Southeastern USA to northern Argentina; also found in the West Indies.

Taxonomy

The South Georgia Gallinule, once described as an independent species Porphyrula georgica, was later shown to just be an aberrant Purple Gallinule, and as such is an invalid taxon, now considered synonymous with Porphyrio martinica³.

Habitat

Lives in freshwater swamps, marshes, and ponds.
