Between 750 million to 1 billion birds are killed in North America each year as a result of collisions with artificial structures. Several hundred million collisions result from windows in buildings, particularly plate glass and other highly transparent or reflective glass. Unfortunately birds have not evolved to navigate an environment of transparent glass.
In response to this problem, Golden Gate Audubon joined with San Francisco, Oakland, Richmond and Alameda city planning staff and other conservation advocates to design and implement standards for bird-safe buildings.
The San Francisco Board of Supervisors approved Standards for Bird-Safer Buildings in September 2011, which were signed into law by Mayor Ed Lee in October 2011. You can read the San Francisco standards here.
The City of Oakland’s planning staff added Bird Safety Measures to their standard building permit requirements in June 2013. You can read about the Oakland measures on our blog or read the measures themselves here.
In 2016 Richmond approved Bird Safe Standards.
In 2018 Alameda approved Bird Safe Building Standards and a Dark Skies ordinance.
