Every year around September, thousands of swift came roost at the chimney of the local elementary school: Chapman. Audubon Portland publishes a swift count during the month. I decided to check it out this Thursday evening. They started showing up shortly before sunset, and flying around for at least 20 minutes before slowly finding some order to go down the chimney. Lots of people brought picnic dinner. It smelled of food, and made me very hungry.
