The American Purple Gallinule (Porphyrio martinica) is a “swamp hen” in the rail family Rallidae. A medium-sized rail (33 centimetres (13 in) in length) with big yellow feet, purple-blue plumage with a green back, and red and yellow bill. It has a pale blue forehead shield and white undertail.
Juveniles are brown overall with a brownish olive back. These gallinules will fly short distances with dangling legs. Their breeding habitat is warm swamps and marshes in southeastern states of the United States and the tropical regions of Central America, the Caribbean and northern South America. This species is resident in southern Florida and the tropics, but most American birds are migratory, wintering south to Argentina.
