Summer movements of a radio-tagged Hoary Bat (Lasiurus cinereus) captured in southwestern Ontario

Derek Morningstar, Al Sandilands


Hoary Bat (Lasiurus cinereus) is a migratory species known to travel long distances during migration. Little is known about its movement patterns during other periods. An adult male Hoary Bat that we radio-tagged in southwestern Ontario in summer was tracked using the Motus Wildlife Tracking System. It travelled a minimum of 827 km in a circular route over a 2-week period and was last recorded 46 km from the original capture site. Hoary Bat is highly vulnerable to being killed at wind turbines and its propensity to travel great distances during summer and migration may exacerbate the impacts of wind farms.
