Some energy source is required to overcome the unavoidable drag of pushing through the air, to lift the bird or airplane up to flying height, and to give the bird or airplane kinetic energy. Airplanes use propellers or jet engines. Birds use strong muscles in their breasts to flap their wings. In addition, bird wings are hinged, while airplane wings are riged and fixed. The bird uses its strong muscles to push its wings downwards, pushing air downwards, generating lift, and, if the wings are angled properly, also thrust. The big problem then becomes not pushing air back upwards when the bird moves its wings up for the return stroke. They have no teeth and hollow bones

What is the difference between birds that fly and birds that don't fly?

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.


Are birds bones weak?

No, birds' bones are not necessarily weak. In fact, bird bones are often designed to be hollow or semi-hollow, which makes them lightweight yet strong enough to support flight. This adaptation allows birds to be agile and fly efficiently.


Some birds fly south before winter each year this is a example of?

When birds fly south for winter each year, this is known as "migration." The birds fly south to live in a warmer climate, and in the spring they fly north again when the weather changes.


How does this structural adaptation help the animal survive?

The forelimbs of birds are adapted to fly. So they are converted into wings. So there is serious loss of forelimb functions. But then you have to pay the price for everything you get in return. The bones of birds are hollow to large extent and they have air spaces in there body to make it light. So they can fly. The bat is a mammal and do have forelimbs. Here the skin is used as wings. But then again the functions of the forelimbs are adversely affected.


Can long-legged birds fly?

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.
