Bats

Little Brown Bat (Myotis lucifugus)

• Widespread in North America; however, one of the hardest hit species from white-nose syndrome and is now rare in parts of eastern Canada and the US.

• Form large maternity groups (usually >100 individuals) and often roosts in anthropogenic structures.

Northern Long-eared Myotis (Myotis septentrionalis)

• Primarily found in eastern North America; however, it inhabits forests as far west as BC.

• Also hard hit by white-nose syndrome in eastern North America.

• Form small maternity groups or roost solitary typically in trees, but can make use of anthropogenic structures.

• Identifiable by a long and pointed tragus (prominence on inner ear).

Yuma Myotis (Myotis yumanensis)

• Found in western North America

• Form large maternity groups (usually >100 individuals) and often roosts in anthropogenic structures.

• Similar appearance to little brown bats, but smaller and have higher frequency echolocation calls (>45kHz)

Western Small-footed Bat (Myotis ciliolabrum)

• Found in western North America, primarily in the US, but also southern portions of BC, AB, and SK.

• Form small maternity groups or roost solitary typically in rock crevices.

• Characterized by pale, yellow fur and small feet (they're typically just toes!) 

Long-eared Myotis (Myotis evotis)

• Found in western North America. 

• Form small maternity groups or roost solitary typically in rock crevices and trees, but can use anthropogenic structures.

• Characterized by very long ears.

Big Brown Bat (Eptesicus fuscus)

• Widespread in North America.

• Not as hard hit by white-nose syndrome, but has still suffered population declines in the east. 

• Form either small or large maternity groups and often roosts in anthropogenic structures.

• Larger than Myotis species and characterized by a wide, short snout.

Silver-haired Bat (Lasionycteris noctivagans)

• Widespread in North America.

• Usually migrate to the US in fall, but some individuals over-winter in Canada.

• High mortality rates at wind farms due to their migratory nature.

• Form small maternity groups and typically roost in trees, but can also use anthropogenic structures.

Hoary Bat (Lasiurus cinereus)

• Most widespread species in the Americas and can also be found in Hawaii and the Caribbean.

• Migrate long distances.

• Suffering substantial population declines due to high mortality rates at wind farms.

• Roost solitary in trees.

• Largest bat in Canada.

Red Bat (Lasiurus borealis)

• Primarily occurs in Eastern North America, but can be found as far west as BC.

• Typically migrate in fall, but some individuals over-winter in the northern parts of their range.

• Experiences high mortality at wind farms.

• Roost solitary in trees. 

• Can hibernate in leaf litter on the ground.
