Question

Which bird has biggest eyes than its brain?

Answer 1

Chickens . If you take away their beaks, feathers, fleshy crests, skulls and eyes from their heads, then the typical hen or rooster will have less airspace left for its brain than the space taken up by its eyes.

Answer 2

Ostriches and owls both have eyes larger than their brains. Owls' eyes are so huge that there is no room inside the skull for muscles to move them - owls are unable to move their eyes, and must turn their heads to change where they're looking.

Answer 3

an ostrich, i guess
