Окулярек чорноголовий Rhegmatorhina gymnops

Fantastic-looking antbird with a bold whitish bare eye-ring and a restricted range. Males have a black head and breast, and are otherwise cinnamon-brown; females are duller around the head, but otherwise also cinnamon. Occurs in the understory of humid forest, where almost invariably found attending army-ant swarms. Song is a short series of high descending notes, ending in a harsh “churr.”
