Distribution and Reproduction by the Purple Gallinule (Porphyrio martinica) in Arkansas

Abstract

The Purple Gallinule ( Porphyrio martinica ) is a rare bird in Arkansas, and its populations likely have declined due to loss of marshy areas with emergent vegetation. By use of online sources for citizen science combined with a field study, we elucidate the current distribution of this bird in Arkansas, and document characteristics of reproduction and development. Purple Gallinules arrive in Arkansas as early as April and remain to late October. Nesting occurs from early May into July, and nests may represent second broods. Ontogenetic changes in in plumage and bill coloration hatchlings are described.
