The bird’s body is perfectly adapted for aerial life. Various aerial adaptations found in birds are:

  1. Body shape: The body of birds is streamlined. Necks stretched forward with the head pointed in front and a narrowed tail at the end provide them a sleek shape. The body surface is smooth to minimize resistance against air.
  2. Wings: The forelimbs are modified into wings.The fingers are very much reduced. The whole length of the forelimb carries long flight feathers.         .
  3. Steering and brakes: The feathers on the tail help to slow down the speed and also help in steering (changing direction).
  4. Wing muscles: These are the much strong, active and enlarged breast muscles.
  5. Cutting down the body weight: Except for the most necessary bulky heavy wing muscles, the rest of the bird’s body tends to be light to facilitate flight.
  • Bones have air cavities.
  • Much less water is required in the body. The birds excrete solid urine (formed of uric acid instead of urea which otherwise requires much water to be excreted out).
  • Right ovaiy and oviduct are greatly reduced.
