Selayar Whistler

The Selayar whistler is a species of songbird in the family Pachycephalidae. Described by the Swiss zoologist Johann Büttikofer in 1878, it is endemic to the Indonesian island of Selayar, off the southwestern coast of Sulawesi. After its initial description, it was long considered a subspecies of the golden whistler and later the rusty-breasted whistler, before being raised to species status again in 2016. Selayar whistlers are around 16–17 cm (6.3–6.7 in) in length. Adult males have grey heads, white throats, olive-green upperparts, pinkish underparts, and brownish-olive tail and wing feathers. Adult females are largely similar to males, but have dark ochre lores and rufous ear-coverts. The similar appearances of the sexes in this species helps differentiate it from the rusty-breasted whistler; in that species, males have black-and-yellow plumage, contrasting with the female's olive-brown colouration.
