rustkronetreløper Dendrocolaptes hoffmannsi

Large woodcreeper with a strong black bill. Dark chestnut-brown overall. Note the very fine bars on the head and underparts and the cinnamon crown. Found in the interior of humid forest and second growth, sometimes venturing to the forest edges, and regularly attending army-ant swarms. The song is a rolling series of “wutwutwut…” notes like the song of the closely-related Black-banded Woodcreeper, but the two probably don’t overlap in range. The similar Amazonian Barred-Woodcreeper has a dark red-brown bill.
