Habitat

Found across parts of South America, including Argentina, Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Trinidad and Tobago, and Venezuela. It primarily inhabits freshwater marshes with deep water and dense vegetation, as well as rice paddies, wet savannas, and swampy stream margins. The species typically occurs below 500 m in elevation but has been recorded as high as 2,600 m in the Colombian Andes.

Diet

The diet consists of grass seeds, various insects, and spiders. It forages both within cover and on open floating vegetation, seldom choosing to swim. Foraging behaviour includes climbing on grass stalks and bending them to access seeds.

Despite sharing habitats with the purple gallinule, the azure gallinule specifically prefers areas with shorter vegetation and no bushes. It is monogamous and both sexes participate in incubating a clutch of four or five eggs.
