Bird bones are light because they are hollow.
A bird's bones are virtually hollow so that they are light weight so the birds can fly. Other animals, including humans, have more marrow in our bones and they are very heavy compared to bird bones.
Bird bones because feathers are very light and the bones just depend on the type of bird.
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
Most bird bones are very light, because extra weight would make it impossible to fly.
It's body is light as a bird's bones are light so that they can fly. If the bones are heavy like us it cannot fly.
They don't, bird bones are very light and airy due to their porousness. Helps them fly. Though, penguins and ostriches and the like do have sturdy bones, for obvious reasons. Those bones are derived from standard airy bird bones though.
Birds' wings have hollow bones and feathers; our arms don't. Also, the musculature and location of the bones is very different.
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.
Normal birds have very light, hollow, fragile bones to save weight making flight easier. Penguins however have solid heavy bones. Not only does this improve bone strength, but also adds weight to aid in diving and swimming.
Yes very !
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.
It wings. It also has very light bones compared to other animals of its size, allowing it to fly easier
Birds' bones are hollow to help them fly. It makes them lighter.
Wings , hollow bones. Feathers are very important also.
Birds have hollow bones and very large breasts
The bones in a bird are unlike other animals in that they're hollow, meaning they weigh much less for their size than other animals. Also, the feathers on the birds body, also very light, help capture wind better than fur can, for example, promoting flight.
It uses its curved wings. The whole of a bird's body structure makes it very light. It also loses its weight by pooing almost everytime. So it will be lighter and is able to fly more easily. Some birds' body structures are already too big and they cannot fly. Well the reason birds CAN fly is because they have hollow bones. There hollow bones makes them lighter. They also have a KEEL bone which is used to keep the bird upright so they don't fall over during flight. and pooing doesnt make any difference with the birds weight!!
Your dog will be very happy to be able to chew on a pork shoulder bone. That kind of bone is solid enough that it will not splinter. The dangerous bones are chicken or other bird bones, because they are hollow and can splinter, creating sharp fragments that can harm a dog.
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. Good eyesight and a sharp beak. It can also glide short distances and is warm blooded. And has a back bone and tiny feet with sharp claws.
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.
Birds are very light because of their thin bones made convenient for flying. I forget if Big Bird can fly, but if he can, I would estimate about 83 pounds, considering the size of his build. If he can't fly, I estimate about 143 pounds.
Our bones would be very weak and we would break them easily

The type of muscles that wrap around bones are typically skeletal muscles, but muscles do not make the bones light. What makes bones light are the fact that they are porous. There are a lot of holes within the bones that make it lighter, but those holes make sort of arcs and what not, similar to those in the Eiffel tower, for example. They are light weight, but very strong.
