The penguin is a bird, but it does not fly. Penguins are not like other birds. They are unique birds, and although they do have feather, even their feathers are unusual. Other birds have rows of feathers that grow in a specific pattern. A penguin,s feathers grow all over, like hair on a mammal. You will not see penguins in the air, and you will not see them in trees. You will see them in the water, in fact you will see them below the surface of the water if you have an underwater video camera.
