Very elusive, chickenlike bird of humid evergreen forest in foothills and highlands; scarce and very local in eastern Mexico where it is endemic. Usually in pairs or small groups on the forest floor. May be seen beside quiet trails and roads early and late in the day; runs away quickly and rarely flies. Note the blue-gray face and throat, red bill and eyering, and rusty breast. Loud rollicking songs are given mainly early and late in the day and most often reveal its presence.
