Answer 1

Answer:

Birds' wings flap with an up-and-down motion. This propels them forward. The entire wingspan has to be at the right angle of attack, which means the wings have to twist (and do so automatically) with each downward stroke to keep aligned with the direction of travel. Birds can fly in various ways.

Answer 2

Answer:

Bird's wings have feathers and strong muscles attached to them. With the help of their strong arm and chest muscles, birds flap their wings and fly. The bodies of birds are very light which help them to fly easily. This is because the bones of birds are thin, light and hollow.
