Question

Birds fly with the help of:

• A. Patagium
• B. Wing
• C. Feather
• D. Limbs

Answer 1

The correct option is B Wing

• Forelimbs of birds are modified into wings which help birds in flight.
• The body of birds is covered with feathers. Feathers do not directly help in flight. However, they hold air and help in making body buoyant.
• Patagium is a fold of skin which helps some animals in gliding. It is a mammalian structure and not present in birds.
• Limbs also do not help birds to fly but limbs modified into wings that help to fly.
• Thus, the correct answer is option B.
