even though the bird is smaller than its wings, it doesn't mean it weights less then the wings, it weights more than the wings, but the main reason for its flight, is from its bones; the bones are hollow, compared to a human bone, which its filled with a spongy liquidy solid or a non-newtonian fluid called bone marrow. If we had hallow bones like birds, we could jump really high up in the air. The wings cause an updraft to just "hover" or "propel" itself through the air, the wings are what causes it to move around and change direction. The bones, are what help it stay in the air, and lift off. We can't do that because of our bones, but birds can.

∙ 12y agoBirds have been designed for flying in many of ways. It's actually quite amazing when you think of it. Their bone structure is hollow, which is lighter then compact bones like ours. their contour feathers work like the wings of a plain, making the air push over and under it to stay gliding. their beaks make them more aerodynamic while their air sacks work as another set of lungs. That way they always have air while flying high in the air where oxygen isn't as plentiful. Their tails and wings work as a steering mechanism. If they tip their left wing down, they go down in a circular motion. Birds also have hardly any body fat. It's all mussel. Birds like humming birds have to constantly eat. Their body burns so many calories because of their constant flapping of their wings. It's instinctive that geese fly south, they weren't taught. Some birds like eagles are known to dive bomb in a body of water for fish. Instead of falling into the water, their wings work as a parachute, the air pushing against the wings to cushion the speed on their decent. They size of their wings also help. Ostriches can't fly because of the length of their wings, the way their feathers are, and because they're too heavy. Their feathers are more like down and don't catch the wind. If you make a contour feather and a down feather drop at the same time, and down will fall much quicker because contour feathers have something called Barbs. They act as a zipper to keep the parts of the feather to stick to each other. The down doesn't have that and just falls.
Scientists are looking to birds for new technology of plains so make them more efficient, and burn less fuel.
Hope this helped.

∙ 12y agoThe skeleton of a bird is adapted for flight because many bones are hollow, making the bird lightweight. Flying birds have chest muscles that move the wings. Finally, feathers help the bird fly. In addition, the bones of a bird's forelimbs form wings.

How do birds use their tails in flight?
To stabilize their flight.
What three adaptations do birds have for flight?
Their forelimbs have become modified into wings for flying. All modern birds evolved from ancestors that could fly. Some modern birds, like penguins and ostriches, don't fly today. But they still have feathers and wings. Feathers probably evolved from reptiles' scales. Both feathers and scales are made of the same tough material as your fingernails. Birds' feet and legs have scales on them. 2 The bodies of birds are adapted for flying. Many of a bird's bones are hollow which makes birds' bodies lightweight. Flying birds have large chest muscles that move the wings. Birds have feathers that help them fly. The long flight feathers on the wings and tail help birds balance and steer. In addition, birds have a system of air sacs in their body that connect to the lungs. The air sacs enable birds to extract much more oxygen from each breath of air than other animals can. Birds need extra oxygen to release large amounts of energy to power their flight. Their four-chambered heart also helps a bird get more oxygen. The advantage of a four-chambered heart is that there is no mixing of oxygen-rich and oxygen-poor blood. Blood that arrives in the bird's body tissues has plenty of oxygen. 3 Birds also have well-developed brains and keen eyesight. In order to fly, birds must have very quick reactions. When approaching a tree or cliff, a bird has only a few seconds to spot a place to land safely and avoid crashing. Most birds have keener eyesight than humans do. Birds' eyes are much larger in relation to their body size than humans' eyes.
What other groups of animals fly?
flight refers to a group of flying birds, ie a flight of swallows
What are a birds feet most adapted to?
swim easily through the water.
How have birds adapted to be able to fly long distances?
Some birds, such as ducks, have webbed feet to propel themselves through the water. Others, such as penguins, are highly adapted for swimming in the water and can use their wings as paddles (at the price that their wings are useless for flight).
How have birds' tails adapted for flight?
A birds tail swerves its body left and right. It also has drag.
How are birds adapted to flight?
cause without there wings they would get captured by preadetors
How do birds' bodies become adapted to the demands of flight?

How have birds lungs adapted for flight?
yes, as well as a hollow bone structure
What is the function of birds tail?
the function of a tail is to lift its body and to increase the speed of flight
What are 5 reasons birds adapted for flight?
Survival, Food, Competition with ground animals, have their nests higher up, and to spot that booty from afar. That booty is righteous.
Does a birds' leg structure have anything to do with its flight?
Yes. It helps by tucking into the birds body. Inside their legs and feet is a structure to help them fly.

How is a birds heart adapted for flight?
It has a fast heart- rate that gets plenty of oxygen. Rich blood gets to the muscles
