The Tennessee Warbler is a small, plain songbird with olive-green upperparts and whitish underparts, featuring a thin pointed bill perfectly suited for gleaning insects from foliage. Despite its name, this warbler breeds in northern forests and only passes through Tennessee during migration, making it a common but often overlooked spring and fall visitor throughout eastern North America.

How To Identify

A small passerine bird of about 4-5 inches in length. It is characterized by its general dull olive coloration across the back and wings, contrasted by a noticeable yellowish wash on the flanks and breast.

Habitat

It breeds in boreal and mixed forests of northern North America, particularly in spruce-fir and aspen woodlands, and winters in humid montane forests of Central and South America.

Behaviour

Tennessee Warblers are remarkably active foragers that often glean insects from foliage with acrobatic movements, and they are known for their persistent, simple song that sounds like a rapid 'chip-chip-chip-chip.'

Did You Know?

Despite its name, the Tennessee Warbler breeds primarily in Canada and has no special connection to Tennessee; it was simply first described from a specimen collected there. This tiny warbler weighs less than a dime yet undertakes one of the longest migrations of any songbird.
