Answer to Question #143030 in Zoology for RamC

Question

Discuss all the skeletal modifications found that make flight possible for birds.

Answer 1

The bird skeleton is extremely lightweight, but strong enough to withstand the stresses that a bird experiences when taking off, flying, and landing. The bird's hollow bones make the skeleton lighter for flying, and allow more oxygen to be absorbed from the air into the blood for that extra energy a bird needs.
