Found at lower elevations near the mouths of mountain canyons, in arid scrublands and desert riparian areas, this hummingbird is readily attracted to hummingbird feeders. In natural settings, however, it feeds on flower nectar and insects and small spiders grabbed from leaf surfaces and flower petals. The tiny, thin-walled nest is made of grass and covered with small leaves and bark and held together with spider webbing. It is placed on small branches in low shrubbery or vines.
The four-digit banding code is BBLH.
