This year's San Francisco count circle includes the north tower of the Golden Gate Bridge and all of San Francisco, and reaches down the peninsula to San Bruno Mountain and the wetlands north of the San Francisco International Airport.
Also blessed with a wide variety of habitats, the San Francisco count generally tops 160 species.
