SFBC Rec Ride: San Francisco Birding by Bike

"Join SFBC members Annie & David Armstrong for a pedal-powered introduction to San Francisco's avian life. The ride will look for some of the more than 300 resident, migrating and overwintering bird species that can be found in SF, proceeding at a relaxed pace through Golden Gate Park, on Ocean Beach and around Lake Merced where you'll look for ducks, waders and shorebirds."
