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

Tennessee Warbler

Maps from eBird show where Tennessee Warbler have been spotted in August (left) and in January.

Despite being one of the most abundant breeding warblers of the Canadian boreal forest, relatively little is known about the breeding biology of 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 southerly push into the northern Great Plains, the Midwest, and the northeastern U.S., though some individuals linger within their breeding range from Quebec to 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-elevations in a variety of habitats like gardens, second-growth forests, and coffee plantations. Listen for the emphatic, staccato song of males in the spring (including migration) and occasionally in the fall, when some males also sing.
