6 Types of Bats Found In Manitoba! (ID GUIDE)
How can anyone in Manitoba think that bats are scary?
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. 🙂
Did you know there are 6 kinds of bats in Manitoba?
It’s hard to believe the diversity and amount of species that can be found in Manitoba! But, unfortunately, when you see a bat, it’s typically pretty difficult to determine which kind of bat it is. These nocturnal creatures fly incredibly fast and are only active at night.
#1. Big Brown Bat
- Eptesicus fuscus
Identifying Characteristics:
- Larger-sized bat with around a 30.48 centimeters wingspan.
- Brown fur with black ears, wings, and feet. Wings are hairless.
Big Brown Bats are widespread all over Manitoba.
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 Manitoba even use bat boxes to attract Big Brown Bats to their property!
Though rabies is common in all bats, research has shown the disease is rarer in this species.
The reason for this fact is that many Big Brown Bats have immunity to rabies. Interestingly, researchers discovered that these rabies antibodies get passed down from generation to generation!
#2. Hoary Bat
- Lasiurus cinereus
Identifying Characteristics:
- Brown hair with grayish-white tips. Wings and belly are brown and hairless, with a wingspan of approximately 39.37 centimeters.
- Males are almost double the size of females.
You’ll typically find Hoary Bats roosting on trees in woodland forests. But occasionally, they will go into caves to stay with other bats.

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 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 being a tree as they seek a place to rest. As you can imagine, these bats meet a horrible death.
#3. Silver-haired Bat
- Lasionycteris noctivagans
Identifying Characteristics:
- Medium-sized bat, flathead, and the upper part of the tail are covered in thick fur.
- Mostly black all over with white tips on hairs, with a wingspan that is approximately 29.21 centimeters.
The Silver-haired Bat is known to fly more slowly than other bats in Manitoba.
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.
Unfortunately, rabies occurs more often in this species when compared to other bats.
#4. Little Brown Bat
- Myotis lucifugus
Identifying Characteristics:
- Glossy brown fur on the body. Wings are hairless and black with a wingspan that is approximately 22.86 to 27.94 centimeters.
- Despite its name, it has no connection to the Big Brown Bat.
The Little Brown Bat is common and lives throughout Manitoba.
Look for them in sheltered places such as human structures, woodpiles, tree hollows, and occasionally caves.

Little Brown Bats will commonly use a bat house for roosting. Many people put up bat houses to attract them to their property to control pests like mosquitos or insects that harm crops.
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
Identifying Characteristics:
- Medium-sized tree bat with thick, long fur. Ears are short and round. Wings are long, pointed, and have a wingspan of approximately 33.2 centimeters.
- 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 Manitoba.
I love their red fur, which I think makes them look cute!

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 will 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
Identifying Characteristics:
- Fur and wing membranes are tan, with black ears and black wings: long tail and a wingspan up to 25.4 centimeters.
- Look for their long pointed ears.
- Also called the Northern Myotis.
Northern Long-eared Bats are found in Manitoba 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 together 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 while 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!
