Breeds in higher elevation coniferous forest edge with meadows or pastures. Typically seen sitting on low fence wire, posts or the ground, in the summer this bluebird catches insects like a flycatcher in the air or swoops down on them on the ground. In the winter it often forms large, loose flocks that move through agricultural fields, grassy prairies and open habitats at lower altitudes. Here it adds fruits to its diet. The low to medium height cavity nest is filled with a grassy floor mixed with pine needles and small twigs. It readily uses nest boxes if available.
The four-digit banding code is MOBL.
