Global Habitat Comments: Open and partly open country, especially savanna, agricultural lands, and areas with scattered trees (AOU 1983), also desert. In western Nebraska, used habitat types have large, widely spaced cottonwood trees with abundant grass cover below (Bergin 1992). BREEDING: Nests in trees (usually out on a limb, sometimes near trunk); may also nest on shrubs, fence posts, or buildings. Nest usually about 4.5-9 m from ground. In Nebraska, nests in larger, taller trees with more available perches (Bergin 1992).
Food Habits: Invertivore: Adult, Immature
Global Food Habits Comments: Primarily insectivorous; feeds on wasps, beetles, moths, caterpillars, grasshoppers, true bugs. Also eats spiders, millipedes, and some fruit. May occasionally take tree frogs (Terres 1980). Catches insects in the air or on the ground.
Global Phenology: Diurnal: Adult, Immature

Global Range Comment: BREEDING: southwestern Canada south to northern Baja California and northwestern mainland of Mexico, and west-central Texas, and east to northwestern Ohio, rarely to north-central Missouri.
