Migration
Long-distance migrant. Chimney Swifts migrate to South America each winter flying across the Gulf of Mexico or skirting it along the Texas coast (a route they’re more likely to take in spring than fall). Many swifts use one of three distinct flyways: the Atlantic coast, the east side of the Appalachians, and the Mississippi River. They fly high in the sky during the day and roost in chimneys at night.
