Chimney Swifts can be found throughout the eastern United States. Their name comes from their common use of chimneys and similar vertical structures for nesting and roosting. Historically, Chimney Swifts nested in large hollow trees, but habitat loss and the decline of old-growth forests led them to increasingly rely on human-made structures. Today, many Chimney Swift populations depend almost entirely on chimneys, towers, and other suitable vertical spaces.

Across their range, Chimney Swifts have experienced significant population declines. At Westcave, the creation of nesting and roosting structures supports broader conservation efforts by providing suitable habitat, allowing for continued monitoring, and creating opportunities for public education. These structures also help highlight the ecological importance of Chimney Swifts as insectivores, as they consume large numbers of flying insects while in flight.
