The olive whistler (Pachycephala olivacea) or olivaceous whistler, is a species of bird in the family Pachycephalidae, the whistlers, that is native to southeastern Australia. Adult birds are around 18–20 cm (7–8 in) long, and have an overall olive brown plumage with a streaked white throat. To an untrained eye, they can be mistaken for female golden whistlers. The male has a dark grey head, pale grey breast and red-tinged buff belly and rump. The female lacks the red tinge, and has brown underparts. The legs, bill and eyes of both sexes are a brown-black. The melodious call has been likened to I'll wet you or you're cranky, and is possibly the most musical of all whistlers.
