This species is a widely distributed and common summer resident of mature, mixed conifer-hardwood forests. The geographic range corresponds to the southern portion of the boreal forest region and the hemlock-white pine-northern hardwood and mixed mesophytic forest regions identified by Braun (1950).
Habitat: The Atlas Habitat Survey results generally agree with the large volume of literature suggesting that the bird occurs most abundantly in extensive tracts of mature, mesic mixed forests containing hemlock, white pine, or fir, and secondarily in mesic deciduous and pure coniferous forests. Numbers tend to be lower in pure deciduous forest. Although strongly associated with hemlock, the species also occurs in wet mixed forest that includes white cedar and black spruce.
While Morse (1976) found the number of Dendroica species closely related to physical characteristics of the forest, interactions among species may also influence habitat use within a given area.
Nests are usually found on horizontal limbs of a conifer 20 to 30 feet above the ground.
Habitat: Breeding: Usually in hemlocks, but sometimes in other northern conifers: pines, spruce, fir, and cedar. Rarely in maples, birches, and other hardwoods.
Special Habitat Requirements: Coniferous or mixed woodlands.
Habitat: Mainly conifers. Breeds mostly in coniferous and mixed forests, very locally in deciduous forest. Often nests around spruce, also in white pine, hemlock, red cedar, and jack pine. During migration, occurs widely in woodland and edges.
Diet: Insects, especially caterpillars. Feeds mainly on non-hairy caterpillars during summer, as well as beetles, true bugs, gnats, aphids, and others, also spiders. Takes poison-ivy berries and other berries in migration.
Nest: Sites are next to trunk where two or more small branches fork out of conifer, usually low (often a few feet above ground). Nest is open cup of twigs, grass, weeds, bark, spider webs, lined with plant fibers, hair, moss, and feathers.
