This is more or less like the grown-up, nerded-out scientist version of those spinny roulette toys you had as a kid that taught you that The Cow Goes Moo. Except the Cornell Lab of Ornithology's Macaulay Library tells you that the katydid goes, uhhh, "dial-up modem noise"?
More or less. The Macaulay Library just went live with 150,000 sounds (7500 hours worth) from 9000 different animals — totally centred around birds, as you'd expect from an ornithology department. The library also contains almost 50,000 videos — and you can contribute your own field recordings too. It's a perfectly geeky way to waste an hour or 7000 today. [Cornell via PopSci]
