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 ...

Birds in V-shaped formations save energy by adjusting wing flapping and timing. A new study reveals birds reduce flapping ...

Climate change is shrinking our birds. Birds in both North and South America are getting smaller as the planet warms, and the smallest-bodied species are changing the fastest, a study reported Monday.

ITHACA, N.Y. -- Butterfly wing patterns have a basic plan to them, which is manipulated by non-coding regulatory DNA to create the diversity of wings seen in different species, according to new ...
