Scientific name: Porphyrio albus
Common name: White Gallinule
The White Gallinule is a conventionally accepted species (Christidis & Boles 1994; Marchant & Higgins 1993). The taxonomic relationship of the White Gallinule with other species of gallinules has been debated since its discovery. It was first considered to be most closely related to the coots (Fulica spp.), but was later considered to have a closer relationship with the Takahe of New Zealand (Porphyrio hochstetteri). It is now thought to be most closely related to the Purple Swamphen (Porphyrio porphyrio), with which it is sometimes considered conspecific (the same species, different subspecies) (Christidis & Boles 1994; Marchant & Higgins 1993).
The White Gallinule was a large flightless rail with white plumage and a massive red bill. It was 55 cm in length (Hutton 1991). Most birds had entirely white plumage, although some were seen with blue-and-white plumage, and others with blue plumage (Hindwood 1940).
The White Gallinule formerly occurred only on Lord Howe Island in the south-west Pacific Ocean (McAllan et al. 2004; Marchant & Higgins 1993). Its date of extinction is unknown, but it was last recorded in May 1788 when it was considered common (Hindwood 1940; McAllan et al. 2004), and possibly before the first settlement in 1834 (Hindwood 1940; McAllan et al. 2004).
The White Gallinule was formerly described as occurring in 'great numbers' and 'great plenty', though it has been suggested that these descriptions exaggerated its abundance (Hindwood 1940).
There have been a number of ornithological surveys on Lord Howe Island in the 20th century (Disney & Smithers 1972; Recher 1974; Recher & Clark 1974), but there has been no sign of the species.
Little is known about the ecology of the White Gallinule. It is thought to have inhabited the lowland woodlands of Lord Howe Island (Garnett & Crowley 2000; Marchant & Higgins 1993).
The White Gallinule is claimed to have interbred with the closely related Purple Swamphen (Porphyrio porphyrio), vagrants of which occasionally visited Lord Howe Island. However, some authors believe this claim to be doubtful (Hindwood 1940).
The Purple Swamphen (Porphyrio porphyrio) is capable of breeding when one year old, but this usually only occurs in small populations. Within larger groups, birds seldom breed when less than three years old (Craig 1980). The Purple Swamphen builds a platform of grass or reeds with a shallow depression into which two to six pale brown eggs with spots and blotches are laid (Brown & Brown 1977; North 1901-1914; Stidolph 1939).
Nothing is known about what the White Gallinule ate, but it probably foraged on the ground (Hutton 1991), which may have made it more vulnerable to predation. The closely related Purple Swamphen (Porphyrio porphyrio) eats mainly aquatic vegetation, though also occasionally eats insects, small vertebrates and eggs (Carroll 1966; Marchant & Higgins 1993; Norman & Mumford 1985). The related Takahe (Porphyrio mantelli) eats mainly shoots of grass and ferns (Marchant & Higgins 1993; Mills & Mark 1977; Mills et al. 1980).
There are no recorded movements of the White Gallinule. However, given that it was flightless, it was probably sedentary. The closely related Purple Swamphen occurs in pairs and small groups, and the Takahe occurs solitarily, in pairs and small groups (Marchant & Higgins 1993).
Being a large gallinule with white plumage and a large red bill, the White Gallinule would have been distinctive. When first recorded by the early explorers, it appears to have been easy to detect. One early visitor to Lord Howe Island caught six individuals (Hindwood 1940).
Though the White Gallinule has been extinct since the first half of the 19th century, if a survey were to be conducted, it should consist of area searches within a radius of 500 m at various sites, or possibly transect surveys. Either method, with the objectives of sightings or detection by call, footprints, feathers or nests, would be useful in establishing whether the species was present at a site (Magrath et al. 2004).
The extinction of the White Gallinule is thought to have resulted from hunting by sailors, whalers and other visitors to Lord Howe Island. The bird was regularly killed for food, and was said to be good eating (Hindwood 1940; Hutton 1991).
