Do you hear chirping and rustling in your chimney? Do you notice birds flying in and out of your chimney around dusk each evening? Then chances are you have chimney swifts inside your chimney.

Chimney swifts are migratory birds that spend summer in the northeastern United States before flying to Peru for the winter. Chimney swifts build their nests on protected vertical surfaces. Their preferred nesting location — hollowed out trees — is a scarcity in many areas. So they have adapted to make their homes on the inner walls of masonry chimneys, which is the perfect surface for constructing nests from twigs.
