The Black-browed Reed-warbler is a small, streaky marsh bird that breeds in East Asia from Siberia and China to Korea and Japan, spending winters in South and Southeast Asia. It has a distinctive bold black supercilium, giving it a masked appearance, and buffy underparts. It inhabits dense reed beds, tall grass, and rank vegetation near water, feeding on small insects.
