カタジロアリドリ Akletos melanoceps

Large, chunky antbird. Male is jet black with a small white shoulder patch (sometimes difficult to see) and blue skin around the eye. Female is a striking rufescent-brown with a black hood and blue skin around the eye. Occurs in pairs in the dense understory of forest in the lowlands of the Amazon basin, east of the Andes. Look for the tail being pumped down and raised slowly up. Listen for the loud, ringing song.
