Bird Safe Philly tracks window collisions in the city using the iNaturalist website/app. To add your observations or to see others’ observations, visit this site or download the iNat app on your smartphone.
Data collected through this project will help to identify which buildings pose the greatest threats to birds, provide information on the timing of collision events, and show which species are most affected. This data will inform the development of Bird Safe Philly’s Lights Out program and other measures to prevent bird deaths, and to assess the effectiveness of these measures.
