Range. - Western United States, breeding from southern United States, north to the Arctic regions, and from Kansas and Wisconsin westward. Winters in Mexico.
This bird is slightly larger than the last (7.5 inches long), and is rusty brown color on the belly and lower breast. Like the eastern Phoebes they are one of the earliest birds to return in the spring and are abundant in the greater parts of their range.
Like the latter, they often raise two broods a season, one in April and another in
July. Their nests are generally placed on narrow shelves and crevices of ledges, but they also nest as commonly about houses and farms as does the eastern bird. The nests are made of weeds, mosses, fibres and wool, and are quite flat. They lay four or five white eggs. Size .78 x .58.
