Taxonomy
Subspecies
There are 4 subspecies [1] which some authorities (e.g. [3]) treat as separate species:
- O. n. nobilis: "Green-naped Pheasant-pigeon". Mountains of western New Guinea, Batanta and Waigeo islands
- O. n. aruensis: "White-naped Pheasant-pigeon" has white hindneck, much less coppery nuchal area of mantle, greenish blue breast, slightly paler, less purple mantle and shorter crest. Aru Islands New Guinea
- O. n. cervicalis: "Grey-naped Pheasant-pigeon" has greyish-white hindneck, brown nuchal area of mantle, greenish blue rump and blackish-green underparts. Mountains. of east and southeast New Guinea (Saruwaged, Sepik and Kuper)
- O. n. insularis: "Black-naped Pheasant-pigeon" has no crest, no coloured nuchal patch, wings markedly paler reddish brown than in other subspecies, rump dull purplish, tail base dull greenish, tail and uppertail-coverts dark blue, underparts matt black, with very little iridescence except slight amount of blue or green on breast. Known from 2 specimens collected in 1882, this taxon was filmed for the first time in 2022 [4]. Fergusson Island. (D'Entrecasteaux Archipelago)
Habitat
Mainly in hills up to 1900 m and in lowlands Usually occurs in primary rainforest but sometimes monsoon forest at lower altitudes.
Behaviour
Normally solitary, sometimes in pairs, acts like a pheasant. Resident and sedentary.
Diet
Eats seeds and fallen fruit, sometimes visits display grounds of Wilson's Bird-of-Paradise to search for regurgitated seeds and shows aggressive behaviour towards it. Injests pebbles up to 1 cm in diameter to help digestion. Forages by slow movement along the ground and is known to drink from streams.
Breeding
It is thought to nest on the ground and lay only a single egg.
Vocalisation
Advertising call is a far carrying loud “wu-huwoooaaa” that modulates in pitch with a trailing end. Call lasts 1.4–2 seconds and repeated about 8–10 seconds or more. Male display calls are a “woooou” rising in the middle, and a screeching “crrouwwwwwww”, starting very loudly and lasts about 5 seconds. Calls from perch in the undercanopy and ground.
