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 supracoracoideus is the second largest and is the primary elevator and supinator. In addition, there are distal wing muscles that assist the bird in flight. [5] Prior to their existence on birds, feathers were present on the bodies of many dinosaur species.

It has limbs and structures that mimic the hip, ankle and foot of a bird, while being less complex compared to the multisegmented avian anatomy. In tests, Raven jumped into take-off just like a ...
