hollow bones and feathers help
There is no such thing as a dinosaur that flys. The difference between a pteradoctyl and a bird is: Birds have feathers and pteradoctyl's don't. The difference between a oviraptor and a bird is: Oviraptor have hands and birds have wings.
No,not all birds that have wings and feathers can fly. An ostrich & peacock can't fly and they both have feathers and wings. Birds like the ones I named have small wings that's why they can't fly. All their muscles are in their legs.

Birds have feathers, which serve multiple functions such as insulation, waterproofing, and aiding in flight. Feathers are a unique feature of birds that help them to maintain body temperature, display colorful patterns during courtship, and enable them to fly.
No, rats cannot fly. They are land mammals and do not have wings that would enable them to fly.
birds have strong chest muscles and lightweight bones, which enables them to fly. Their feathers, too, are lightweight, which helps them fly. During flight the birds feathers compress, giving it a more streamlined shape which helps it fly faster. Flight takes up a lot of energy, and birds must eat up to 30% of their body weight each day.
Birds have there forelimbs modified into wings to fly. The chest muscles has to be very much stronger in birds to enable them to fly. To bear the force of flying, the sternum in birds has be relatively large as compared to human being.
Flightless birds have a small keel and wings.
Bats are not birds because they are mammals as they have the characteristics of a mammal. They have these characteristics which enable them to be classified as mammals. They are warm blooded, and they have fur.

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.
Three distinguishing characteristics of birds are feathers, which provide insulation and enable flight; a beak or bill, adapted for their specific feeding habits; and a lightweight skeletal structure that includes hollow bones, allowing for efficient flight. Additionally, most birds lay hard-shelled eggs, which protect their developing young. These traits collectively enable birds to thrive in a variety of environments.
Birds have wings which help them fly. They have claws that enable them grasp branches firmly. Their beaks enable them to pick up food with ease.
There is no such thing as a dinosaur that flys. The difference between a pteradoctyl and a bird is: Birds have feathers and pteradoctyl's don't. The difference between a oviraptor and a bird is: Oviraptor have hands and birds have wings.
It is not only birds that fly. Bats fly and they are not birds.
Hollow bones, curved wings to make them aerodynamic and light feathers to make them almost weightless.
Ducks fly, lay eggs, have feathers, molt, migrate - all of which are bird characteristics.
