Spring Birds: When Does Spring Migration Begin?

Bird watchers anticipate spring migration like kids anticipate Christmas. Looking forward to first-of-year species helps us make it through the bleak days of late winter. But when does spring migration actually start? For the past 35 years, I've lived and watched birds in the lower Midwest—southern Ohio and southern Indiana. If you live in New England, the Great Plains, the Rockies, the Pacific Northwest, the Southwest, or the South, your spring birding experience will probably be quite different in terms of the species and/or timing of their return.
