Plump, chickenlike bird found in cloud forest along the east slope of the Andes from extreme southern Colombia to Bolivia. It has chestnut underparts, brown upperparts that are boldly streaked with white, and black face and throat. Small coveys of birds walk on the ground inside forest, where they are shy and usually very hard to see well, though they do visit feeders in some areas. Far-carrying song is a long, rollicking series of whistles.
