MAMMALS OF MUSKOKA: AN OVERVIEW
The forests, wetlands and lakes of Muskoka support a rich variety of wildlife. Located along the rugged Canadian Shield and within a transition zone known as
The Land Between, Muskoka contains a mix of northern boreal and southern hardwood ecosystems. This diversity of habitats supports about 50 species of mammals, from large animals such as moose and bears to tiny bats and shrews. Together, these species form a complex ecological network that keeps the region’s natural systems healthy. Whether glimpsed crossing a quiet road at dusk or discovered through tracks in fresh snow, Muskoka’s mammals are an essential and fascinating part of our region.
The Land Between charity is a grassroots and collaborative non-government organization, that works closely with many local community groups and individual landowners who have important knowledge when it comes to land, wildlife and history. They host Talking Circles to uncover issues related to wolves, coyotes, beavers and wetlands. Talking Circles are held throughout the region, including Muskoka.
Have you noticed more or fewer beavers in your area? Are canids around and increasing? Have wetlands been dry or are they being lost? These events are free and open to the public. Refreshments will be served. Join in to share observations, or simply drop by to explore their fish and wildlife research results from across the region.
On a related note, Aspen Valley Wildlife Sanctuary, located in Rosseau, is a leader in wildlife rehabilitation. Their primary goal is to rehabilitate injured and orphaned wildlife, and release them back into the wild for a second chance. It is also home to more than 40 permanent wildlife residents, whose stories are shared during guided tours, which can be scheduled year-round.
Large Mammals
Black Bears
One of the most iconic animals of Muskoka is the American black bear. Bears are common throughout the region and are usually shy and avoid people. They spend much of their time foraging for berries, insects, and vegetation, though they are also opportunistic feeders. In late fall, bears enter a winter den where they remain dormant until spring. Because bears are attracted to easy food sources, residents and cottage owners are encouraged to secure garbage and avoid feeding wildlife.
Moose
The moose is the largest mammal in Ontario and a symbol of northern wilderness. Moose prefer wetlands, lakeshores and young forests where they browse on aquatic plants, twigs and leaves. Their long legs and large hooves help them move easily through deep snow and marshy terrain. Although sightings are exciting, moose can be unpredictable, particularly during the fall breeding season.
Deer
White-tailed deer are common in Muskoka’s forests and fields. They are most active at dawn and dusk and often move through woodland edges or near lakes. Deer play an important ecological role as browsers but are also prey for large predators.
Wolves and Coyotes
Predators such as wolves and coyotes help maintain ecological balance by controlling deer and other prey populations. The eastern wolf occurs in the broader region, while coyotes are widespread and adaptable. These animals are rarely seen but may be heard howling at night.
Cougars (Rare Sightings)
Reports of cougars occasionally surface in Ontario. While confirmed populations are uncertain, wildlife experts acknowledge that transient individuals may move through remote areas of the province.

Medium-Sized Mammals
Many mammals in Muskoka fall into a middle size range and are often called furbearers because their dense fur historically made them valuable in the fur trade.
Beaver
The beaver is one of Canada’s most influential animals. Beavers build dams and lodges that create wetlands, which in turn provide habitat for fish, amphibians, birds and other mammals. Because of this ability to reshape landscapes, they are considered a keystone species.
River Otters
North American river otters are playful aquatic mammals often seen sliding along snowy banks or swimming in lakes and rivers. They are skilled hunters that feed mainly on fish but also eat frogs and small mammals.
Mink and Muskrat
Wetlands also support smaller aquatic mammals such as mink and muskrats. Mink are sleek predators related to weasels, while muskrats are herbivores that build dome-shaped lodges in marshes.
Foxes and Raccoons
The red fox is a familiar sight in Muskoka’s fields and forests. Known for its intelligence and adaptability, it hunts small mammals and birds. Raccoons are another common species. Highly adaptable, they thrive near lakes, forests and even cottage areas.

Small Forest Mammals
A wide variety of smaller mammals inhabit Muskoka’s forests. Common species include:
- Porcupines, which feed on tree bark and needles
- Snowshoe hares, whose large feet help them travel over deep snow
- Martens and fishers, agile forest predators
- Squirrels and chipmunks, which store nuts and seeds
- Skunks, weasels, voles and mice
Bats
Bats are the only mammals capable of true flight and are important insect predators. In Ontario, several species occur, including the little brown bat, which can consume thousands of insects in a single night. During winter, bats hibernate in caves, mines or other protected spaces where temperatures remain stable. Unfortunately, many populations have declined due to white-nose syndrome, a fungal disease that disrupts hibernation. Despite their reputation in folklore, bats are harmless to humans and provide major ecological benefits by controlling mosquitoes and agricultural pests.
Mammals in Winter
Winter dramatically changes how mammals behave in Muskoka. Different species survive the season in different ways:
- Hibernation: Bats and some small mammals enter deep torpor to conserve energy.
- Dormancy: Black bears remain inactive in dens through winter.
- Adaptation: Animals such as deer and foxes remain active, growing thicker fur and conserving energy.
Living With Muskoka’s Wildlife
Because Muskoka includes extensive cottage and recreational areas, people and wildlife frequently share the same landscapes. Simple actions can reduce conflicts and protect both animals and people:
- Secure garbage and compost
- Avoid feeding wildlife
- Keep pets supervised outdoors
- Protect natural habitats such as wetlands and forests
