Pachycephala olivacea

Small41 gShrubland

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.
