Modern birds capable of flight all have a specialized wing structure called the propatagium without which they could not fly. The evolutionary origin of this structure has remained a mystery, but new ...

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 ...

Even the giant wings of the albatross are not "optimally" shaped for their extraordinary long-distance migrations, according to new University of Bristol research. The study, published in Nature ...

When most people think of wings, they immediately think of flight. After all, wings are nature’s ultimate symbol of freedom, allowing birds to soar through the skies and insects to zip through the air ...

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 ...
