Field Identification

33 cm. Probably flightless. Sexes alike; female possibly slightly larger. Very similar to H. woodfordi, but differs in having brown upperparts, medium dark slate grey underparts with faint pale barring from flanks to undertail-coverts, somewhat more marked facial pattern, tawny bars on remiges, white bars on all underwing-coverts, brown eye, yellow or orange-yellow bill and yellow legs. Immature and juvenile undescribed.

Systematics History

Previously placed in genus Nesoclopeus; has at times been placed in Rallina or even Rallus. Closely related to H. woodfordi, and has been considered conspecific. Monotypic.

Subspecies

There have been no convincing recent reports from Ovalau or Taveuni, which remain free of mongooses (Herpestidae) and where other rail species were recorded during surveys and other fieldwork in 2002–2005 (1). Elsewhere, predation by introduced cats and mongooses is thought to have been responsible for its decline and ultimate extinction.

Distribution

Fiji: twelve 19th-century specimens from Viti Levu and Ovalau; unconfirmed reports from Taveuni in 1971 (2) and from Viti Levu (Waisa, near Vunidawa) in 1973 (3).

Habitat

Remote forested areas, secondary forest, old taro fields and possibly swamps.

Movement

None.

Diet and Foraging

No information available.

Sounds and Vocal Behavior

Not described.

Breeding

Recorded nesting Oct–Dec and possibly Mar. One nest, “of sedges”, contained 6 eggs; on another occasion a male and 4 eggs were obtained by local people. No other information.

EXTINCT. An unconfirmed record from N of Waisa, near Vunidawa, Viti Levu, in 1973, the first record since 1890; however, species is thought unlikely to have survived there because a number of other ground-dwelling species, including two non-endemic volant rails (Gallirallus philippensis and Porphyrio porphyrio), have disappeared as a result of predation by introduced mongooses and feral cats. Extinct on Taveuni, where it was probably rare even before the introduction of mongooses and was regularly hunted by dogs. Known from 12 specimens collected on Viti Levu and Ovalau in 19th century; no estimate ever made of its abundance because it was shy and seldom seen.
