But imagine this, if you will: twilight on a steep slope, tucked up against Portland's West Hills. Hundreds of people, young and old, families, couples, and babies with strollers, bikes, and dogs, all spread out on the grass. Many are having al fresco dinners ranging from gourmet feasts to cheap pizza. Everyone is chatting and laughing, kids are running around and rolling down an empty part of the slope. People squeeze in politely to place a blanket down and claim their tiny space before the show gets started. The sun sinks lower in the west and suddenly there's a buzz in the air as people start to exclaim "here they come!".
Tiny Vaux's Swifts roost by the thousands in a tall brick chimney which was formerly part of the heating system at Chapman Elementary School. During the month of September, the swifts arrive as part of their annual migration. The birds used to use cavities in old growth trees but apparently an old brick chimney is a workable modern day substitute because an astounding number of birds show up, year after year.
They begin coming in from all directions as the sun sets. The numbers aren't impressive initially and first-time visitors tend to wonder what all the fuss is about (and might be more firmly convinced that Portlanders are nuts). Before too long, however, the numbers increase dramatically and thousands of birds start to swirl around the chimney. Often a hungry raptor will show up for an easy meal but they must have been well fed this year because we saw no sign of any hawks. Sometimes the tiny swifts do manage to chase them off but last night it wasn't necessary.
