The smallest bird egg belongs to the Hummingbird and is the size of a pea.

A bird's eye takes up about 50 percent of its head; our eyes take up about 5 percent of our head.  To be comparable to a bird's eyes, our eyes would have to be the size of baseballs.

The penguin is the only bird that can swim, but not fly.  It is also the only bird that walks upright.

Owls can turn their heads 270 degrees (a complete circle is 360 degrees).  They cannot move their eyes as they are fixed in the socket.

The first bird domesticated by humans was the goose.

Kiwi birds are blind, so they hunt by smell.

When it comes to birds, the males tend to have the more glamorous feather shape, coloration, songs, and dances.  Female birds choose their mate based on how attractive they find them.

Crows have the largest cerebral hemispheres (brains), relative to their body size, of any avian family.

The common phrase "eat like a bird" should mean something quite different.  Many birds eat twice their body weight in food each day.  In fact, a bird requires more food in proportion to its size than a baby or a cat.

It is estimated that one third of all bird owners turn on a radio for their pet when they leave the house.
