Yellow-breasted Satinbird Loboparadisea sericea Scientific name definitions

17 cm; male 50–75 g, female 60–77 g. Basal upper ridge of culmen broadly flattened, gape wide, tail slightly graduated. Male nominate race has bulbous narial wattles (bilaterally bifurcate) and bare skin over mandible bases pale, chalky turquoise-green or yellow; lores and side of face dark brown, crown similar but with coppery-green sheen; nape, mantle and upper back honey-brown with darker feather tips, washed iridescent coppery yellow, lower back and rump pale silky iridescent sulphur-yellow; tail and upperwing and its coverts honey-brown, darker tips on primaries, secondaries and rectrices; malar area and entire underparts silky or glassy sulphur-yellow; thigh feathers dark brown; iris dark brown; bill blackish, mouth dull-coloured (lacking bright pigment); legs blackish. Female is slightly larger than male (uniquely within family), lacks wattles, and has different plumage, dark olive-brown above with cinnamon-brown on exposed wings, and paler, more yellowish-buff, underparts with darker streaking, especially on breast. Juvenile undescribed, possibly briefly grey; first-year immature dark olive-brown above, washed amber on wing and tail, lacking yellow, underparts cinnamon, dark feather edgings on breast forming broad greyish streaking, belly pale greyish; second-year plumage of both sexes like adult female, but darker below and less yellow above; tail of immature male longer than adult's, progressively shorter with age, wattles require at least a year to develop fully, changing from black, to black mottled with turquoise-green, to adult male colour. Race aurora male is fractionally larger than nominate, more so in tail length, and upperparts significantly brighter (paler), more brown-yellow, crown far paler and more greenish, less brown, narial wattle pale blue.

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Interior of middle montane forest; 600–2000 m, mainly above 1200 m.

No information.

Little known. Possibly almost exclusively fruits, simple drupes and berries plucked and swallowed whole; one individual had arthropods in stomach. Forages in canopy, lower canopy and upper middle storey, but also frequents lower strata of forest. Singly or in groups of up to ten individuals in fruiting trees or undergrowth.

Unconfirmed if male has advertisement vocalization. Calls include series of loud, harsh, grating notes slightly upslurred, "sssh sssh sssh", usually 2 notes followed by brief pause and again 2–3 notes, notes becoming slower and stronger as series continues; lower-pitched than notes of Lophorina superba.

Males with moderately enlarged gonads in Jun and Aug and greatly enlarged ones May and Oct. Presumed polygynous, with solitary promiscuous males; females build and attend nest alone. Nest said to be an open moss structure built in branches in vegetation; clutch reported as 1 egg by local informant. No other information.

Not globally threatened. Currently considered Near-threatened. Restricted range species: present in Central Papuan Mountains EBA. CITES II. Poorly known. Locally common, but patchily distributed; absent from seemingly suitable forests, perhaps owing to lack of significant food plants. Possibly overlooked because of its secretive behaviour and rugged, rarely visited habitat. Population appears to be fairly small, and declining owing to mining and logging activities. Habitat in most of its range, however, is reasonably secure, and probably safe from large-scale habitat degradation.
