Birdfinding.info ⇒  Locally common across much of its large range, mostly in areas with extensive floating vegetation.  In Florida, common year-round in interior wetlands from around Orlando south, especially in the Everglades at sites such as Green Cay Wetlands and Loxahatchee National Wildlife Refuge.  Also common in marshlands east of Houston, including Anahuac, Cameron Prairie, and Lacassine National Wildlife Refuges.

Purple Gallinule

Porphyrio martinica

Freshwater wetlands from southern North America to Argentina, usually associated with floating vegetation.

In North America, breeds on the coastal plain of the southeastern U.S. from South Carolina south through Florida and west to Texas, locally in bottomlands inland to southeastern Oklahoma and southern Arkansas.  Present year-round along the Gulf Coast and throughout Florida; elsewhere in summer only.

In Middle America, resident in Pacific lowlands north to Nayarit, locally in western interior valleys to Guanajuato, and throughout the Gulf and Caribbean lowlands.  Also throughout the West Indies on islands with freshwater marshes.

In South America, resident in Pacific lowlands south to Ecuador, and widespread throughout the continent’s northern, central and eastern lowlands south to the vicinity of Buenos Aires, Argentina.

Movements.  Partly migratory in the northern part of its range, moving north from March to May and south from August to October.

Prone to wandering, in both spring and fall, north across most of eastern North America—regularly to Bermuda, the Great Lakes, and the Maritimes, exceptionally to the interior of Quebec and Labrador.

In western North America, strays fairly regularly north and west across Mexico and into Arizona, more exceptionally to California, Nevada, Utah, Colorado, and Wyoming, with at least one having reached Hawaii (Maui in February 2018).

In South America, strays regularly from lowlands up into high Andean valleys, to the Pacific lowlands of Peru and northern Chile, to the Galápagos, and exceptionally south to southern Patagonia and the Falkland Islands.

Across the Atlantic, it is a fairly frequent vagrant to Macaronesia (records from Azores, Madeira, the Canary Islands, and Cape Verde) and western Europe, north to Iceland and Norway, and inland to Switzerland, with at least one having reached South Africa (Port Edward, KwaZulu-Natal in November 2004).

Identification

Adult is distinctive: a beautiful combination of deep violet and indigo from head to breast with shiny blue-green back and wings, and a tricolored “candy corn” bill.

The bill is mostly red with a yellow tip and blue-gray frontal shield.

The upperparts are most typically blue-green but vary from deep-blue to turquoise to bronzy or brownish.

The lower belly is black, contrasting with prominently bright-white fluffy undertail.

The legs and feet are bright yellow and disproportionately large, especially the toes.

Immature Plumages.  Juvenile is mostly buffy, beige, or yellowish on the head, neck, and underparts, pale brown on the upperparts, often with a blue-green cast on the wings.  Juvenile’s bill has a pale yellowish tip and darker base.  Easily mistaken for the smaller, rarer Azure Gallinule of South America (see below).

Older immatures develop adult plumage and bill coloration in variable progressions, with some retaining mostly brownish plumage while the bill changes color and others developing extensively blue and green feathers before the bill changes.

Voice.  Clucks, honks, cackles, and screams.

Cf. Azure Gallinule.  Across much of South America, immature Purple Gallinule can be mistaken for immature Azure Gallinule.  Immature Azure is typically much paler, with whitish underparts, but immature Purple is variable and some individuals also have whitish underparts.  Bill color is a more consistent difference: Azure’s bill is uniformly yellowish, whereas Purple’s bill is briefly dark brown in juveniles, then at an early stage begins to show the adult pattern: mostly red with a yellow tip.

Cf. Allen’s Gallinule.  The Allen’s Gallinule of Africa has very similar plumage to Purple’s, and differs primarily in having all-red legs and bill.  Both species have histories of long-distance vagrancy, with multiple records from western Europe and Macaronesia.

Notes

Monotypic species.
