Astoundingly odd ground-dwelling inhabitant of dense lowland and foothill forests; typically quite shy and reclusive, but utterly unmistakable. Warm brown with a burst of bright color on the face: black, white, yellow, orange, and rusty red. Of these, the white and black are most obvious if the bird is under heavy cover or in the shade (as it often is). Long, slender, wader-like legs, neck, and bill are unlike any other forest ground-dweller in range. Displaying birds inflate purple balloons on the neck and sing a haunting whistle that gradually rises and falls in pitch.
