This species primarily inhabits the dense understory and mid-strata of tropical and subtropical moist broadleaf forests, thriving from sea level up to approximately 1,600 meters in elevation. It particularly favors forest edges, natural gaps, and riparian zones within these ecosystems.
The Black-breasted Boatbill's diet consists almost exclusively of a variety of insects, including beetles, flies, moths, and caterpillars, which it catches primarily through aerial hawking and gleaning.
