BirdNote ·

2025/07/18

Many birds have an excellent sense of smell. And the odors that birds make can act as mating signals for some species. The source for many of these scents, says biologist Danielle Whittaker, are the microbes that live in birds’ preen oil, which they use to keep their feathers in good condition

BirdNote ·

2025/07/14

The song Tico-Tico no Fuba, like Carmen Miranda, came to us from Brazil. Believe it or not, the song is about a bird.

BirdNote ·

2025/07/13

A bird’s bill is an incredible multi-tool — good for preening feathers, building a nest, self-defense, scratching, displaying, building a nest, and egg-turning. And a bill must be the right size and shape for the bird’s diet, whether that’s probing for worms, cracking open seeds, or tearing apart

BirdNote ·

2025/07/12

Birds of the same species don’t always sing exactly the same as each other. But those that live near each other sometimes have similar songs. Scientists refer to this pattern as a song neighborhood. It’s less like a regional dialect among people that’s found over a large area. It’s more local than
