Одноцветная сутора Cholornis unicolor

Dark brown parrotbill with a stout yellow bill and an arching black eyebrow. Like many other parrotbills, shows a strong affinity for bamboo thickets, in which it moves about noisily in small flocks. Very similar in appearance to Three-toed Parrotbill, but lacks that species’ pale wing panel and has less extensive black on the face. Gives a rolling liquid chirp.
