The bicoloured antbird is an obligate ant-follower.. Ant followers are birds that feed by following swarms of army ants and take prey flushed by those ants. [1] The best-known ant-followers are 18 species of antbird in the family Thamnophilidae, but other families of birds may follow ants, including thrushes, chats, ant-tanagers, cuckoos, motmots, and woodcreepers.
The ant-following antbirds are themselves followed by three species of butterfly in the family Ithomiinae which feed on their droppings. [34] Bird droppings are usually an unpredictable resource in a rainforest, but the regular behaviour of ant followers makes the exploitation of this resource possible.

The white-chinned woodcreeper is an obligate follower of army ant swarms. It typically perches on a branch or clings to a trunk near the ground and makes short flights to capture arthropod prey disturbed by the ants. It does not feed on the ants themselves. It does occasionally also take small vertebrates as they flee the ants.
The black-spotted bare-eye is an obligate ant follower that feeds on a variety of arthropods that flee foraging army ant swarms. It typically forages individually, in pairs, and in family groups, perching within about 1 m (3 ft) of the ground and sallying or pouncing to the ground after prey.
The species in this genus are specialist ant-followers that depend on swarms of army ants to flush insects and other arthropods out of the leaf litter. [2] The genus was erected by the French ornithologist Louis Pierre Vieillot in 1818. [3] The type species is the white-plumed antbird (Pithys albifrons). [4] It contains two species: [5]
The pale-faced bare-eye is an obligate ant follower that feeds on a variety of arthropods that flee foraging army ant swarms, primarily those of Eciton burchelli. It typically forages individually, in pairs, and in family groups, perching within about 1 m (3 ft) of the ground (though sometimes as high as 3 m (10 ft)) and sallying or pouncing to ...
The ocellated antbird is an obligate ant follower that feeds on arthropods that flee foraging army ant swarms such as those of Eciton burchellii. It typically forages in pairs or family groups, perching within about 1 m (3 ft) of the ground, often near the front of the ant swarm, and sallying after prey.
