Every fall, tens of thousands of Vaux's Swifts migrate south for the winter. Historically, these birds roosted overnight in hollowed-out old-growth redwoods, but as these trees have been lost, the swifts have adapted to using chimneys along the West Coast. The McNear Brickyard in San Rafael is home to three such chimneys and every September, between 25,000 and 65,000 Vaux's Swifts swirl overhead before funneling down into them to rest for the night.

You and up to four others can join GGBA trip leader Rusty Scalf for an exclusive behind-the-gates view of this breathtaking spectacle. Watching tens of thousands of birds spiral into a chimney at dusk is a truly singular experience. There is simply nothing else like it.

And to make sure you and your friends get a good luck at the swifts, this prize includes a new pair of Vortex Diamondback HD 10x42 Binoculars, with a Fair Market Value of $330!

The event will take place on Friday, September 18, from 6:00–8:00 pm. Bring lawn chairs and picnic fare and settle in for an unforgettable evening.

As an optional add-on, Rusty will lead a birding trip at Loch Lomond Marina Park beforehand for those who wish to make a full afternoon of it.

Note: In viewing the swifts with Rusty, you're getting to experience a little bit of Bay Area birding history. Rusty is the person who first discovered the swifts had turned the chimneys into one of their migratory roosts!
