Adults of the nominate subspecies P. r. ruficeps have a bright rufous crown and a gray nape that are separated by a black line that continues onto the cheek. They have a white to buffy area above the lores, a thin black line through the eye, and white to buffy cheeks. Their back, rump, and uppertail coverts are olive. Their wings are black with yellowish white edges on the flight feathers and yellow tips on the coverts; the latter show as two thin wing bars. Their tail is olive-brown. Their throat and upper breast are buffy whitish with a faint dusky or blackish band under the breast. The rest of their underparts are bright yellow. Juveniles have paler throats than adults. Subspecies P. r. rufigenis has a very faint or no black line on the cheek. P. r. peruvianus has bolder black markings on the face and a whiter throat than the nominate. P. r. melanomystax has whitish cheeks; the black line on the nape widens onto the sides of the neck. All subspecies have a dark brown iris, a black bill, and gray legs and feet.
