Look, More Swifts!

Some of the Vaux's Swifts that migrate through Oregon also roost in a large chimney in St. Johns. I don't know how many years this has been going on, but it astonishes me that I didn't know about it.
This chimney is in the St. Johns Twin Cinema building. Swifts used to roost in a chimney in nearby Kenton, too. I hear they no longer do, but you hear so many things. I wonder if all the great roosting spots have been spotted.
My Extra is a picture I found on the internet showing the inside of a chimney somewhere.
