In order to maintain the rigidness necessary for flight the birds collar bones have fused together making a "wishbone" of sorts. The rigidness and hollowness of the bones make flight easier on the bird.
Soft, downy feathers keep birds' bodies toasty and warm. At the same time, the waxy outer ones keep off the rain. More importantly, feathers allow birds to fly. Birds beat their feathered wings to lift off the ground and fly through the air.
There is no such thing as a dinosaur that flys. The difference between a pteradoctyl and a bird is: Birds have feathers and pteradoctyl's don't. The difference between a oviraptor and a bird is: Oviraptor have hands and birds have wings.
Birds can fly as they are light and have hollow bone. They also have wings that can propell themselves off the ground. Humans are simply to heavy and have the wrong bone structure for flying and obviously we don't have wings!
Penguins do not have skeletons that are identical to humans certain things are different such as bone length and the presence of a tail in the penguin. But certain structures are referred to as homologous. example: the flipper in the penguin and the arm and hand of a human have the same bone structure just different bone lengths.
Yes, birds with long legs can fly. The only bird with long legs that cant fly is the Ostrich. The only problem is that because of their long legs they are so used to walking, so they don't fly as well as other birds.
because it helps it begum more helpful to make it fly most of the holler bone is made out of little little bone........@
It's wings and the bone structure in them help the eagle, and all birds actually, to fly.
Type your answer here... sternum is like a bone of wings which helps the birds to fly
Birds can fly because they light feathers &they do not have bone marrow
Birds that fly.
Birds cannot fly at all without their feathers.
No
Birds have hollow bones to help them fly.
There is a distinct difference. I believe I can fly, and birds just fly. :) Just kidding. People fly with 200 ton contraptions of metal and fire, while birds fly with 2 limbs of feather, skin, bone, and muscle. See the difference?
Without wings, birds couldn't fly.
they are light enough to fly
the tail has flight feathers and the flight feathers help a bird to fly.
