Measuring approximately 17 cm (6.7 inches) in length and weighing around 30 grams, this stocky antbird possesses a stout, strongly hooked, and chisel-tipped bill where the mandibles curve distinctly outwards then inwards, an adaptation almost unparalleled in the avian world save for its close...
This secretive antbird inhabits the dense understory of humid primary and mature secondary terra firme forests, often showing a preference for bamboo thickets and vine-laden tangles. It typically occurs at low elevations, generally below 200 meters (650 feet).
Its diet consists almost exclusively of insects and other arthropods, with a strong emphasis on beetle larvae and ants extracted from dead wood and bamboo. Foraging is done by using its specialized bill to pry open and chisel into decaying vegetation.
