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.
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly.
because they dont weight much
yes
Birds use convection by using convection currents the heat will rise as a draft and then birds can ride the draft to reach higher altitudes.
Water pollution depending on what it is an have several different effects. I do not have much time so a simple answer is this. Oil affects birds by clinging to their feathers and causing them to lose their flying ability, and it destroyes the protective oild on their feathers.
The difference between the troposphere and the thermosphere is the troposphere is the second layer of the atmosphere where all of the birds hot air balloons and airplanes fly. The Thermosphere is the third layer of the atmosphere where their is less oxygen.
Hydrogen is used in weather balloons because they are very light which help the balloon to float or fly easily.

birds have hollow bones to help them 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! (:

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.
Birds bones are hollow. That is why they can fly, because they are so light because of their hollow bones. x)
birds fly into space due to their hollow bones
The phylum that has the adaptive feature of pneumatic bones is Chordata. Pneumatic bones are lightweight structures filled with air that help reduce the weight of the skeleton, making it easier for organisms to fly or swim, such as in birds.
hollow bones and feathers help
Hollow bones is just one of the advantages birds have gained through evolution which makes them light. A light body allows them to fly faster, using less energy.
Birds can fly because they have wings, and also because they have hollow bones. Humans can't fly because we don't have hollow bones or wings! Because a Birds bones are hollow my science teacher also calls there bones spongy because they look like that from the inside. And since there bones are hollow it makes them less heavy i would guess and thats why they can fly!!!
