Description
It has a total length of approximately 11 cm (4+1⁄4 in). Adult males have a relatively heavy black bill. The upperparts are black, except for a greyish rump (actually white finely streaked black, but only visible up-close) and two distinct white wing-bars (the lower often reduced). The underparts are white, except for a broad black pectoral collar (sometimes reduced and incomplete) and blackish mottling to the upper flanks. The far duller female has a brownish bill, dull buffy-olive upperparts and pale olive-ochre underparts. Juveniles resemble adult females.
