About These Birds
Calayan Rail
Calayan Rail (Aptenorallus calayanensis), 20 cm. Brown above; grey underparts; yellow-green bill; short wings suggesting flightlessness. Discovered in 2004; endemic to Calayan Island, Philippines. Inhabits forest undergrowth. Omnivore. Endangered; tiny single-island range with minimal forest remaining.
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.
