Skeletal and flight

                The bird’s structure is very different than ours. Their bones are hollow that is what helps them fly.  These are called Air-filed bones. The bones are held up by little crossing bones in the inside it. “ It is easy for a 10 pound bird to have a skeleton of about 10 ounces”.  Even though the these birds are very light there skeleton must be strong enough to hold itself up.  It is strong because all of its bones are tied together as one huge bone.   There powerful breast muscles are a big part in there flying because they are the heaviest part of the bird, is the power wheel to flapping the wings.  If these muscles are not big enough to support the bird then it physically cannot fly.  There designer wings all birds have wings to fit the bird.  They could be long pointed wings like the falcon, swift, or a peregrine that help you fly very consistently, or ground birds like turkey’s, pheasants, or quail with short stubby wings.  Others have long wide wings that help to sore through the sky like Eagles hawks and condors.
