it makes it lighter so it can fly easier penguins don't have have hollow wings and cant fly but they can swim better because they are less buoyant.
there is more space between the bones so they can fly
it doesn't the lighter their wings are the easier they can fly
Yes, it makes them lighter so they are able to fly easier.
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! (:
i guess it could be in the way that birds have hollow bones
Cheetahs do not have hollow bones. Birds have some hollow bones with criss-crossing segments for strength. This lightens them for flight.
no i don't think so only birds have hollow bones as an adaptation to flight
Flight requires that the weight of the bird be kept as low as possible.
Yes as birds with hollow bones cannot fly for longer whereas penguins do not have hollow bones and are able to swim in rough tides for ages. Also non-hollow bones are stronger and tougher than hollow bones.
Birds have some bones in their bodies that are "hollow." These are called pneumatic bones, and they help birds breathe when they are in flight. The bones of the pelvic girdle, some ribs, the humeru,s and the femur all are pneumatic.
yes they can becasue if the bones are hollw they cant fly
They are not hollow exactly, more honey-comb. This makes for less weight, essential to flight.
