The Black-throated Blue Warbler is a common migrant in the
eastern United States, but is normally only a rare stray west of the
Mississippi. The males are striking and distinctive, with dark bluish
upperparts, a black face and throat, and white underparts. Females are
much plainer, with a olive-gray body. They are often more easily observed
than many warblers due to their tame nature, although their preferred habitats
often are dense thickets.
large tracts of deciduous and deciduous/conifer mixed forests for breeding,
especially if there is a dense shrubby undergrowth. During migration, they
also are most often found in forested and brushy locations. In the winter,
they are found in dense tropical forests as well as more open areas such as
fence rows and suburban areas.
Diet: In summer, primarily
feeds on insects and spiders. In winter, insects still make up a large
portion of the diet, but they also will feed on fruits, berries, seeds, and
Behavior: Forages deliberately in the canopy,
taking insects from the surfaces of leaves and branches, hovering and
gleaning insects from vegetation, or occasionally flitting out to capture
insects in mid-air.
Breeding: Non-breeder in South Dakota
Migration: Summers in the Appalachians, New England, the Great Lakes region, and
southeastern Canada. Winters in southern Florida and the Caribbean.
Similar Species: Males are generally distinctive, with a possible confusion with the
Warbler. Females may be confused with Tennessee
Warblers or Orange-crowned Warblers.
Feeders: They will come to
feeders for suet and peanut butter in migration. They also will
occasionally feed on nectar offered at hummingbird feeders.
Conservation Status: They require large tracts of
forest land for breeding, and have declined in parts of their range due to
