If you observe a bird collision or encounter a dead bird on Yale’s campus or in the greater New Haven area, please report it! This data is very helpful for identifying problematic buildings and facades.

In fall 2022 and spring 2023, we plan to conduct systematic carcass surveys on Yale’s campus to gather data on bird collisions. This data will inform our mitigation action plan. We are looking for volunteers to help monitor specific areas of campus for birds dead or injured due to collisions. Please email us if you’re interested in joining our volunteer monitoring team!

In addition to reporting collision victims, please consider collecting dead birds you encounter and donating them to the Yale Peabody Museum of Natural History’s ornithological collection. Preserved museum specimens are used for research and education. Instructions are available here:

If you know of a building on Yale’s campus that is experiencing frequent bird collisions, please let us know. We are compiling a list of buildings that are contributing significantly to bird mortality on campus, and are eager to hear from you.
