This species was found in Fiji, but it has not been recorded since 1973 and is now Extinct. Predation by introduced cats and mongooses is thought to have been responsible for its decline.

Geographic Range [top]

Range Description:Hypotaenidia poeciloptera is known from Fiji, with twelve 19th century specimens from Vitu Levu and Ovalau (Taylor 1998), and reports from Taveuni (Blackburn 1971) in 1971 and Waisa, Vitu Levu, in 1973 (Holyoak 1979). There have been no convincing recent reports from Ovalau or Taveuni which remain mongoose-free and where other rail species were recorded during field surveys and other fieldwork in 2002-2005, and so it seems very likely that H. poeciloptera is extinct (G. Dutson in litt. 2005).

Habitat and Ecology:It formerly inhabited the forests of the interior.

Continuing decline in area, extent and/or quality of habitat:Unknown
Generation Length (years):3.7
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Two other (non-endemic) rails have become extinct from the islands due to predation by introduced mongooses and cats, and so it seems very likely that this also caused the extinction of H. poeciloptera (Collar et al. 1994).
