They have hollow bones.
Bird bones are lightweight due to the presence of air cavities within them, known as pneumatic bones. These hollow spaces reduce the overall density of the bones while maintaining their strength, allowing birds to fly more efficiently. Additionally, the arrangement of bone structure in birds is highly optimized for strength and minimal weight, contributing to their lightweight nature.
They are light enough and have wings.
they are light weight and have wings.
Birds have hollow bones, and that makes them light enough for their wings to lift them off the ground. Also they have wings and lots of feathers, and they are shaped to give the bird lift so it can fly.
All birds that are light and have feathers and have a purpose to fly
Because of their wings that makes them fly longer than other birds
The bird's feathers are light. So the wind helps them fly but the bent edge on the wing makes them soar.
Birds have hollow bones that make them lighter so they can fly more easily.
Birds bones are hollow. That is why they can fly, because they are so light because of their hollow bones. x)
To say that birds use wings and feathers to fly, so all birds can fly, would be false. Not all birds can fly. An ostrich is an example of a bird that cannot fly.
Yes, it makes them lighter so they are able to fly easier.
It makes them lighter and so it is easier to fly.
