Vaux’s Swift Roost Count
Portland Metro | Every Fall
Since 2009, Portland Audubon has been counting migrating Vaux’s Swifts at Chapman Elementary School and at a number of other sites in the Portland-metro region to monitor population trends of these exciting birds.
In addition to tracking local numbers, these counts contribute toward a larger Pacific Coast-wide effort to track this bird species, which has had a declining population trend in the Northwest over the past several decades. This project provides an easy way to contribute to bird conservation without leaving the city!
