Orthonyx Novae Guineae

Arfak Mountains, New Guinea

.

Formerly considered conspecific with O. temminckii, but genetic studies indicate that it is closer to O. spaldingii#R#R. Differs from O. temminckii in its much narrower strip of white from chin to belly in male (2); altogether darker plumage in male on crown, head sides to flanks and back to tail (2); smaller size (but size varies with subspecies and samples variable and few; ns); and very different voice, with much lower-pitched notes (first harmonic) (4), and phrases of basically one note repeated (4)#R. Genetic analysis also suggests that nominate race may be a separate species from dorsalis and victorianus, but limited evidence indicates that voices are similar; last two races often merged. Racial identity of population recently found in EC New Guinea (Tari area, in Southern Highlands Province) unknown. Three subspecies recognized.

  • O. n. victorianus van Oort, 1909 – Herzog Mts and Wharton Range, in E New Guinea.
