The Bahama yellowthroat is 15 cm (5.9 in) long and weighs 15.1 to 17.3 g (0.53 to 0.61 oz). The species is sexually dimorphic. Adult males of the nominate subspecies G. r. rostrata have a wide black mask from their forehead around the eye to the side of the neck. Its top to rear have a thin grayish white border. Their hindcrown and nape are medium gray with a yellowish olive tinge. Their upperparts, wings, and tail are yellowish olive-green. Their throat is yellow and the rest of their underparts mostly a paler yellow with an olive wash on the flanks. Adult females have a plainer face than males, with a brownish crown, a thin grayish white supercilium, and grayish ear coverts. Their upper- and underparts are like the male's. Both sexes of all subspecies have a dark iris, a rather heavy black bill, and dusky pinkish legs and feet.

G. r. exigua: slightly smaller with a slightly smaller bill; darker upperparts; border around male's mask is thinner and usually broken on the forecrown; rest of crown is darker gray

G. r. coryi: brightest overall; mostly olive crown; mask border is yellow; flanks only lightly washed olive

G. r. tanneri: head pattern and flank wash intermediate between nominate and coryi
