Seeking Swifts

Launched five years ago, Vaux's Happen-ing enlists volunteers to locate, observe, and gather data about communal roost sites used by Vaux's Swifts in migration. Chim- neys have proved to be among the most significant sites. Vaux's Happening quickly expanded into an effort to raise awareness of and try to preserve as many sites as pos- sible. Over the last 10 migrations, observers have documented nearly four million Vaux's Swift roosting events from San Diego to the Yukon. Here in the immediate Bay Area, the swifts roost in a stack at the McNear brickyard in San Rafael. Larry Schwitters will talk about this ongoing citizen science project and share images captured by chimney surveillance cameras. He will also touch on his search for waterfalls in the Pacific Northwest that host nesting Black Swifts.
