About These Birds
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.
Kosrae Crake
Kosrae Crake (Zapornia monasa) is an extinct flightless rail formerly endemic to Kosrae in the Caroline Islands, Micronesia. Known from bones and a single 19th-century description. Dark plumage, reduced wings. Extirpated following Polynesian and later European settlement; likely lost to introduced rats and cats.
