An Ostrich’s eye is bigger than its brain.
Not only is the ostrich’s eye bigger than its brain, but they also possess the largest eyes of any bird. Their eyes are about 2 inches in diameter, the size of a pool ball. This makes them five times larger than human eyes.
Those huge eyes aren’t just for show either—ostriches have fantastic vision. The birds can see for long distances, thanks to their height and sharp eyes, allowing them to spot predators before they get too close.
