Having Your Tail Scared Off

When a hawk is about to capture a songbird, the songbird has one last trick: a fright molt. It’s when a bird loses feathers due to sudden stress. This usually involves feathers near the tail or rump, where they’re most likely to be attacked as they flee. It can be a saving grace when the bird is about to be caught — similar to a lizard dropping its tail. There’s a downside to having your tail scared off. A tail helps the bird turn and balance in flight. But if dropping feathers lets the bird live to chirp another day, it’s worth it.More info and transcript at BirdNote.org. Want more BirdNote?
