Why do some species of birds-of-paradise have such eye-catching plumage?
If you load a plane that can hold up to 2,000 pounds with more than 2,000 pounds of birds, will it still be able to take off?
Do birds have teeth? Not anymore, but they once did, when they were more similar to dinosaurs.
During migration, birds' digestive system partially shuts down to conserve energy for flight.
Birds use infrasounds to sense storms long before dark clouds gather.
Birds and many reptiles evolved a specialized way of breathing—one-way air flow.
Birds of a feather steal together (and suspiciously hide food from one another).
In addition to hearing your voice, babies also rely on non-verbal communication to learn how to talk.
Birds' flight patterns are expanding due to climate change, which could upset fragile ecosystems.
