Whistlers (Pachycephalidae)

Olive Whistler (Pachycephala olivacea) - HBW 12, p. 412

French: Siffleur olivâtre German: Buchendickkopf Spanish: Silbador Oliváceo
Other common names: Olivaceous Whistler, Olive Thickhead, Native Thrush, Whipbird

Taxonomy: Pachycephala olivacea Vigors and Horsfield, 1827, no locality = probably hinterland of Parramatta and Blue Mountains, east New South Wales, Australia.
Probably closest to P. rufogularis and P. inornata, and all three sometimes combined in subgenus Timixos; has been suggested that these three species represent one of the earlier lineages in the genus. Traditionally only two races, nominate and macphersoniana, recognized; more recent proposal to separate others is based on slight differences in size, plumage and sexual dimorphism that occur as stepped breaks coincident with geographical barriers. Five subspecies currently recognized.

Subspecies and Distribution:

  • macphersoniana H. L. White, 1920 - E Australia from extreme SE Queensland (Macpherson Range) S in mountains to E New South Wales (Barrington Tops).
  • olivacea Vigors & Horsfield, 1827 - mountains of SE New South Wales and C & NE Victoria.
  • bathychroa Schodde & Mason, 1999 - S Victoria (Otway and Strzelecki Ranges).
