Species of the Week: Big Brown Bat

Photo by Adam Kalab

This week our featured #SpeciesOfTheWeek is the Big Brown Bat (Eptesicus fuscus). These nocturnal insectivores use echolocation to feed on things like moths, caddisflies, beetles, and flies. The Big Brown Bat is the most common bat species in Canada and, with a wingspan of up to 40cm, one of the largest. They range from southern Canada to central America and are highly adapted to living in cities where they roost in cavities, buildings and under the bark of trees. Although this species is not threatened, it is still under pressure from human activities such as pesticide use which kills their food source, and from a fungal disease called white-nose syndrome. During the winter, the Big Brown Bat hibernates inside houses, barns, caves, tree cavities or rock crevices; often these sites are located less than 80 km from their summer roosts. This particular bat was sighted at the staff house at Murphys Point. Have you spotted any bats flying around the campgrounds in the evening here at the park?
