16–17 cm; 34–36 g. Male nominate race has crown feathers black with broad shiny blue tips (crown appears blue with black central patch and border), centre of nape with small ochre patch; lores whitish, side of head ochre, short white supraorbital line, white or buffy postorbital line, ear-coverts mottled dusky and buffy ochre; upperparts , including upperwing and tail, dark olive-brown, upper­wing-coverts with small buffy spot at tips; ochre below, throat paler, lower belly and flanks washed olive; iris dark brown; bill brown; legs greyish-olive.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Birds in C & E parts of range often separated as race brunnea, supposedly slightly richer in plumage coloration; but variation in colour tones is considerable, with no geographical pattern, and any true variation seems clinal (1). Monotypic.

Distribution

Mountains of w-central New Guinea

SUBSPECIES

Ifrita kowaldi kowaldi Scientific name definitions

Distribution

New Guinea (Central Highlands and mountains of Huon Pen.)

Distribution

Highlands of New Guinea from Weyland Mts and Nassau Range E, including Huon Peninsula, to Owen Stanley Range.

Habitat

Montane forest, particularly mossy forest ; c. 1460–3680 m, mainly 2000–2900 m.

Movement

Probably sedentary.

Diet and Foraging

Insects, including beetles (Coleoptera); occasionally soft fruit. Forages from low down, on fallen logs, to upper branches. Creeps up trunks and on branches in manner of a nuthatch (Sitta); probes into moss and on underside of branch while hanging on to upper surface, using tail as brace. Joins mixed-species foraging flocks.

Sounds and Vocal Behavior

Song 5 or 6 rapid, rather buzzing notes, slightly rising and then falling, “zig-zig-zig-zig-zig-zig”; also, a series of louder, squeaky, musical rising and falling notes with quality of a baby’s squeeze toy . Three-note “jitji-jit” when foraging; also a buzzy scold.

Breeding

Nest with egg in Sept, nests with chick in Oct and late Nov, and fledgling in late Aug, indicating breeding during middle and late dry season, start of wet season and late wet season, at least. Nest a deep, bulky, thick-walled bowl of green moss and some leaf-fern, lined with fine tendrils or rootlets, placed c. 3·6 m above ground in sapling. Clutch 1 egg, white with very sparse clear black and purple-black spots and blotches, larger and more dense at larger end, average 25·8 × 20·7 mm. No further information.

Not globally threatened. Generally fairly common, although occurs at low density in many places.
