because they are tiney birds
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 manouvaroble as they are now. their bones are also linked to the lungs, scientific research shows that if a birds windpipe is blocked but a hole in one of its bones is made then it will be able to breath quite normally
only birds that fly have hallow bones they have hallow bone so they can fly True, but there are exceptions to this- some 'table birds' (i.e. ducks, geese, game birds etc.) have solid bones, but they fly also. Flightless Birds usually have solid bones, because they don't need to have body-frames that are as light as possible- the chicken, for example.
They are not hollow like a straw, but they do have larger spaces in them than other animals and humans. Something like a sponge.
Because if they had bones like humans they would be to heavy and they would fall to the ground.
They are not hollow like straws but have many open spaces in them. Something like Swiss cheese but on a much smaller scale. This make them light enough to fly.
Birds' bones are hollow to help them fly. It makes them lighter.
It keeps their weight down, and is a very sturdy shape, stronger in many cases than solid bone.
no they do not have hollow bones. this is because they are flightless and god just made them that way♥ ♥

Birds bones are hollow. That is why they can fly, because they are so light because of their hollow bones. x)

Birds are the only creatures that are warm blooded and have wings. Not all birds, however, have hollow bones - most flightless birds do not have hollow bones.
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.
Cheetahs do not have hollow bones. Birds have some hollow bones with criss-crossing segments for strength. This lightens them for flight.
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly.
Coral, jellyfish, and aneomes are hollow bodied animals
i guess it could be in the way that birds have hollow bones
