, 1883,

Fergusson Island

.

Affinities uncertain. Hitherto considered one of four distinctive subspecies grouped under the name O. nobilis, but here treated as full species (see under O. nobilis). The form insularis (Fergusson I) differs from all other taxa in Otidiphaps in possessing no backward-directed crest (2); no coloured nuchal patch (simply blackish) (3); wings markedly paler rufous than in other taxa (ns[1]); rump dull green (strong green in cervicalis, dark blue in others), uppertail-coverts and tail dark blue (strong green in cervicalis, dark blue in others) (ns[1]); underparts dull matt black, with virtual absence except slightly on breast of the glossy blue or green that is extensive on other taxa (2). Monotypic.

Distribution:

Fergusson I (D’Entrecasteaux Is), off SE New Guinea.

Movements

Resident and sedentary.

Status and conservation

ENDANGERED. Population estimated to number 600–1700 individuals based on an assessment of known records, as well as descriptions of abundance and range size (just 1300 km²).... read more
