Each September, 25,000 Vaux Swifts make a Chimney located at Chapman Elementary School in Portland, Oregon their home.
As they migrate in their route to a southern, warmer climate for the winter, they make the month of September as their home. They are native to the Pacific Northwest, but are migrating birds.
Vaux Swifts are the smallest Swift, and consist of eating little bugs.
With our classic Indian Summers-- hot, hot days, and cool, cool nights . . . the bugs are out en masse . . . so are Spiders . . . and so are Vaux Swifts!
Since the late 1980's the Chimney at Chapman Elementary School has been the place where the Vaux Swifts have come home to roost (sleep) during the night. I'm wondering if they came to Portland in the '80's after Mt. St. Helen's blew her top? Only conjecture . . . but I do wonder why the swifts started coming here in the 1980's.
The Audubon Society -- Swift Watch 2009 -- has a nice website dedicated to the Vaux Swifts and they offer free guides, binoculars and lessons during the month of September at Chapman Elementary School. http://www.audubonportland.org/local-birding/swiftwatch
