It creeps up trunks to find small spiders and insects, extracting its prey from the bark. Gleans from bark surface, scrapes insects from moss, and hammers shallowly into bark. Usually in pairs and often accompanies mixed-species understory flocks.

Breeding

It builds a cup nest in a narrow tree cavity and 2 white eggs are laid. Time of breeding season varies regionally.
