Tennessee Warbler
Vermivora peregrina
Description
A grey crown,
olive green upperparts, white underparts, blackish eyestripe and white
line above the eye are features that distinguish the Tennessee Warbler.
Habitat
The preferred
habitat is found in the open deciduous, mixed and coniferous forests boreal
zone with Engelmann spruce, balsam fir, grasses, dense shrubs and scattered
clumps of young deciduous trees.
Song
The Tennessee
Warbler is a highly vocal species in which only the male sings, with a
loud and determined staccato 3-part song as represented by "ticka ticka
ticka ticka, swit swit, sit-sit-sit-sit-sit-sit" or "sidit-sidit-sidit-sidit-swit-swit-sit-sit-sit-sit-sit-sit."
It is the song of the Tennessee Warbler that often signals in eastern
North American the peak of spring songbird migration.

Comments
The Tennessee Warbler is described as a quick, nervous and active species that is a spruce budworm specialist and favours nectar and fruit during the winter season.
The Tennessee Warbler's transient breeding fluctuations are directly related
to outbreaks of the Spruce Budworm.
The nest of the Tennessee Warbler is remarkably concealed by sphagnum
moss and the bird's tendency to build nests at the base of small shrubs
and trees.
