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.
In bird anatomy, the gape is the interior of the open mouth of a bird, and the gape flange is the region where the two mandibles join together at the base of the beak. [33] The width of the gape can be a factor in the choice of food. [34] The gape flange on this juvenile house sparrow is the yellowish region at the base of the beak.

Cooperative breeding, where birds other than the breeding pair help raise the young and is common in some bird families, is extremely rare in parrots, and has only unambiguously been demonstrated in the El Oro parakeet and the golden parakeet (which may also exhibit polygamous, or group breeding, behaviour with multiple females contributing to ...
The tawny frogmouth was first described in 1801 by the English naturalist John Latham. [4] Its specific epithet is derived from Latin strix 'owl' and oides 'form'. Tawny frogmouths belong to the frogmouth genus Podargus, which includes the two other species of frogmouths found within Australia, the marbled frogmouth and the Papuan frogmouth. [5]
