Chimney Swifts Love to Fly
Chimney swifts are very fast fliers and spend most of their lives in midair. They eat, drink and mate while flying, only stopping to raise young. They even take their baths in flight by dipping in a water source briefly. It’s estimated they fly more than 500 miles each day. Chimney swifts are small birds, only about 5 inches in length, that look somewhat like swallows and are sometimes mixed in with flocks of swallows. They are often referred to as “flying cigars” because they look like fat cigars with wings flying high above us! You may hear the distinctive twittering call of a swift bird before you look up to see it flying above.

Chimney Swifts Are Losing Nesting Sites
Unfortunately chimney swifts are a species of conservation concern. They originally nested in old tree stumps then wood fence posts. After eastern forests were cut down and wooden fence posts went to the wayside, they adapted to nesting in chimneys. Now, however, chimneys are often not included in new buildings and many with chimneys have caps on them so a swift bird cannot enter to nest. There are a number of efforts to provide artificial nesting sites by building chimney swift towers.
