The Tennessee Warbler is a small, rather plain warbler with olive-green upperparts, dull whitish underparts, and a gray head in males. It lacks prominent wing bars or bold facial patterns.
Where to spot
Breeds across the boreal forests of Canada and the northern United States. Winters in Mexico, Central America, and northern South America.
How to spot
During migration, it can be found almost anywhere with trees. Listen for its loud, rapid, three-part song: "tic-a-tic-a-tic-a, swit-swit-swit, chur-chur-chur." It often forages actively in the canopy.
When to spot
Best observed during spring (April-May) and fall (August-October) migration, when it can be found in a wide variety of wooded habitats. Breeding season (summer) in northern forests.

This species is known for its irruptive population dynamics; its numbers can boom in years when spruce budworm outbreaks occur, as these caterpillars are a primary food source.
