It's light, streamlined so has low resistance to air. Also light-weight bones with air holes in them which are connected to the lungs.
its an adaption to flight cause' a birds bones r filled with air and are EXTREMLY LEIGHT like a feather so that they can fly easily and quikly without being weighed down by their bones
Yes, they have much thinner and lighter bones. That makes them better for flying.
No it makes them fly
Solid Bones A+
i guess it could be in the way that birds have hollow bones
no i don't think so only birds have hollow bones as an adaptation to flight
Birds have a number of traits that make them lighter, an adaptation for flight. The mait trait that makes birds lighter is that their bones are hollow.
Adaptation is when a species develops or adjusts to a niche in the environment.
Among other adaptations, birds have hollow bones to make for a very light skeleton, a large breastbone to attach flight muscles, and strong muscles in their chests for flight.
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.
Adaptation feature of a bird with respect to bones:- light weight because of HOLLOW BONES along with reduction in the number of bones.
Aerial adaptation is also known as volant adaptation. The main features are wings. They also have hollow bones. Examples are the adaptations in birds and bats.
there is more space between the bones so they can fly
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! (:
