September begins the fall migration of Vaux’s Swift through Marin County Marin Audubon and the Bay Area Vaux’s Swifts Working Group are expanding efforts to count Vaux’s Swifts and are seeking new volunteers with various abilities to join in the effort through this Workshop.  This is part of a wide effort to understand the largely unknown movement and roosting patterns of Vaux Swifts. We invite you to join us for this exciting citizen science opportunity! Volunteers will engage with knowledgeable Vaux’s Swift counters/members of the Working Group who bring years of experience to share with newly-motivated  birders. Volunteers will learn about and participate in refining the methods used to count these large congregations of Vaux’s Swifts and plan future counting activities. The Workshop has two parts: -  Thursday, September 5th - 7PM  - a meeting on Zoom at which you will hear an overview of the  conditions at the overnight roost areas, efforts to count the swifts at this local site, and the various ways you can help.
