Chimney Swift Recovery Project

Stay alert in your neighborhood and report Chimney Swifts to Audubon Vermont using eBird!

Audubon Vermont is working with the Vermont Fish and Wildlife Department to monitor Vermont’s Chimney Swift population. Chimney Swifts are considered a “Species of Greatest Conservation Need” by the Vermont State Wildlife Action Plan, due to their population declines both in Vermont and throughout their entire range, and they are protected by Federal law under the Migratory Bird Treaty Act of 1918. 

Their alarming decline is largely due to a loss of habitat and thereby roosting and nesting sites. Chimney Swifts rely on masonry and flue-tile chimneys during nesting and migration seasons. Chimney Swifts historically used large, hollow trees for nests and roosts, but as the old forests were cut down, they learned to use chimneys and other structures. Now, Chimney Swifts rely almost entirely on human-made structures for nest sites. Because they cannot perch like songbirds, Chimney Swifts need deep shafts in which to raise their families and roost at night. Unfortunately, many chimneys have been capped or removed, which has reduced the number of sites swifts can nest and raise young. Consequently, Chimney Swift populations are steeply declining, with a 53% percent drop between 1966 and 2007 in the United States

Participate in our Chimney Swift surveys this summer. 

Visit Chimney Swift Survey 2020 and 10 Easy Steps for Submitting Chimney Swift Surveys to Ebird​ to get started! 

This summer’s survey is focused on identifying critical nesting and roosting habitats in 2020.  Please submit any sightings you have, but more importantly, we would appreciate any reports of where birds are entering chimneys or other structures in the various towns and cities.

Chimney Swift Birding Buddy Program

We recognize that safety in the outdoors while birding and monitoring is not equal for all of us. Birders in the BIPOC community, LGBTQIA+ birders, female-identifying birders, and birders with disabilities all face additional barriers to being safe and accessing opportunities to participate in Audubon's community science work.  

We want to be sure that everyone is safe when out surveying for Chimney Swifts, especially since this year's monitoring protocol is focused on finding Chimney Swift nesting and roosting sites at dusk. If you are interested in participating in Chimney Swift monitoring, we recommend that you go out with a birding buddy.  

Audubon Vermont is coordinating the matching of Chimney Swift monitoring birding buddies. You can either request a birding buddy or volunteer to be a birding buddy by filling out a brief online form to provide us with your name, email address, and town. When you request a birding buddy we will get you in contact with someone who has offered to join other birders in your area. We will not share this list with the public, but will reach out privately to individuals. Click here for more information or to sign up.

What Else Can I Do to Help Chimney Swifts?

  • Keep masonry or clay flue-tile chimney tops open and dampers closed from March through October to provide the opportunity for Chimney Swifts to nest.
  • Have your chimney cleaned in early March before the Chimney Swifts return from their winter home in South America.
  • Metal chimneys should be permanently capped to prevent birds and other wildlife from becoming trapped.
  • Email us at mfowle@audubon.org if you are interested in working with local conservation groups to construct Chimney Swift Towers in your area.
  • Educate your friends and neighbors about Chimney Swifts.

More about Chinmey Swifts

The Chimney Swift is one of four species of swifts found in North America (Black Swift, Vaux’s Swift, and White-throated Swift are the others), and the only one found in the Atlantic Flyway. Chimney Swifts breed in the central and eastern United States and winter in the Amazon basin of Peru, northern Chile, and northwest Brazil. Adult Chimney Swifts are most often seen in groups in flight. When soaring, their long pointed wings support a short, wide body with a squared-off tail. Some folks say they look like “flying cigars” because of their body shape. Chimney Swifts' flight is accompanied by loud, chattering twitters. Both adult males and females are identical in appearance: sooty-gray to black with silvery-gray coloring on their neck. Both sexes. Their long wings cross over the tail feathers, which are tipped by pointed bristles. These tail bristles and claws are used to cling to rough vertical surfaces.

 Fun Facts About Chimney Swifts:

  • Chimney Swifts eat nearly one third of their own weight every day. These “aerial insectivores” devour flying insects, including mosquitoes, biting flies, and termites. 
  • Chimney Swifts are an important component of Vermont’s biodiversity, and their populations are declining range-wide (see more details below).
  • Chimney Swifts’ aerial acrobatics and interactions with each other are spectacular to watch.    
  • Chimney Swifts have some amazing adaptations: they can “sleep” in flight; often young swifts do not stop flying for their entire first year. 

 

About the Artist

About the artist: My name is Katie Kennedy and I lived in Vermont for four years while studying Wildlife Biology at the University of Vermont. It was during this time that I learned about birds and bird watching, and I quickly found that I was even dreaming of seeing birds. I used drawing and painting as a way to understand birds more and improve my identification skills, and soon it became very natural to create artwork that was completely inspired by my love of birds. Although I love the excitement of spotting a rare bird, the familiar and common species, like the American robin, bluejay, and chimney swift make a connection to wildlife accessible to everyone. To me, chimney swifts invoke a feeling of summer in Burlington, comparable to creemees and sunsets over Lake Champlain. Their quiet chatter and whimsical flight patterns bring a smile to my face, and allow me to dream of soaring and gliding through sunny streets.
