Detailed explanation-1: -Birds have light and hollow bones. Most birds are capable of flight with the help of these bones. These hollow bones make their body light which allows them to lift themselves easily.
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.
Detailed explanation-3: -Hollow, air-filled bones lighten the weight of the skeleton. Skeletal adaptations lend strength to the skeleton so that the thrust (forward force) generated by the wings can lead to maximal lift, and the bird can be propelled through the air with minimal compression to the body cavity.
Detailed explanation-4: -Less weight Bird skeletons are surprisingly light for their size due to having hollow bones.
Detailed explanation-5: -Birds have hollow bones, which keep their body light for flight.
