About These Birds
Marquesan Swamphen
Marquesan Swamphen (Porphyrio paepae) is an extinct flightless swamphen known only from subfossil bones from the Marquesas Islands, French Polynesia. Lost following Polynesian settlement and later European contact. Part of the broader pattern of Pacific island rail extinctions linked to human arrival and introduced rats.
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.
