1. Wings and Feathers
-
Wings generate lift and thrust.
-
Feathers reduce air resistance and help with steering.
2. Lightweight Skeleton
-
Hollow bones make birds light, aiding flight.
3. Strong Muscles
-
Powerful breast muscles (pectorals) allow flapping for takeoff and sustained flight.
4. Aerodynamic Body
-
Streamlined shape reduces drag and allows smooth flight.
Exceptions
Not all birds can fly. Examples of flightless birds:
-
Ostriches
-
Emus
-
Kiwis
-
Penguins (they “fly” underwater!)
