Bird-window collisions occur across North America and are estimated to kill hundreds of millions of birds annually. Previous studies show that collisions occur non-randomly and can be influenced by building characteristics, time-of-year, and species-specific physiology and behaviour. Much of the available research is based in northeastern North America, though different species and habitats in the West may be affected differently. We collected strike data from 2 buildings in Victoria, British Columbia, from June to October 2018. We found that window width was positively related to the probability of a strike occurring, whereas vegetation distance to window, window aspect, and the building at which it occurred did not predict strike probability. A substantial increase in strikes occurred in September and October, which coincides with peak migration on Vancouver Island, and suggests that migration influences collision risk to bird species.
