Bird-Safe Buildings advance in Berkeley, Emeryville
By Ilana DeBare
The cities of Berkeley and Emeryville took major steps last month towards enacting Bird-Safe Building laws. Noreen Weeden, Director of Volunteers at Golden Gate Bird Alliance, has been instrumental in winning approval of such laws in San Francisco, Oakland, Richmond, and Alameda, as well as the pending Emeryville and Berkeley ordinances. Here we speak with Noreen about her Bird-Safe Building work that has put the Bay Area in the forefront of this important effort to save birds’ lives.
Q: What is the status of the Emeryville and Berkeley ordinances?
Noreen: In Emeryville, the planning commission will review an ordinance in February 2020 and then provide final language to the City Council, which has already agreed they want a Bird-Safe Buildings policy.
In Berkeley, the planning commission will review ordinance language that has already been drafted. The next step will be to make any requested changes, approve it, and implement it in 2020.

Q: How long have you been working on getting Bay Area cities to add Bird-Safe Building policies to their planning codes?
Noreen: We started in 2009. The way I got interested is that I was walking to downtown San Francisco, and on Third Street noticed a dead hummingbird. I wondered, ‘How did it hit the window and die?’ Then I noticed some resources from the American Bird Conservancy, which had just started writing articles about window collisions.
In San Francisco, we were talking at that time with the planning commission about the impact of nighttime lights on birds and promoting “Lights Out” guidelines for migration season. The commissioners were happy to hear about positive steps they could take, and said, ‘Come back to us with more things we can do.’ So we started talking to them about Bird-Safe Buildings.
Q: How big a danger to birds are window collisions?
Noreen: The U.S. Fish & Wildlife Service estimates that window collisions kill 1 million birds per day. That’s the low estimate; there are estimates that are higher than that. [Estimates range as high as 988 million deaths per year.] Often collisions occur where the windows are reflecting vegetation or the sky.
Q: Why do birds fly into windows so much?
Noreen: They don’t recognize glass as a solid, just as we don’t. We don’t like to admit it, but almost all of us have walked into a sliding glass door once or twice.…
