Adaptations for Flight T he evolution of flight has endowed birds with many physical features in addition to wings and feathers. One of the requirements of heavier-than-air flying machines, birds included, is a structure that combines strength and light weight. One way this is accomplished in birds is by the fusion and elimination of some bones and the "pneumatization" hollowing of the remaining ones. Some of the vertebrae and some bones of the pelvic girdle of birds are fused into a single structure, as are some finger and leg bones -- all of which are separate in most vertebrates. And many tail, finger, and leg bones are missing altogether.
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 development of a beak has led to evolution of a specially adapted digestive system. These anatomical specializations have earned birds their own class in the vertebrate phylum. Birds have many bones that are hollow pneumatized with criss-crossing struts or trusses for structural strength. The number of hollow bones varies among species, though large gliding and soaring birds tend to have the most. Respiratory air sacs often form air pockets within the semi-hollow bones of the bird's skeleton.
Suppose you're a whooping crane migrating from the Gulf of Mexico north to Canada. That will be a long flight! The more body weight you have, the harder your trip will be. A whooping crane is one big bird. How does it manage to fly so far with all that "baggage" on board? Actually, a whooping crane is large but lightweight.
Forgot Password? Ask any elementary school student why birds have hollow bones, and they'll have a easy answer for you: it's to help them fly! Gold star, kid. But how do hollow bones really help birds fly? Contrary to popular belief, it's not because it makes them lighter. It's because they need so much oxygen to fly that their lungs actually extend into their bones.
One of the requirements for heavier-than-air flying machines is a structure that combines strength with light weight. This is true for birds as well as planes. Birds have many physical features, besides wings, that work together to enable them to fly. They need lightweight, streamlined, rigid structures for flight. The four forces of flight — weight, lift, drag and thrust — affect the flight of birds. The increased speed over a curved, larger wing area creates a longer path of air.
Birds have hollow bones due to the fact thay need to be as light as possible for their wings to generate enough lift for them to fly. How do the Adaptations Oil coated feathers, Hollow Bones, Streamlines Bodies, and Regulating Body temperature help the particular animal that has.
