Abstract: There is now a large body of evidence that the Earth is currently experiencing a sixth mass extinction. While researchers, environmentalists, and conservation biologists can't agree on how many and which species we can save during this Anthropocene extinction, evidence exists that this mainly human-induced mass extinction is more robust than previously thought. This includes avian mortalities at man-made structures, especially from window collisions. This project is an evaluation on how to mitigate and reduce the numbers of migratory birds colliding with buildings/windows on UC's campus. Using the national avian literature, working with other universities experiencing this same problem, and utilizing programs like those of the American Bird Conservancy, we are currently working with UC administrators to pinpoint the mitigation practices that will best serve the UC community. We are currently trying to predict which bird-friendly designs would best fit UC and whether these designs would reduce avian collision mortality. The current mitigation practices used by UC include tinted glass windows, frit glass patterns, and a variety of bird-friendly designs. Unfortunately, of the more than 100 birds killed in 2018, three buildings on campus accounted for 49% of the mortalities and remain as good candidates for additional mitigation proposals and implementation of bird-friendly designs. If done properly and with administrative approval, then UC stands to benefit for another 200 years or more and standout as a leader in this sustainability initiative.
