Designed For Flight. • Lightweight beaks and skulls.
Designed For Flight. • A nearly rigid backbone that gives a solid support for the strenuous muscle activity required for flying
Designed For Flight. • Hollow spaces in the skeleton that provide room for air sacs, which contribute to the efficiency of the respiratory system and make the bird lighter.
Designed For Flight. • Bipedal (“two-footed”) anatomy, which leaves the wings free for flying.
