Question

कौन-सा ऐसा जीव है, जो पक्षी नहीं है फिर भी उड़ता है?

1. A. कठफोड़वा
2. B. उल्लू
3. C. शुतुर्मुर्ग
4. D. चमगादड़ (Correct answer)

Correct Answer

Option D — चमगादड़

Detailed Solution & Explanation

The correct answer is चमगादड़ (bat).

Key Points

• The bat is the only mammal capable of true, sustained flight, yet it is not a bird.
• It is a mammal because it is warm-blooded, gives birth to live young, feeds them milk and has hair, not feathers. Its wings are membranes of skin stretched over elongated finger bones.

Additional Information

• Bats navigate by echolocation, emitting ultrasonic sound and interpreting the echoes.
• Woodpecker, owl and ostrich are all birds — the ostrich is a bird that cannot fly, the reverse of the case asked here.
