Question

three adaptations which help birds to fly​

Answer 1

Answer:

Many of a bird's bones are less dense than human bones, which makes birds' bodies lightweight. Flying birds have large chest muscles that move the wings. Birds have feathers that help them fly. The long flight feathers on the wings and tail help birds balance and steer.
