Bird wing shape -- a proxy for long-distance flying ability, or dispersal -- is a trait that influences biodiversity patterns on islands around the world, according to biologists. You can know a lot ...

For centuries, scientists have observed that animals in warmer climates have longer limbs—a pattern known as Allen's Rule. Long attributed to the need to maintain body temperature, the precise ...

You can know a lot of things about birds just by the shape of their wings. A seafaring albatross, stretching out its sail-like airfoils, lives a very different life from a ground-dwelling antpitta ...

Bird physiology is conducive to flight: small size, hollow bones, and generally symmetrical feathers on the wings and tail. It seems like a no-brainer that bird evolution was optimized for flight, but ...

Scientists have compared the relationship among the strength of flight bones, body mass, and the way modern birds fly to better understand the evolution of flight in birds and extinct animals, such as ...

“Awkward” would probably be the most benevolent word I could use to describe the explosive launch into flight of the California quail. Certainly, the words graceful or athletic do not come to mind. A ...
