It's light, streamlined so has low resistance to air. Also light-weight bones with air holes in them which are connected to the lungs.
No it makes them fly
Solid Bones A+
i guess it could be in the way that birds have hollow bones
Birds have a number of traits that make them lighter, an adaptation for flight. The mait trait that makes birds lighter is that their bones are hollow.
No, humans do not have hollow bones. Hollow bones are typically found in birds and are adaptations for flight, providing strength with reduced weight. Humans have a different bone structure that is denser and stronger to support our body weight.
No, birds' bones are not necessarily weak. In fact, bird bones are often designed to be hollow or semi-hollow, which makes them lightweight yet strong enough to support flight. This adaptation allows birds to be agile and fly efficiently.
Adaptation is when a species develops or adjusts to a niche in the environment.
Hollow bones in birds are an adaptation for flight because they reduce the overall weight of the bird, making it easier for them to take off and stay airborne. The air-filled cavities within the bones also provide structural strength and help to support the stresses of flying.
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.
This example demonstrates adaptation, as birds have evolved hollow bones to enhance their ability to fly, which is critical for survival.
Birds have hollow bones to help them fly. Solid bones would add to much weight and make it impossible to fly.
Adaptation feature of a bird with respect to bones:- light weight because of HOLLOW BONES along with reduction in the number of bones.
