Adult males have a golden yellow forehead and a red crown and nape. Adult females have a white to buffy white forehead, a black central crown, and a red hindcrown and nape. Both sexes have black around the eye that extends down the side of the neck and a white line behind the eye. Their upper back has black and white bars and their lower back and uppertail coverts are white with a pale buff tinge and sometimes some blackish bars. Their flight feathers are black or brownish black with narrow white tips and white bars throughout. Their tail is black with some white bars on the central pair of feathers. Their lores, cheeks, chin, and upper throat are whitish. Their lower throat and breast are olive-buff with a gray tinge and the rest of their underparts are buffish white with strong wavy bars and a red spot in the center of the belly; their undertail coverts are yellow-brown. Their bill is longish and black with a paler base to its mandible, their iris is brown, the bare skin around the eye brown to grayish, and the legs greenish gray to olive. Juveniles are duller and browner than adults, with more diffuse barring and a smaller and paler red spot on the belly. The male's nape is orangey red; females have much less red than adults on their crown.
