The nominate subspecies has a very dark chestnut crown and plain brown upperparts, lighter on the rump. Most of the face is gray with a ring of bare red skin around the dark brown eye. The tail is dark brown and almost black near the tip. The chin, throat, breast, and flanks are rufous and the belly is buffy. The bill is mostly blue-gray and the feet dull brown or greenish gray.
