[edit] Habitat

Wet forests in foothills and mountains between 600-2,200 m altitude.

[edit] Behaviour

[edit] Diet

The diet includes arthropods, and the larvae of wood-boring beetles. Foraging behavior is typical of furnarids - flies to a low position on a branch or tree trunk, and systematically scoots upwards probing for food.

[edit] Breeding

It places a few stems and roots in a hole 1.5-4.5 m high in a tree for its nest. The 2 white eggs are incubated by both sexes.
