Taxonomy: Pachycephala schlegelii lorentzi Mayr, 1931, Hellwig Mountains, Oranje Range, New Guinea. Originally considered conspecific with P. schlegelii, but subsequently discovered to occur sympatrically with that species. Both are members of a species group that includes also P. orpheus, P. nudigula, P. meyeri, P. soror, P. implicata, P. pectoralis, P. caledonica, P. jacquinoti, P. flavifrons, P. melanura and P. aurea. Monotypic. (source: Handbook of the Birds of World)
Distribution:
- Highlands of C New Guinea from E Snow Mts E to Hindenburg Mts and Victor Emanuel Range.
Mid- montane forest, mossy forest of southern beech (Nothofagus), and alpine shrub growth, at 1750- 3800 m. Where range overlaps with that of P. schlegelii, it replaces that species above 2700 m, but the two co- exist lower in altitudinal range.
Insects. Gleans prey mainly in lower to middle storeys of forest; forages also at tops of saplings in clearings. No reported differences from P. schlegelii.
