COSEWIC Status Reports

COSEWIC Assessment and Status Report on the Little Brown Myotis Myotis lucifugus Northern Myotis Myotis septentrionalis Tri-colored Bat Perimyotis subflavus in Canada

All three bat species are small (average 7.4 g), brown-pelaged, insectivorous species of the Family Vespertilionidae. Little Brown Myotis (Myotis lucifugus) likely is the most common bat species in Canada and the most familiar of the three species to the public because they often use buildings as day-roosts and forage in areas where they are visible (e.g., over lakes, aound streetlights, etc.). Northern Myotis (M. septentrionalis) are common in forests and Tri-colored Bat (Perimyotis subflavus) is found in variety of habitats, but is rarer than the other two. Public concern over zoonotic diseases (i.e., rabies, histoplasmosis), noise, and hygiene has resulted in periodic extermination of maternity colonies and/or elimination of their roosts. Bats are predators of insects, some of which are considered pests in the agriculture and forestry sectors, and provide an important ecological service in this regard.
