Question

what have small birds to do to stay in the air​

Answer 1

Explanation:

because flapping birds have smaller wings than soaring birds, they must move forward faster to stay in the air. Most songbirds must fly at least 11 miles per hour to stay up. One scientist calculated that for an ostrich to stay aloft, it would have to take off and maintain a minimum speed of 100 miles per hour.
