Bird-window collisions are a major source of human-caused mortality for which there are multiple mitigation and prevention options available. Despite growing availability of products designed to reduce collisions (e.g., glass with etched patterns or markers and films adhered over existing glass), few replicated field tests have been conducted to assess their effectiveness after installation on glass. We conducted a field study to evaluate the effectiveness of a commercially marketed product (Feather Friendly markers) in reducing bird-window collisions at glass-walled bus shelters in Stillwater, Oklahoma, USA. This study included a before-after control-impact (BACI) analysis comparing numbers of collisions at 18 bus shelters in both pre-treatment (2016) and post-treatment (2020) periods, and an analysis comparing 18 treated and 18 untreated shelters during 2020. For the BACI analysis, collisions were significantly reduced between 2016 and 2020 at shelters treated with the Feather Friendly markers even though collisions increased at shelters that remained untreated. For the 2020 analysis, there were significantly fewer collisions at treated than untreated shelters. Relative to a baseline study in 2016, we estimated that treating half of Stillwater's bus shelters resulted in a 64% reduction in total annual bird collisions. Together, these analyses provide a rigorous field test of the effectiveness of this treatment option in reducing bird-window collisions. Our research provides a model for similar studies at both bus shelters and buildings to evaluate and compare products designed to reduce bird-window collisions, and therefore, contribute to reducing this major mortality source affecting bird populations.

鸟类与窗户碰撞是人为造成鸟类死亡的一个主要原因，针对这一问题有多种缓解和预防措施。尽管旨在减少碰撞的产品越来越多（例如，带有蚀刻图案或标记的玻璃以及粘贴在现有玻璃上的薄膜），但很少有重复的实地测试来评估这些产品安装在玻璃上后的有效性。我们进行了一项实地研究，以评估一种商业销售产品（羽毛友好型标记）在美国俄克拉荷马州斯蒂尔沃特市玻璃墙公交候车亭减少鸟类与窗户碰撞方面的有效性。这项研究包括一个前后对照影响（BACI）分析，比较了18个公交候车亭在预处理期（2016年）和后处理期（2020年）的碰撞数量，以及在2020年对18个处理过的候车亭和18个未处理的候车亭进行的比较分析。对于BACI分析，尽管未处理的候车亭碰撞数量增加，但在使用羽毛友好型标记处理过的候车亭中，2016年至2020年期间碰撞数量显著减少。对于2020年的分析，处理过的候车亭的碰撞数量明显少于未处理的候车亭。相对于2016年的基线研究，我们估计对斯蒂尔沃特市一半的公交候车亭进行处理可使每年鸟类碰撞总数减少64%。总之，这些分析为这种减少鸟类与窗户碰撞的处理选项的有效性提供了严格的实地测试。我们的研究为公交候车亭和建筑物的类似研究提供了一个模型，以评估和比较旨在减少鸟类与窗户碰撞的产品，从而有助于减少这一影响鸟类种群的主要死亡来源。
