Birds don't always fly over obstacles; sometimes they run over while flapping their wings. Intrigued by this behavior, scientists measured how much energy flap running birds use compared to their ...

A new study into the flight characteristics of condors — the largest soaring birds on Earth — finds that they rarely flap their wings once airborne. Condors are capable of flying for over a hundred ...

(CN) — Engineers from an international research team have developed a new high-tech drone capable of mimicking the calculated yet erratic flying patterns of the swift, one of the most high-speed and ...

Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and ...

How did the earliest birds take wing? Did they fall from trees and learn to flap their forelimbs to avoid crashing? Or did they run along the ground and pump their "arms" to get aloft? The answer is ...
