In On the Move, our regular migration column, we feature pairs of eBird distribution maps that you can use to compare where interesting birds are at different times of the year. We featured the Tennessee Warbler, pictured above, in our July/August 2018 issue.

Tennessee Warbler

eBird maps show where the Tennessee Warbler was spotted in August (left) and January.

Although one of the most abundant breeding warblers in the Canadian boreal forest, relatively little is known about the breeding biology of the Tennessee Warbler, likely due to the inaccessibility of its breeding grounds and the difficulty of finding its nests. In August, the species shows a marked southward push toward the northern Great Plains, Midwest, and northeastern United States, although some individuals linger in their breeding range from Quebec to the Yukon . In January, during the non-breeding season, the Tennessee Warbler is common and widespread from southern Mexico to Colombia, where it occurs from sea level to mid-altitudes in a variety of habitats such as gardens, secondary forests and coffee plantations. Listen for the emphatic, staccato song of males in spring (including migration) and occasionally in fall, when some males also sing.
