A fairly small, plump bird with a unique bill shape of montane forest. Male is yellow-green with black wing, chest, and two large, pink, fleshy wattles beside the bill. The female is olive-green with paler underparts. Forages low and especially likes climbing bamboo. Uses its strong bill to strip wood and dig into branches. Male plumage is unique, but even with the female’s non-descript plumage, the bill shape should be a give-away. Voice, a single, long, high-pitch note.
