Question

A bird with movable upper jaw is

• A. Vulture
• B. Parrot
• C. Sparrow
• D. Pigeon

Answer 1

The correct option is B Parrot

A) Animals which must exert powerful bite forces, such as crocodiles and vultures, often have rigid skulls with immovable maxillae (upper jaw) for maximum strength.

B) Animals which swallow large prey whole, like snakes and animals which grip awkwardly shaped food items (parrots eating nuts), have movable upper jaws.

C) Sparrows do not have a movable upper jaw as they eat small seeds and do not need a movable upper jaw.

D) Pigeons do not have movable upper jaws.

So the correct answer is 'Parrot'.
