9 Types of Bats In Alberta! (ID GUIDE)

How can anyone in Alberta think that bats are scary?

Types of bats in Alberta

Despite what you see in the movies, these fascinating flying mammals wouldn’t hurt a fly! Well, technically, they would hurt a fly, or a mosquito, or a moth. But other than that, bats are harmless. 🙂

It’s hard to believe the diversity and amount of bat species that can be found in Alberta! But, unfortunately, when you see a bat, it’s typically pretty difficult to determine which kind it is. These nocturnal creatures fly incredibly fast and are only active at night.

9 kinds of bats in Alberta:


#1. Big Brown Bat

  • Eptesicus fuscus

Types of bats in Alberta

  • It is a larger bat with around a 12-inch (30 cm) wingspan.
  • Brown fur with black ears, wings, and feet. Wings are hairless.

Big Brown Bats are among the most common bats in Alberta.

If you look, you’ll find these bats inside caves, tunnels, or other human structures.

This nocturnal bat primarily eats insects, especially ones that fly at night. However, their preference is to eat beetles.

The Cucumber Beetle is their favorite, which benefits farmers because these insects are terrible pests for agriculture. Many farmers in Alberta even use bat boxes to attract Big Brown Bats to their property!

Interestingly, many Big Brown Bats have immunity to rabies. Researchers discovered that these rabies antibodies get passed down from generation to generation!

#2. Hoary Bat

  • Lasiurus cinereus

  • Brown hair with grayish-white tips. Wings and belly are brown and hairless, with a wingspan of approximately 15.5 inches (39 cm).
  • Males are almost double the size of females.

You’ll typically find Hoary Bats in Alberta roosting on trees in woodland forests. They are solitary bats that roost in open foliage. They do form “flocks” when migrating south in late summer, but they don’t hang out with other bats normally.

This species prefers to hunt for prey while flying over wide-open areas or lakes. Hoary Bats hunt alone and enjoy eating moths. They’re known to travel up to 24 miles (39 km) in a single night to gather food!

Though the Hoary Bat is not endangered, it does suffer a loss in numbers because of wind turbines. Hoarys migrate each year back and forth from North America to Central America, and it’s thought that they confuse the wind turbine with a tree as they seek a place to rest.


#3. Silver-haired Bat

  • Medium-sized with a flathead. The upper part of the tail is covered in thick fur.
  • Mostly black all over with white tips on hairs, with a wingspan of approximately 11.5 inches (29 cm).

This species is known to fly more slowly than other bats in Alberta.

Look for Silver-haired Bats in forests inside tree cavities or bark crevices. They’ve also been known to seek shelter in outbuildings.

Silver-haired Bats hunt for soft-bodied insects, such as moths. Interestingly, they also eat a lot of spiders. They accomplish this feat by foraging low to the ground to find food, unlike many other bats.


#4. Little Brown Bat

  • Myotis lucifugus

Types of bats in Alberta

  • Glossy brown fur on the body. Wings are hairless and black, with a wingspan of approximately 10 inches (25 cm).
  • Despite its name, it has no connection to the Big Brown Bat.

Look for the Little Brown Bat roosting in Alberta in sheltered places such as human structures, woodpiles, tree hollows, and occasionally caves.

You can even attract Little Brown Bats to your yard! Many people put up bat houses to attract them to their property to control pests like mosquitos or insects that harm crops.

Distribution of all little brown bat subspecies: M. l. lucifugus (red), M. l. pernox (green), M. l. alascensis (blue), M. l. carissima (yellow), M. l. relictus (gray)

Little Brown Bats only have a few natural predators, like owls or raccoons. Unfortunately, most of their mortality is caused by parasites or White-nose syndrome.

White-nose syndrome is a fungal disease that grows around the bats’ mouths, ears, and wings. This illness is spread during hibernation and is responsible for the loss of over one million Little Brown Bats between 2006 and 2011. As of 2018, the Little Brown Bat is an endangered species.


#5. Eastern Red Bat

  • Lasiurus borealis

  • Medium-sized tree bat with thick, long fur. Ears are short and round. Wings are long, pointed, and have a wingspan of approximately 13 inches (33 cm).
  • Males have distinctive rusty red-colored fur, and females have more of a soft shade of red.
  • Both have white patches of fur on their shoulder.

Eastern Red Bats like to roost in trees in Alberta.

These bats are relatively fast flyers with good maneuverability. They are insectivorous, which means they prey primarily on different insects, with their favorite being moths.

Unlike most bats that only produce one offspring, Eastern Red Bats have three pups in a litter.

Eastern Red Bats have few predators. However, sometimes hawks, aggressive Blue Jays, and crows attack them. This bat is also killed by flying into cars or wind turbines. Unfortunately, this species has the second-highest mortality rate from wind turbines.


#6. Northern Long-eared Bat

  • Myotis septentrionalis
Myotis septentrionalis. (2023, October 9). In Wikipedia.
  • Fur and wing membranes are tan, with black ears and black wings: long tail and a wingspan up to 10 inches (25 cm).
  • Look for their long, pointed ears.
  • Also called the Northern Myotis.

Northern Long-eared Bats are found in Alberta in forested habitats with spruce and pine trees. They typically roost in trees during the summer and switch to a new roost every other day. In the fall, these bats migrate to caves to hibernate with other species of bats.

Northern Long-eared Bats have incredibly accurate echolocation calls, which helps them navigate their dense forest environments.

Unlike most bats, Northern Long-eared Bats capture their prey by plucking them from a surface rather than catching them in flight. They eat insects, with moths being their favorite.

Sadly, the Northern Long-eared Bat has been threatened by White-nose syndrome, a fungal disease that kills many bats. This disease has decreased their population by 99%. Click play to learn more below!

  • Smaller bat, with yellowish-brown fur and sometimes white underparts.
  • The muzzle, chin, and ears are black. Ears are also long. Their wingspan is approximately 9 inches (23 cm).
  • Feet are tiny, just as their name suggests.

The Western Small-footed Bat is found in semi-arid habitats in Alberta.

Though this bat is a slower flyer, it can maneuver well. The Western Small-footed Bat tends to feed close to the water, searching for insects like beetles, moths, and flies.

Western Small-footed Bat females roost in groups, and males roost alone, but both hibernate in winter in solitude.


#8. Long-legged Bat

  • Myotis Volans
Long-legged myotis. (2023, October 25). In Wikipedia.
  • Fur color can vary from light or dark brown to reddish-brown. Tips of their can actually touch their nostrils. Wingspan is approximately 9 inches (23 cm).
  • Unlike other bats, they have fur on the underside of their wings from elbows to knees.
  • They got their name from having a longer tibia bone when compared to other bats.

The Long-legged Bat has unique feet that allow them to hang upside down for an extended time without wasting energy. This feat is accomplished by locking their toes in place. In addition, special cavities in their head prevent blood from going to their brain.

Long-legged Bat Range Map

These bats prefer to roost in the barks of trees and crevices in rocks, caves, and buildings. They like to spend time in higher elevations in the summer, and then in the winter, they will come down and live and hibernate in caves and mines.

Like other bats in Alberta, they primarily eat mainly moths using echolocation. However, the Long-legged Bat differs because they get a head start over other bats! They do this by leaving their roost early, foraging before sunset, and then eating throughout the entire night.

Check out this video to see how the Long-legged Bat uses echolocation to catch moths!

#9. Long-eared Myotis

  • Myotis evotis
Long-eared myotis. (2023, August 18). In Wikipedia.
  • Their face and ears are black. The fur on their back ranges from yellowish to dark brown. The wingspan is approximately 10 inches (25 cm).
  • Long dark ears, which is how they got their name.

This bat is found in woodlands, shrublands, grasslands, and agricultural areas. This species leaves its roosts in rocky regions, dead trees, caverns, and buildings to forage insects in dense vegetation.

Long-eared Myotis Range Map

The Long-eared Myotis is active longer at night than most other bats, hunting closer to the ground as the night gets cooler.

Unlike other bats in Alberta, the Long-eared Myotis often turns off echolocation when hunting. Instead, their long ears help them HEAR prey the old-fashioned way. Click play below to see an example!

  1. Please check http://www.albertabats.ca for background information on Alberta’s bats! We actually only have 9 species. We would love to find California Myotis and Yuma Myotis but they have never been captured or acoustically detected in Alberta. You also have some mis-labeled photos. Long-legged Myotis don’t have the fancy nose. They look a lot like a Little Brown Myotis. They are not at all well-known, so it isn’t surprising that you couldn’t find many photos. Only a few people have studied them and when we net for bats, they are rarely captured. The Long-eared Myotis depicted on the left (roosting) is likely a Townsend’s Big-eared Bat (although there are a few other Big-eared bats that also look like that fellow). Your photos of Northern Myotis aren’t quite right either – not sure exactly who that is but it doesn’t look like septentrionalis.

    I didn’t read through all of your species accounts, but there are a few things that are not right. Hoary bats never roost in caves. They are solitary bats that roost in open foliage. Recent work during the winter has found them using leaf piles and torpor (which is a new thing we didn’t know). They do form “flocks” when migrating south in late summer/fall (this is when mating happens) but they don’t hang out with other bats normally.

    And the rates of rabies in bats does vary with species but it isn’t at all common. Less than 0.5% of the free-flying population will contract rabies. The rates are higher in bats that are submitted for testing (up to about 10% of bats submitted test positive) but this is a biased sample. People send in bats that are on the ground or acting strangely. Your typical bat rarely will be found with rabies and they don’t “carry” the disease. It will kill them (and rather quickly). But the rule is that if you have bare-skin contact with a bat – seek immediate medical advice & a post exposure rabies series (which are just small shots in the arm). Rabies is fatal and once symptoms appear, they can’t help you. But the post exposure series is effective at preventing the disease.

    There are a few other things in your accounts that aren’t quite right. Please feel free to look at our guidebooks @albertabats for some good information. It is great that you are posting and learning about bats! So many people have questions. #BatsNeedFriends #EducationIsPower

    1. Susan,

      First, thank you SO MUCH for the in-depth response. That is such great information. When we wrote some articles about bats, we found it challenging to find information. This is great stuff. I have made a reminder to go and update our articles based on this new information. Your website looks very informative too. 🙂
