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.
Black-tailed Native-hen
Black-tailed Native-hen (Tribonyx ventralis) is a 30–38 cm flightless rail of inland Australia. Olive-brown with white flank spots, red eye, and upright black tail. Nomadic, following rainfall; forms large flocks at temporary wetlands. Grazes on grass and aquatic plants. Occasionally erupts in huge numbers after flooding. Not threatened.
