Habitat
Breeds in deciduous and mixed deciduous-coniferous forests with understory of shrubs (Stewart and Aldrich 1952, Lawrence 1953, Southern 1958, Barlow and Rice 1977, Graber et al. 1985). More abundant in interior forests than forest edges (Graber et al. 1985). Also, breeds in alder and aspen in northern areas (Barlow and Power 1970). May be found in residential areas, city parks, and cemeteries where large trees occur (Tyler 1950, Graber et al. 1985). In Alaska, found in black cottonwood forest groves and riparian alder thickets. Species thought to breed mainly along the large river systems on the mainland and possibly on islands near the mouths. In B.C., this species breeds from sea level to 200 m on the coast and from 300 to 800 m in the interior (Campbell et al. 1997).
