Understand that a streamlined body shape achieves a greater speed. A streamlined body shape is one that is narrow at both ends, and broad in the middle. This shape enables the animals to fly faster. Streamlined body shape Just like there is water resistance, there is a force called air resistance that opposes motion in air. When a bird is flying, its streamlined body shape helps to reduce air resistance

How ae bird bones different from those other animals?
Tobi says: Bird's bones are hollow to help them fly,obviously to reduce weight when they fly. Human bones, on the other hand, are not hollow. We need strong bones to do the things we do, eg: walking, skipping, jumping etc...
Why does a bird have compact bones?
In order for the bird to be as light as possible for flight. This "hollowness" reduces their body weight by about 5%, depending on what kind of bird it is, in contrast to their would-be weight if their bones were not hollow.
Which part of the body does a bird use most for movement?
The "lift" is from the wing movement, but the real ability for a bird to fly is the fact that their bones are hollow and this makes them much lighter so that they can get lift-off.
What adaptation helps birds fly?
Some energy source is required to overcome the unavoidable drag of pushing through the air, to lift the bird or airplane up to flying height, and to give the bird or airplane kinetic energy. Airplanes use propellers or jet engines. Birds use strong muscles in their breasts to flap their wings. In addition, bird wings are hinged, while airplane wings are riged and fixed. The bird uses its strong muscles to push its wings downwards, pushing air downwards, generating lift, and, if the wings are angled properly, also thrust. The big problem then becomes not pushing air back upwards when the bird moves its wings up for the return stroke. They have no teeth and hollow bones
Description of a bird?
The bird has body is covered in feathers, the bones are very light. It has a wishbone and wings. The bird also has sharp claws as fingers. A bird can be different sizes.

What weighs more bird feathers or bird bones?
Bird bones because feathers are very light and the bones just depend on the type of bird.
Do the feathers of a pigeon weigh less than the bones of a pigeon?
yes, for many flying birds, including the pigeon, the bones are filled with air sacks and hollow and are actually lighter than the feathers that cover the body ... other example is the humming bird.
How does body shape and structure help insects fly?
They have hollow and very light bones, plus the lift from thier wings then they are beating both together give the bird the ability to fly
How heavy are bird bones?
Most bird bones are very light, because extra weight would make it impossible to fly.
How do birds bones enable then to fly?
The bones in a bird are hollow, making the bird lighter, allowing flight. However, this also has a downside: bird's bones are very easily broken, and once they are broken they often do not mend properly, meaning that if a bird breaks its wing, it will often never fly again.
How does hollow bones help birds fly?
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.
