The Tennessee Warbler is a fairly plain warbler,
common as a migrant through the state. Despite the name, the Tennessee
Warbler is only found briefly in that state during migration. It was named
by Alexander Wilson, who first found the species in the state of Tennessee in
1832. Populations
of Tennessee Warblers often fluctuate wildly, following cycles of high and low
spruce budworm populations.
Habitat
Generally found high in forested areas
during spring migration, lower during the fall migration.
Diet
Primarily insects, especially in
the summer. Will also eat nectar, berries, and occasionally seeds.
Behavior
Forages on the outer canopy of forest
areas, as well as in shrubby and weedy areas. Tennessee Warblers are
fairly gregarious, forming loose breeding colonies in many locations, and
often congregating in large groups during the winter months.
