Chimney swift slumber party

September 22, 2009

It’s a chimney swift slumber party every night in September at Chapman Elementary School in Portland. Since the late 1980s, Vaux’s Swifts have used the school’s smokestack as a roosting spot during their fall migration to southern Central America. As many as 35,000 of the small black birds circle the chimney each evening around sunset and then pack in to spend the night.

Some friends and I wanted to see it all go down. We arrived by bike around 6:45 p.m. and positioned ourselves among many others on the grassy hillside overlooking the school. Members of the Audubon Society of Portland stood by to loan out binoculars and answer all swift-related questions, and a neighborhood boy sold his mom’s chocolate chip cookies at a stand across the street.

Munching, we waited for the spectacle to start.

The birds arrived one or two at a time at first, but after a while, they came in droves and filled the sky. They swooped and rose, dipped and dove and eventually took up a counterclockwise direction, circling again and again above the smokestack. Then, as if on command, a segment of the flock began spiraling into the chimney like coffee grounds in a draining sink.

The birds continued funneling into the chimney on and off for about half an hour, majorly interrupted only once when a hawk swept in and picked one off. (Is fishing in a barrel really fair?)

Eventually, only a few dozen birds remained outside. The group tried diving into the chimney once, twice, three times, but without success. It was full. After a few more attempts, the birds gave up and flew west toward Forest Park to fend for themselves.

The audience applauded, and the show was over. Until the next day.
