Birds have passed through many structural diversifications to match their aerial life. Some of those variations are as follows. (i) Streamlined frame for speedy and clean movement (ii) Covering of feathers for insulation(iii) Forelimbs changed into wings and hind limbs used for walking, perching, and swimming (iv) Presence of pneumatic bones to lessen weight (v) Presence of extra air sacs to complement respiration
