According to the American Bird Conservancy, up to one billion birds are killed by collisions with glass in the United States per year.  Other sources of collision mortalities are wind turbines, communications towers, and power lines.  Many of these birds are North American songbirds.  Zoos and aquariums use glass to present their exhibits for an enhanced guest viewing experience.  As conservation organizations, we have a responsibility to design our exhibits to be bird-friendly. Recently, AZA institutions have begun to take a leadership role in addressing collisions of wild birds with glass in their operations. This can be seen in the adoption of bird-friendly design strategies in new construction https://abcbirds.org/wpcontent/uploads/2019/04/Bird-Friendly-Building-Design_Updated-April-2019.pdf as well as the redesign of existing exhibits. There are simple and affordable strategies guests and their families can do to take an active role to protect birds at home. For example, putting up bird tape on windows at home is an easy action (https://abcbirds.org/program/glasscollisions/abcbirdtape/ or http://www.conveniencegroup.com/featherfriendly/feather-friendly ). We can model AZA values as we continue to integrate bird-friendly glass into the design of our newest buildings or to retrofit older buildings with bird-friendly products. It is a powerful message that together we can build bird-friendly architecture and educate millions of visitors each year on the glass strike issue, conservation implications, and the attainable solutions. 

Artificial Light At Night (ALAN) increases the risk of colliding with windows because birds can often become disoriented by lights in and around buildings and therefore fly closer to them. This confusion also affects migration. Turn off unnecessary lights at night, point any necessary lights towards the ground, and use motion-activated lights wherever possible. Several AZA institutions have also joined or created a Lights Out program in their area. Consider doing the same at your institution. Learn more about Artificial Light at Night from IUCN below.
