Animals that have both legs and wings are birds. Others with these are not animals and are called insects.
humming birds
A flying bird's wing is in the shape of an airfoil.
Without wings, birds couldn't fly.
the birds wing is hairy and the insects wing is delicate
when bats sleep there wing will grow back.
An example of an analogous structure is the wings of birds and the wings of bats. Both structures have a similar function (flying) but are made of different materials and have evolved separately in these two distinct groups of animals.
Homologous characteristics (as opposed to analogous characteristics, eg a bats wing and a birds wing). So I guess its called homology?
A birds wing looks like a bunch of fethers. take a look for your sellf at bing.com or google and punch in "what dose a birds wing look like" and there you can see.
No. Both the cedar and bohemian waxwings are common birds.
Although bats and birds are both vertebrates, they evolved flight separately. Bats move the air with thin skin rather than feathers. And the bones in bat wings reach the wingtip, while birds have short wing bones and long flight feathers..sorry if i havent answered your questions properly im only 12..:) but hopefully you would have learned something
so they can fly
