off for life, and their intelligence and seeming boldness.
Anyway, if you're a bird enthusiast too, here's a source of bird calls for you via Science News:
The Macaulay Library at Cornell University has the largest collection of animal sounds in the world. More than 67 percent of the world's birds are represented in the center's 160,000 recordings, along with sounds made by insects, fish, frogs, and mammals. The Library also archives and preserves a sampling of the behaviors of different animal species using digital video and audio. Download the songs of various backyard birds, from chickadees to goldfinches, at the following Web page.
