The Yellow-throated Scrubwren is a small, ground-dwelling bird with a distinctive black face mask and forehead, which is bordered by a white and yellow eyebrow above and a bright yellow throat below. The crown and back are dark olive-brown, the underparts grade from the yellow throat to white on the belly, with the flanks washed olive. The wings are dark grey brown with the outer edges yellowish. The relatively long legs are cream to pinkish-grey and the bill is black. Females tend to have a brown face mask and forehead. Young birds are duller than adults in colour, with the underparts washed fawn.
