Found primarily in dry to semi-humid deciduous scrub, thorny woodland, and riparian thickets, preferring dense undergrowth along watercourses within arid valleys. Occurs at elevations typically ranging from 300 to 1,200 meters above sea level.
Exclusively insectivorous, feeding on a wide variety of small insects and spiders gleaned from vegetation. Primary foraging method involves gleaning, hovering, and short aerial sallies.
