Tongan whistler
The Tongan whistler is a species of bird in the family Pachycephalidae. It is endemic to the islands of Vava'u and Late in Tonga. It is mainly found in tropical primary forest, but can sometimes be seen in second growth or wooded plantations. It is similar to the Australian golden whistler in appearance, but the head and throat of the male is entirely black, and the underparts of the female are yellow. The Tongan whistler is threatened by habitat loss. The Tongan whistler was also described by Jacques Pucheran in the genus Eopsaltria and has been variably considered as a subspecies of the golden whistler.
