Question

what are the adaptations found in class aves

Answer 1

Hey Buddy.
Here is your answer.

1. Birds have short body with compact bones. This reduces the weight of the body and makes it light.
2. There are different kinds of feathers present in birds: outline feather helps to decrease the drag of the body by making it streamlines; primary feathers helps to provide shape to the wings and make the flight possible; tail feather are used as rudder for balance of the body.
3. Bones in birds are either hollow or fused to reduce the weight of the body. The fusion of caudal bone to form pygostyle and hollow bones of skull are good example of it.
4. Absence of teeth and present of beak is also one of the important adaptations for flight in birds.
5. Forelimbs are modified into wings and hence aerodynamics in shape. They are also close to the centre of gravity.
