Amazing Natural Bird Sounds
A Red-eyed Vireo sings more than 20,000 songs a day. A Pileated Woodpecker drums on a tree at 15 beats per second. A Wilson's Snipe dives through the air, the feathers on its wings vibrating to produce a winnowing sound, hu-hu-hu...
Why? Birds put a lot of effort into singing, drumming, winnowing, and otherwise displaying. They are trying to impress mates and proclaim territories.
