POLICY TOWARD BIRDFRIENDLY LIVING ARCHITECTURE OVER ONE HUNDRED MILLION BIRDS ARE UNNECESSARILY KILLED EACH YEAR IN NORTH AMERICA DUE TO POOR DESIGN. HERE’S WHAT ONE CITY DID TO REDUCE THESE DEATHS By Kelly Snow 8 ach year, during the fall and spring migratory seasons, over one hundred million birds crash headlong into the sides of buildings in North America, and either perish immediately or upon hitting the ground. The Fatal Light Awareness Program (FLAP) a citizen’s group in Toronto, Canada has been working to rescue fallen birds in the early hours of the morning for more than a decade, and has successfully advocated for design and maintenance measures to reduce this unnecessary slaughter. In April 2005 Toronto City Council directed staff to develop means for incorporating the LIVING ARCHITECTURE MONITOR “needs of migratory birds into the Site Plan Review process with respect to facilities for lighting, including floodlighting, glass and other bird-friendly design features and that guidelines be established for that purpose.” Subsequently, a working group was formed that included local architects, developers, building management corporations, academics, bird advocacy groups and City staff. This stakeholder working group met several times throughout 2005 and compiled recommendations for Council’s consideration intended to reduce migratory bird deaths. The Bird-Friendly Development Guidelines (BFDG) were presented to Toronto City Council in March 2007 (available online at, and provide strategies to address the issue of bird collisions in two general categories – glass and light pollution. During daylight hours, collisions occur because birds cannot perceive images reflected in glass as reflections, and thus will fly into windows that they think are trees or sky. Clear glass also poses a danger as birds cannot perceive clear glass as a solid object. Birds will collide with clear glass while attempting to reach habitat and sky seen on the other side. The impact of striking a reflective or clear window in full flight often results in death. FALL 2009
