Medium-sized woodcreeper with a short bill. Found in the lower to middle levels of humid forests where it moves restlessly. Rather uniform rufous-brown overall with a brighter tail and a buff throat. Often associated with army-ant swarms and sometimes follows mixed-species flocks, but can also be encountered alone. The northern subspecies lacks the buff throat and has more rufous in the wings and tail.The song is a long (~60 seconds) series of “tchip-tchip-tchip” notes.
