Australasian Treecreepers (Climacteridae)

Papuan Treecreeper (Cormobates placens) - HBW 12, p. 657

French: Échelet papou German: Papuabaumrutscher Spanish: Corretroncos Papú
Other common names: New Guinea Treecreeper

Taxonomy: Climacteris placens P. L. Sclater, 1874, Hatam, Arfak Mountains, New Guinea.
Genus previously merged into Climacteris, but differs in structure (bill shape, leg length, sole pads, skull, secondaries), egg coloration, plumage (juvenile characteristics, sexual dimorphism) and behaviour; generic separation corroborated by molecular evidence. Genus name originally combined with feminine adjectives, so deemed to be feminine. Forms a superspecies with C. leucophaea, and has in the past been treated as conspecific. There has been no recent taxonomic revision of this species, and distributional limits are uncertain. Four subspecies traditionally recognized.

Subspecies and Distribution:

  • placens (P. L. Sclater, 1874) - Vogelkop (Tamrau Mts, Arfak Mts), in NW New Guinea.
