Class Aves
The endoskeleton of birds is fully ossified and the long bones are pneumatic, which means they are hollow with air spaces. This is an adaptation for flight, as it reduces the weight of the bird's skeleton without sacrificing strength. The bones are also fused together in some areas to provide additional strength and stability.
Birds also have several other adaptations for flight, such as:
Feathers: Birds are the only animals with feathers, which are lightweight yet strong and provide lift and maneuverability in the air.
Wings: The forelimbs of birds are modified into wings, which are powered by strong chest muscles.
Air sacs: Birds have a unique respiratory system with air sacs that allow for continuous airflow through the lungs, providing the high oxygen levels needed for sustained flight.
Lightweight body: Birds have a streamlined body shape and lightweight bones, which further reduce weight and drag during flight.
Overall, the avian skeleton is a highly specialized adaptation for flight, providing birds with the ability to soar through the skies with ease and efficiency.

Pneumatic bones have hollow cavity and are characteristic of birds. In birds, endoskeleton is fully ossified and the long bones are hollow with air cavities to reduce weight which aids in flight.
