A Board of Supervisors committee has approved a plan to require new buildings to have treated glass or other measures to keep birds from banging into them, reports KCBS. The full board votes next week, with architects and developers complaining about the potential added expense. "This sounds like an 'only in San Francisco' kind of thing," writes Carolyn Tyler of KGO, but cities such as Toronto and Chicago have similar measures in place.
