Taiwan Bush Warbler Locustella alishanensis

Drab brown and skulking, this medium-sized endemic songbird can be difficult to locate but can be confiding once found. Largely rich brown and unmarked, but some birds have a streaked or spotted pattern on the pale throat. Brown-flanked and Yellow-bellied Bush Warblers are smaller and warmer brown, with a sharply contrasting supercilium. Breeds in mid- to high-elevation forests and edges and descends to lower elevations in the winter; stays low in dense bushes and shrubbery. Gives a hiccuping song consisting of melancholy whistles interrupted by ticking clicks. Calls are harsh rasping insect-like notes.
