Spotting Birds at a Record Pace, with a Camera and a Bike

From SF Weekly,

San Francisco, despite being the western United States' most densely populated city, is also the heartland of a growing urban ecology movement that promises to become environmentalism's next wave. During the past 10 years, more and more locals have worked individually, formed groups, and then networked with other like-minded groups to restore, preserve, protect, expand, and proselytize about the pockets of natural ecosystems that exist within the city's gritty environs.

These local organizations, which now number at least 50, include homeowners in the western Sunset neighborhood working to establish a native plant species corridor that connects groups of endangered green hairstreak butterflies, and kids in the eastern Bayview-Hunters Point housing projects re-creating bayshore wetlands in the former industrial wastelands of Heron's Head Park.
