Together with the Princeton Birding Society, the CST and the Office of Sustainability, we are monitoring campus buildings in an effort to quantify bird collisions with glass windows. These data—collected primarily during the spring and fall migration periods—are guiding discussions on campus about which buildings are the most problematic and could be treated with bird-friendly film, like the dotted film applied in 2022 to the Prospect House dining room (shown in the photo on the right). You can read more about the bird-proofing of Prospect House here.

The data we are collecting is being compiled and analyze to provide guidance about necessary treatments of campus buildings that prove to be particularly dangerous for birds. Take a look at some of our preliminary data of recorded bird collisions during the 2023-24 migration seasons.
