Black-faced Warbler

The Black-faced Warbler is a tiny, delicate warbler with olive-green upperparts, yellow underparts, a black crown stripe, and a bold black face pattern. It inhabits montane forests and bamboo thickets from the eastern Himalayas through southern China to northern Vietnam, typically at elevations between 1,500 and 3,000 meters. It is highly active, constantly flitting through dense foliage gleaning tiny insects and spiders.
