There are 19 sepcies of bat in Canada and the little brown bat is the most widespread with 50% of the global population located in Canada. They can be found in every province except Nunavut. They hibernate during the colder months but emerge in the spring when it warms up. Bats have gotten a bad rap especially during the past several years but my eyes were opened after listening to a fascinating JRE podcast with guest Dr. Merlin Tuttle, a bat expert and scientist whose mission now is to inspire bat conservation worldwide. Bats and bees are very important for pollination. Little brown bats can eat half their body weight in mosquitos a night.
