Рыжеспинная муравьянка Drymophila rubricollis

Medium-sized antbird with a long, dusky-colored tail and an orange-rufous body that contrasts with its dark mask, white eyebrow, and white cheeks. Males have a black crown, which is brown in females. Very similar to Ferruginous Antbird, but Bertoni’s have more black on the back and females have a brown (not gray) crown. Found in the lower and middle levels of wet forests with bamboo. The song is a nasal series of descending notes.
