Bird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly.

The furcula (Latin for "little fork"; pl.: furculae) or wishbone is a forked bone found in most birds and some species of non-avian dinosaurs, and is formed by the fusion of the two clavicles. [1] In birds, its primary function is in the strengthening of the thoracic skeleton to withstand the rigors of flight.
The skeleton of a bird wing. Places of attachment of various groups of flight feathers are indicated. The mute swan with outstretched wings Wing of the white-tailed eagle. Bird wings are a paired forelimb in birds. The wings give the birds the ability to fly, creating lift. Terrestrial flightless birds have reduced wings or none at all (for ...
Most birds have four toes, typically three facing forward and one pointing backward. [7] [10] [8] In a typical perching bird, they consist respectively of 3, 4, 5 and 2 phalanges. [2] Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet while the ostrich have only two toes (didactyl feet).
Brains of an emu, a kiwi, a barn owl, and a pigeon, with visual processing areas labelled. The avian brain is the central organ of the nervous system in birds. Birds possess large, complex brains, which process, integrate, and coordinate information received from the environment and make decisions on how to respond with the rest of the body.

This stylised bird skeleton highlights the keel bone. A keel or carina (pl.: carinae) in bird anatomy is an extension of the sternum (breastbone) which runs axially along the midline of the sternum and extends outward, perpendicular to the plane of the ribs.
