They are classified as a bird because they have feathers, wings, are warm-blooded, lay eggs, and have an internal skeletal system.
skeletal and muscle system!
they all work together and help the bird fly because a birds lungs connect to the air sacs that provide a constant supply of oxygen to the blood and make the bird more lightweight.
The bird's wing is most similar to a human arm because both structures have a similar skeletal layout with long bones (humerus, radius, and ulna in humans; humerus, radius, and ulna in birds) supporting the limb and connected by joints. The bird's wing, however, is modified with feathers for flight.
A bird has a lightweight skeleton made mostly of thin and hollow bones filled with air sacs to aid in flight. This type of skeletal structure is called pneumatic or avian skeletal structure.
because his mom isis was a bird and osirus was human so he was part human and bird.
A bird's digetive system is different because a bird has a gizzard unlike a human, in the gizzard are rocks and pebble to help make the food smaller ,because the bird may not be able to chew it's food up completely.
The dodo bird was a bird that could not fly and it is now extinct. This birds closest living relative is a pigeon and their skeletal features were almost identical to that of the pigeon.
