Detailed explanation-1: -The wings are the bony parts of the forelimbs that help to fly in the air. They have strong shoulder bones and large breastbones because these bones control the muscles during the flight.

Detailed explanation-2: -Hollow bones are also called pneumatized bones, meaning they’re filled with space for air. It is thought that this structure helps with oxygen intake during flight. Air sacs are attached to the hollow areas in a bird’s bones. Essentially, their lungs extend throughout their bones.

Detailed explanation-3: -Birds fly by flapping their wings, steering mainly with their tails. Compared to the parts of an airplane, a bird’s wing acts as both wing and propeller. The basal part of the wing supplies most of the supporting surface, the wing tip most of the propelling force.
