Every year in Portland, the Vaux Swift's put on a show in a quiet NW neighborhood right before dusk. This year was the first time we had the pleasure to witness one of nature's equinox treats. It only occurs at this time of year before these little birds migrate south for the winter. The birds found the chimney at Chapman school in the 80's for their evening roost and have been back every year since then. Here are a few photos from Sunday night. Thanks Rand for taking us to the Chapman school to see this for ourselves (so much fun).
