This large oropendola lives in the lowlands of Chocó, northwestern Colombia. Records place it in humid forest and forest edge up to about 365 m.
Males are about 46.5 cm long and females about 40 cm. The head and underside are black, the back, flanks, and closed wings chestnut, the cheek skin pink, and the tail yellow with black central feathers.
It eats fruit and insects and has been recorded in groups of about 2–10 birds in the canopy. Older observations describe birds in tall trees along rivers.
