A small flocking bird of scrub and grasslands. Note the dark face (black in males and gray in females) that is surrounded by a swirl of yellow from behind each eye, down the sides of the neck, and across the chest. The male Yellow-faced Grassquit has a passing resemblance, but the throat is yellow and the chest is black. Female Yellow-faced and Black-faced Grassquits are of similar size and color but lack the yellow neck and chest seen on Cuban Grassquits. The call is a sharp musical chip and the song is a rather high-pitched twitter.
