The White-chinned Woodcreeper lives low in humid Amazonian forest and is strongly associated with army-ant swarms, catching arthropods disturbed by the ants rather than eating the ants. A white chin is useful, but iris color varies among subspecies.
Reported length is roughly 16–21 cm. Plumage is mostly unmarked chestnut to reddish brown, with a narrow white stripe on the chin. Iris color varies among subspecies from reddish-brown to grayish-blue.
It is an obligate follower of army-ant swarms. Near the ground it makes short flights from trunks or branches to catch arthropods flushed by the ants; it does not eat the ants themselves. Breeding biology remains poorly known.
An extinction-risk assessment has not been added yet.
