Question

what is the importance of flight muscle in birds?​

Answer 1

Explanation:

We have a large, prominent breast muscle, called the pectoralis major, that originates along the breastbone, or sternum, and inserts near the head of the upper arm bone (the humerus). When the breast muscle contracts, it brings the arm close to the body. (The motion is like a bird's downstroke.)
