Birds at Peoria Zoo
This class of animals contains species of every conceivable size, form and color. There are more than 9,000 species of birds alive today. Despite their amazing variety and diversity, all birds have one unique characteristic: feathers. Feathers do a number of things. They protect a bird's skin from wet, cold and injury; their colors and shape play a large role in attracting a mate; and of course, feathers allow a bird to fly.
