Adult males are characterized by dark brown upperparts, a black head, and dull greyish-brown underparts, along with a red eye-ring and iris, and a long, black bill with a drooping tip. Females differ with dark cinnamon upperparts, a dark grey-brown head, and a rufous buff, finely barred breast and belly, transitioning to cinnamon on the lower breast; their iris is dark brown with a narrow whitish outer ring. Juveniles exhibit cinnamon upperparts, a pale grey and brown face, a dark eye-ring, and a dark brown iris. ^[2]
