Mostly the raptors, hawks, eagles, vultures and I think the owls.
No, insects and bats have wings and neither of them are birds.
Birds have two legs with wings and bills.
All birds have wings. It's just that some of them are useless for flight. The New Zealand kiwi certainly has wings, though it appears to have none. The wings are small and rudimentary, hidden under the kiwis' hairy feathers, but certainly present. The kiwi is a member of the ratite family, a family of birds characterised for being flightless.
yes. Birds are the only animals on earth that have feathers covering their bodies. They are also a vertebrae animal, which means they have a spine.
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
Because their wings aren't strong enough
Airplane designers have been influenced by the study of birds through examining the different qualities of their wings. The strong bones of the birds that are very light help determine the necessary weight restrictions and alloys used in wings. The shape of the wings of birds shows them how to shape airplane wings for maximum lift.
by running and jumping off the ground, also by flapping their wings -Although SOME birds (like the Albatross) have a hard time flapping, THEY HAVE TO WAIT for a strong breeze. Airplanes' wings are thicker at the front of the wing than at the back of the wing. This is in imitation of birds' wings.
The chest wings in birds serve the function of enabling flight and providing stability during flight. They are characterized by being lightweight, strong, and flexible, allowing birds to maneuver and glide efficiently in the air.
Birds have feathers, wings, and strong yet lightweight bones which help them fly. Their unique skeletal structure allows for efficient flight by reducing overall weight while maintaining strength.
Yes. Takahe are birds, and all birds have wings. Even flightless birds have wings, though they are of little or no use.
No, birds have lungs in their chest cavity not their wings.
Bird bodies are made to fly. They have light bones, strong legs, and specially shaped wings. Flying helps birds get away from animals that want to eat them, and makes them better hunters, too. Flying also helps them travel from cold places to warm places, called migration.
Most birds have hollow bones. They are still strong, but lighter in weight.
it is protected since there are they have specials wings called flarimonglous flaps. they are extremply strong wings that protect them for being injured when falling ( moa birds usally clutches ) and since wings are so stong baby moa birds can take a ride on the mamas wings when tryings to escape a pray
Two, all birds have two wings.
they flap wings
