Their bones are hollow which makes the bird light. With its lightness it is able to fly.
All have adaptations to some extent. However in some cases they are insufficient to allow flight. Ostriches cannot fly for instance, though they have wings. It can be argued that penguins 'fly' under water.
That would be their wings
Adapted bones in birds are lightweight and strong, aiding in flight by reducing overall body weight. Feathers provide lift and propulsion, helping birds generate the necessary lift force and thrust to stay aloft. Together, these adaptations allow birds to fly efficiently and effectively.
Very light bodies.
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.
Cute question! Birds like to get high. Feathers allow birds to fly.
birds have hollow bones and light feathers that make them able to fly flap and glide, dont you wish you could fly?
sit around and eat cheese sticks
Wings, feathers, and light bones.
It is not only birds that fly. Bats fly and they are not birds.
arrgoant messanger god that had magic sandals to allow him to fly
Hollow bones, curved wings to make them aerodynamic and light feathers to make them almost weightless.
