The long-legged waders are comprised of the egrets, herons, ibises, spoonbills, storks, and flamingos. They are a diverse group, united by their long legs that enable them to wade for food. The egrets and herons are in the Ardeidae family, while the ibises and spoonsbill belong to Threskiornithidae. These two families belong to the same order and it is considered by some to be the same order as the storks (Ciconiiformes), but DNA information is prompting them to be moved to a different order. The flamingos belong to their own order, Phoenicopteriformes.
