Both humans and birds * have bony skeletons * are omnivorous * can vocalise
and * are available in a range of colours :-)
They are hollow and many are connected to the lungs to get more air through the birds body.
They are similar in that both are bones.
Bird bones are partially hollow and are much lighter. This helps them to fly.
Scientists infer they both come from a common ancestor.
In order for the bird to be as light as possible for flight. This "hollowness" reduces their body weight by about 5%, depending on what kind of bird it is, in contrast to their would-be weight if their bones were not hollow.
Tobi says: Bird's bones are hollow to help them fly,obviously to reduce weight when they fly. Human bones, on the other hand, are not hollow. We need strong bones to do the things we do, eg: walking, skipping, jumping etc...
both wings have a lot of bones and humans dont have wings
Ptarmigans, like many flying birds, have hollow bones. These light bones make it easier for the bird to fly. During the summer, the ptarmigans bones become heavier and stronger so they can withstand the stress of the ptarmigan's search for food. in the winter the bones become lighter so the bird can conserve energy while flying.
There are 159 bones in a frog skeleton, depending on what type of frog.
They are hollow and light.
bird bones are lighter
Bird bones because feathers are very light and the bones just depend on the type of bird.
Bird Bones in the Bughouse was created in 2004-10.
regular bird bones
The kiwi is a bird and has a spine (backbone).
Human bones are thicker and denser; bird bones are thinner, hollow and mean less weight on the bird.
Birds do have bones.
No, bird bones are hollow.
there are bones for birds and my bird LOVES them!

the bones are hollow. makes the bird a lot lighter and thus generally suited to take flight!
