Новогвинейская клинохвостка Cincloramphus macrurus

A medium-sized bird of grasslands. Long, pointed tail, upperparts with bold, black streaks, pale gray underparts and a whitish throat. Crown, wing and tail washed rufous. Likes to stay hidden but when flushed, flies low, from one clump of vegetation to the next. Separated geographically from Fly River and Tawny Grassbirds. Little Grassbird is smaller and lacks rufous in the wing. Australian Reed-Warbler, superficially similar but lacks streaking. More often heard than seen. Voice, an explosive “chwik!” often given while sat on top of vegetation.
