Washtenaw Bird & Nature Alliance and the City of Ann Arbor Natural Area Preservation invite you to join us for our Annual Ann Arbor-Washtenaw County Chimney Swift count. Watching Chimney Swifts enter their roosts at dusk is a spectacular sight (video and more information here). Volunteers will choose a known Chimney Swift roosting location and stake it out before dusk, counting the Swifts as they enter the chimney, as darkness falls. You can sign up for one night/one location at a time, or count each night of the weekend.
** New for this year** On Sunday night, August 24th we'll meet all together at the largest roost in the area-- usually this has been Mack School on Miller Rd. in Ann Arbor. We'll update this location closer to the event. It will be great to be together to see the spectacle. Arrive at 8 pm to see the Swifts begin to gather and stay until all the birds have descended into the massive chimney.
Chimney Swifts are in steep decline across North America, so let’s help find out how they are doing in Washtenaw County. Habitat loss is one reason, as well as decline of the insects they eat, and other unknown factors. We are helping bird science by conducting this count! This is a great experience for non-birders—bring your friends and family to show them how these very cool aerial insectivores share our cities and towns with us.
NOTE: Occasionally the Swifts will not use a particular location on a given night due to a predator such as a Cooper’s Hawk, or another issue. In that case, “No Swifts” will still be good information for us! Email Juliet Berger with your results after the survey, and post it on eBird if you have an account. Please share your eBird list with usernames Washtenaw Audubon Society and NAPBBS. Thank you for your help!
If you know of an active roost that’s not listed, email Juliet Berger [email protected] and she will add it to the sign up.
