Both sexes have grayish white feathers around the eye, with the female's more extensive. Adult males have a chestnut head and brown back, rump, and wings. The rump has fine black vermiculation. The throat and undersides are rufous. The adult female's crown is dusky brown and its breast and belly are dark gray. The juvenile is similar to the adult female.
