The crown is black, speckled with white; red forehead in males. The back is olive-brown; the underparts are white or cream, barred with black. The tail is black with a white central stripe. Short black beak. Nesting season: July to December in the north, and September to March in the south. Excavates nest in dry thin branches, 3-5 m above the ground; the cavity is 3-4 cm in diameter.
