About These Birds

White Swamphen

White Swamphen (Porphyrio albus) is an extinct all-white swamphen formerly endemic to Lord Howe Island, Australia. Known from specimens collected around 1790 and early drawings; had reduced wings indicating flightlessness or near-flightlessness. Extirpated by hunting after European discovery. Related to Australasian Swamphen.

Allen's Gallinule

Allen's Gallinule (Porphyrio alleni) is a small 23–26 cm, colorful gallinule of sub-Saharan Africa. Deep blue-purple plumage with olive-green back, red bill and frontal shield, and red legs. Inhabits dense freshwater marshes, floating vegetation, and papyrus swamps. Partially migratory; disperses widely after rains.
