Birds are vertebrates of the class Aves. Most birds are able to fly, but some, like ostriches and penguins, cannot even though they still have wings. All birds hatch from eggs and are covered with feathers, the one major characteristic that distinguishes them from all other animals. Their feathers are made of keratin, which is similar to what our fingernails are made of, making the feather lightweight but strong. Feathers, along with wings, hollow bones, and a highly efficient respiratory system, help birds to fly. Potter Park Zoo has dozens of feathered friends, including the Ostrich, the world’s largest bird species!
