It’s a bird! It’s a plane? No, wait, you can hear that it’s a bird. Tracking bird migration can be tricky, especially in a dark sky. But when individual species of birds talk with each other through flight calls, researchers can listen in to determine exactly what species are flying overhead. And now, researchers are developing a computer system — dubbed BirdVox — that automatically picks out and identifies the bird sounds. In this podcast, I chat with creators of BirdVox to learn how they cut through the noise and get to the birds.
