Final Research Report : Buchanan Birds Harter, Linda Clarke


The human-wildlife conflict of bird-window collisions accounts for an estimated 25 million annual bird deaths in Canada. This research report sets out to find out how this statistic is reflected at the University of British Columbia (UBC), in their Faculty of Arts Buchanan buildings. Evidence of bird-window collisions including feather smears, feather piles and carcasses, were searched for 4 days a week over a period of 64 days. At least 33 bird-window collisions occurred during this time period. Carcass persistence and searcher efficiency trials were conducted to help lower study bias. This paper examines why birds collide with windows, factors that increase collision rates, report results of the study, compares last years’ Buchanan study data of 49 collisions to this year’s data of 33 collisions to discuss varying factors, and find the facades that have the highest collision rates so that mitigation strategies can be applied. The effect of Feather Friendly © on façade 27 was investigated and found to be effective, decreasing bird window collisions by 90-100%. The recommended treatment is Feather Friendly © for façade 13 immediately and then 25 and 10 in the future. The results of this study can be used to lower the mortality rate of birds at the Buchanan buildings and hopefully shine a light on the urgency of UBC retrofitting their buildings to be more bird-friendly in design.
