Tennessee Warbler

This bird is found in Tennessee only briefly, during spring and fall migration; it lacks a more descriptive name as it is relatively nondescript. The male Tennessee Warbler makes up for his plain appearance with a strident staccato song, surprisingly loud for the size of the bird. Nesting in northern forests, the Tennessee Warbler goes through population cycles: it often becomes very numerous during population explosions of the spruce budworm, a favored food.
