Question

birds and their wingspan

Answer 1

Answer:

Birds are a group of warm-blooded vertebrates constituting the class Aves, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.

Wingspan and wing shape are physical adaptations that affect how a bird flies. Long, narrow wings are stable in the air and help a bird to fly long distances at steady speed. Short, broad wings give birds the ability to quickly change direction.
