Large finchlike bird with a strong bill with obviously curved mandibles. Males have a distinctive face pattern—a gray head with a broken pale eyebrow, and a prominent pale mustache and throat. Olive-brown above and gray below with two pale wingbars. Females have no facial marks and are olive-brown overall with two indistinct cinnamon wingbars. Found at the forest edge and in second growth where it is largely dependent on bamboo patches.
