Adults of the nominate subspecies are mostly brownish throughout. They have dark streaks on the side of the head and on their hindneck. Their undersides are mottled or barred with rufous-brown. Their uppertail coverts are white and their tail is mottled grayish and white with a wide black band near the end. Also, their iris is brown. Males have bare yellow skin around the eye and yellow legs and feet. Females have reddish-pink skin around the eye and bluish-gray legs and feet. Juvenile birds have a strong rufous tinge overall and bare parts colored like the adult females.
