What is a Chimney Swift?

Basic IDSwift1

Chimney Swifts are dark gray-brown, swallow-like birds with long, slightly curved wings and stubby tails.  They fly with stiff, rapid wing beats.  Their call is a series of quick, chittering noises.

Activity

This small bird spends almost its entire life in flight, feeding and drinking on the wing.  Chimney Swifts nest and root in chimneys and on vertical surfaces in dim, enclosed spaces.  On migration in spring and fall, swifts can be seen at dusk swirling into large chimneys by the dozens or even thousands to roost for the night.

Why Care About Chimney Swifts?

  • OLYMPUS DIGITAL CAMERAChimney Swifts have declined significantly in recent decades and need our assistance more than ever. In 2009, our northern neighbor, Canada, listed them as Threatened.
  • Because of changes made to our landscape and loss of historical habitat, swifts rely almost entirely on man-made structures for nest and roost sites. Our chimneys are their homes.
  • Chimney Swifts eat up to half of their own weight in flying insects, including pests, every day.
  • Chimney Swifts are protected by Federal law under the Migratory Bird Treaty Act of 1916.
  • Like watching a beautiful sunset, the aesthetic value of observing Chimney Swifts’ aerial acrobatics and interactions is a simple pleasure of nature.

How Can I Help?

  • OLYMPUS DIGITAL CAMERAIf you have a masonry or clay flue-tile chimney, keep the top open and the damper closed from April through October to provide a nest site for these insect-eaters. Metal chimneys should be permanently capped to prevent birds and other wildlife from being trapped.
  • If you have your chimney cleaned, do it from November to March before the Chimney Swifts return from their winter home in South America.
