Tiny bird of forest canopy; best identified by stub-tailed appearance, conical bill, and behavior. Occurs in upper levels of rainforest and patches of tall forest in savanna regions. Often found with mixed-species flocks. Taps vigorously into fine dead twigs and vines, often hanging upside-down at the ends of branches. Similar to White-barred Piculet but occurs in different habitat and has finer barring on belly, giving an overall darker appearance. Most frequent call is two soft squeaks, the second lower-pitched.
