The black-bellied caterpillar hunter is a small bird that lives in dense forests of South America. It spends almost all its time on the ground or in the lower forest layer and feeds on insects.
The black-bellied caterpillar hunter is distinguished by the black belly of males from other caterpillar hunter species. It helps control insect populations in forest litter and serves as prey for snakes and birds of prey.
