Meet the Real Big Bird

The ostrich is the world’s largest bird. Its eyes, alone, are the largest of any land animal, each measuring almost two inches across. However, even though its body, legs and eyes are huge, its brain is actually one of the smallest in proportion to its size. In fact, just one of its eyes is bigger than its brain.

Bonus fact: Ostriches can’t fly, but they can run up to 43 miles per hour.
