“Birds have a two-sided voice box. It’s called a syrinx and in songbirds each side is controlled independently, allowing some—like the Wood Thrush—to sing rising and falling notes simultaneously. This vocal feat far outpaces even the most talented human singers because our larynx can only produce one sound at time.”
How awesome is that? And did you know songbirds need to learn and practice their song? On this beautiful site, Bird Academy, among many other things, there is an interactive guide to the world of song. As you go through this short interactive feature, you can learn pretty much, play a sound visualization game, watch animation of the birds’ voice box, and musicians try to imitate birdsong by tweeking their own voice. In the end, you’ll get free bird song samples to download!
