On the evening of September 7th 2014 Janesville (an official Wisconsin “Bird City“) had a “Swift Night Out” event.  860 migrating swifts were counted descending the chimney to spend the night at the Washington Elementary school before continuing their journey to South America.  Thanks to Joni Denker for sharing this impressive video on YouTube and posting on eBird.org.  Janesville’s Bird City Facebook page is here.
