Bougainville Thicketbird Cincloramphus llaneae Scientific name definitions

17–19 cm. A relatively long-tailed, medium-sized warbler. Distinctive compared to other members of complex (M. whitneyi, M. grosvenori, M. turipavae), dark olive-brown (almost sooty) above, with distinct but comparatively small black mask, blackish lesser wing-coverts with pale brownish-olive feather edges (appearing heavily scalloped), blackish tail (not frayed or spine-tipped, but this could be due to specimens having new, unworn feathers), supercilium and chin to upper breast rich reddish cinnamon, shading to drab or dull brown on belly and below this, also outermost primary more or less equal to next three (blunt wingpoint); bill dark, and legs and feet dark brown.

Bougainville I (Crown Prince Range, in C of island, possibly also Mt Balbi, in N).

Not globally threatened. Currently considered Near Threatened. Restricted-range species: present in Solomon Group EBA. Because of its extremely shy and retiring habits and also the nature of its habitat (wet montane forest), status difficult to assess with accuracy, but the species is believed to be decreasing. Despite very few field observations, believed to be possibly relatively numerous; known only from type locality in Crown Prince Range, in C Bougainville, but song believed to be of this taxon has been heard elsewhere, notably on Mt Balbi (in N of island). Known from just 47 km², and total population is therefore assumed to be between 1000 and 7000 birds. Nevertheless, montane forest remains remarkably intact. Introduced mammalian predators, notably feral cats, are the most likely threats for these terrestrial birds.
