Female. Resembles the male, but has the chin, throat, and breast barred like the remainder of the lower plumage.

The young have the upper plumage rufous barred with dark brown, and the lower plumage whitish, barred on the throat, breast, under tail-coverts, and axillaries with blackish. The young, however, vary extremely, and no description will cover all the changes they undergo from the nestling stage to the adult.
