Chestnut-sided Warblers winter in southern Mexico and Central America and take a direct flight across the Gulf of Mexico to their nesting areas which includes the upper Midwest and northeastern U.S. The birds nest in leafy second-growth woods, clearings, and thickets. I saw Chestnut-sided Warblers in several locations during a week-long birding trip to Michigan and Minnesota earlier this year. These are the best of the many photos I took of this beautiful bird. The bird was in deep shadow and/or partially obscured in most images.
