About These Birds
Dusky Moorhen
Dusky Moorhen (Gallinula tenebrosa) is a 35–40 cm moorhen of Australia, New Guinea, and Indonesia's freshwater wetlands. Dark slaty-grey with brown back, red frontal shield, and yellow-tipped red bill. Common on lakes, rivers, and park ponds. Walks along shorelines and swims freely. Feeds on aquatic plants, invertebrates, and seeds.
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.
