Males exhibit a vibrant yellow plumage covering the head, breast, and underparts, sharply contrasted by a black face mask, throat, and bill, with an olive-green back and wings. Females are more subdued, appearing duller and streakier, lacking the prominent black mask of the male. This species typi...
