Phylogeny: 

Taxonomy: Amblyornis macgregoriae De Vis, 1890, Musgrave Range, c. 2130-2740 m, south-east New Guinea. Has hybridized with A. subalaris. Race germana, bowers of at least some of which differ from those typical of species, possibly represents a separate species. Seven subspecies recognized. Subspecies and Distribution: mayri E. J. O. Hartert, 1930 - W & C New Guinea (Weyland Mts E to W Hindenburg Mts). kombok Schodde & McKean, 1973 - E New Guinea probably from at least Strickland R (possibly from Hindenberg Range) E to Mt Hagen, Kubor Range, Bismarck Range and Kratke Range. lecroyae C. B. Frith & D. W. Frith, 1997 - Mt Bosavi, in EC New Guinea. amati T. K. Pratt, 1982 - Adelbert Mts, in NE New Guinea. germana Rothschild, 1910 - mountains of Huon Peninsula, in NE New Guinea. macgregoriae De Vis, 1890 - SE New Guinea from W Kukukuku and Herzog Range E to W Owen Stanley Range. nubicola Schodde & McKean, 1973 - E Owen Stanley Range (Mt Dayman and Mt Simpson massifs, and probably E from Mt Suckling), in extreme SE New Guinea.

Distribution: 

Endemic to mountains of eastern and central New Guinea; widespread on central cordillera, west to Weyland Mountains, Irian Jaya, and on the Adelbert Range, the Huon Peninsula, and Mount Bosavi. Occurs mostly at 1,600–2,300 m altitude. A. m. macgregoriae: W. Kukukuku and Herzog Range east to western Owen Stanley Range; A. m. mayri: Weyland Mountains, Irian Jaya, to eastern Star/western Hindenburg Mountains; Amblyornis m. lecroyae: Mount Bosavi; A. m. kombok: Kubor, Hagen, and Bismarck Ranges, probably west to at least Strickland River or Hindenberg Range and east to Kraetke Range; A. m. amati: Adelbert Mountains; A. m. germanus: Huon Peninsula; A. m. nubicola: Simpson-Dayman massifs, eastern Owen Stanley Range, probably west to Mount Suckling.

Habitat: 

Primary tall mixed montane and Nothofagus rainforest.

Migration: 

Sedentary

Trophic strategy: 

Primarily frugivorous, taking fruits from numerous trees, shrubs, and vines. Also eats flower parts and insects.

Reproduction: 

Polygynous, with promiscuous adult males and exclusively female nest attendance. Breeding season variable across the species range. Typically builds bulky open cup nest in pandanus tree crown 2–3 m above ground. Nest is composed of a sparse stick foundation, a leafy cup, and an eggcup lining of supple twiglets/rootlets. Lays a single, pale, unmarked, buff egg. One known incubation period was over 17 days. Nestling period unknown.

Risk statement: 

Not threatened
