Fatal bird window collisions are often overlooked as minimally damaging to bird populations or viewed as inevitable collateral damage of human habitat expansion. In reality, these unnecessary collisions are truly monumental in number, and prove to be a serious threat to bird populations, especially endangered bird species. In the United States alone it is estimated that between 365 - 988 million birds fatally collide with man-made windows annually. We are focusing our study on fatal bird-window collisions occurring on the Classroom and Student Services Building (C&SS building) at the USU campus in Brigham City, UT 84302. We have selected this building as a potential location for a high frequency of bird-window collision for its inclusion of multiple large windows. Several studies have indicated that window area was positively correlated with the amount of window strikes. The objective of the study is to: Investigate the number of fatal bird window collisions that occur on the C&SS building, then determine if it is larger than the expected number of fatal window collisions per month for a low-rise non-residential building. The expected number is between 0 – 6 collisions per month. The objective will be accomplished through a two-step method. First, we will be analyzing data obtained through the conduction of daily surveys of the C&SS building during the months of August through November of 2020. The surveys will be conducted by ourselves and USU faculty. We will be looking for bird-window collision evidence. Finally, we will be collating our survey data with survey data obtained in the in the years 2017-2019.
