Chimney Swifts, Wartburg Theological Seminary, Dubuque, Iowa
Tonight was a pop-up birding event, made public by Marty Corfman, a very active member of the Audubon Society, at the Wartburg Theological Seminary in Dubuque, Iowa. We were able to see hundreds of Chimney Swifts circle around the tower of the seminar and finally pour into an old chimney after sunset. I’m sure everybody who joined this event enjoyed it and was touched by watching the swifts showing up one after another and entering their roost for the night. Thank you Marty for the invitation!
The Chimney Swifts will depart soon for the tropical areas in South America, where they will spend the winter. I shot a number of still images, like the one above, but also recorded a short video sequence. Feel free to click the video link below.
