They are hollow (for lightness) and have air sacks connected to the lungs (this makes the lungs more efficient).
Birds have hollow bones to help them fly.
No, they do not.
200 because there are abut 200 bones in the skeletal system. and it gives support to your body
Birds bones are hollow. That is why they can fly, because they are so light because of their hollow bones. x)
no they do not have hollow bones. this is because they are flightless and god just made them that way♥ ♥
i guess it could be in the way that birds have hollow bones
Yes, parrots have bones. All birds have bones.
Most birds -- and all birds that fly -- have semi-hollow bones. Most reptiles, however, do not.
regular bird bones
Birds have pneumatic bones.
Birds are the only creatures that are warm blooded and have wings. Not all birds, however, have hollow bones - most flightless birds do not have hollow bones.
their bones are hollow to make them lighter, and more legible for flight. if they had solid bones they wouldn't be able to fly as fast, high or as maneuverable as they are now. Hope this helped! (:
