Found in the understory and mid-story of humid subtropical and tropical lowland evergreen forests, as well as adjacent secondary growth and forest edges. It typically occurs at elevations from sea level up to 1,500 meters.
Primarily insectivorous, feeding on small insects and spiders gleaned from leaves and bark. They forage actively by hopping and darting through the understory.
Spot-tailed Antwrens are highly active, diurnal insectivores, constantly on the move as they glean prey from foliage and small branches. They are frequently observed as key components of mixed-species foraging flocks, often leading or following, using the increased vigilance and foraging efficien...
