Answer:
The bodies of birds are Streamline to reduce the air resistance during flying.
In easy words, to let them fly properly.
Explanation:
The bodies of all flying birds are shaped like teardrops. The streamlining is achieved by specially arranged feathers that reduce the friction that would otherwise act as a drag against the forward-moving body. The bodies of birds of all sizes share the same streamlined shape.
