This species was known from Lord Howe Island, Australia, but has not been definitely recorded since 1790 and was Extinct by the time the island was settled in 1834. Hunting was the major cause of its decline.
|Range Description:||Porphyrio albus is known from two skins in Liverpool and Vienna (Taylor and van Perlo 1998), several paintings, and some subfossil bones from Lord Howe Island, Australia (Marchant and Higgins 1993). Although not uncommon when discovered in 1790, the species was rapidly hunted to extinction; it had probably already vanished by the time the island was colonised in 1834 (Hindwood 1940).|
