i guess it could be in the way that birds have hollow bones
No it makes them fly
Solid Bones A+
their bones are hollow to make them lighter, and more legible for flight. if they had solid bones they wouldn't be able to fly as fast, high or as maneuverable as they are now. Hope this helped! (:
they are hollow to be more aerodynamic
It is said that birds have no marrow in their bones, which allows them to be lighter for flight. This is partially true... The major reductions in weight however comes from the lack of large jaw bones, no teeth because no jaw bones, small skull, and very little tail [bone]. There is no marrow in the bones of birds, but this doesn't make them lighter it makes the bones stronger. My source (look under "The Bird Skeleton"): http://www.earthlife.net/birds/anatomy.html#4 In addition to the above, some birds' respiratory systems circulate air through some of the bones in order to complete the respiratory circuit. Birds do not breathe in and out like mammals. Their lungs act like a bellows to move the air in through their mouth and out through their nostrils. This permits a much greater oxygen flow, which in turn allows their muscles to create the high energy levels needed for flight.
So that the bird is not too heavy to fly and to aid in the intake of oxygen as the bird breaths in flight.
Birds have hollow bones. (Except for penguins, which now have solid bones to help them dive)
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly. They have crisscross structures to add support inside the bones.

because they are tiney birds
Bird bones are hollow and very thin or at least most of them are. Some are air filled and others have trusses or cross walls to make them strong. They also have fewer bones than mammals or reptiles of similar size. The skeleton is more rigid. These are factors which help a bird to manage flight.
