HABITAT: Prefers shrubby sites or low- to intermediate-density forests with substantial shrub understory; generally avoids forests with a high percentage of canopy cover. Occurs in a variety of habitats, from montane chaparral to moderately dense lodgepole pine forest, including many montane conifer types and aspen; especially favors mixed woodlands or edge of small conifers and brush. In general, prefers drier, more open or patchier forests than Hammond's flycatcher.
NEST: Builds nests on upright or pendant twigs or in crotches of low shrubs or trees in relatively dry sites. Usually nests 3 to 8 feet, but up to 40 feet, above the ground in willow, alder, aspen, and other trees and shrubs.
FOOD: Forages low over shrubby vegetation for flying insects.
