Wild Canada: A Field Guide to Our Remarkable Wildlife, Birds, and Ecosystems

From the sprawling boreal forests of Northern Ontario to coastal wetlands and suburban backyards, Canada’s biodiversity is as diverse as the vast landscapes it inhabits. Whether you are an avid backcountry camper, a backyard birdwatcher, or simply curious about the creatures sharing our green spaces, understanding our local wildlife enriches our connection to the outdoors.

Here is a comprehensive guide to ten essential aspects of Canadian wildlife, including how to spot them, how they shape their environments, and how we can peacefully coexist with them.

1. Coyotes in Canada (Canis latrans)

Coyotes have proven to be among the most adaptable mammals in North America. Historically restricted to the open prairies, coyotes expanded their range eastward throughout the 20th century as forests were cleared and larger apex predators declined.

The Eastern Coyote

In Eastern Canada, including Ontario, Quebec, and the Maritimes, coyotes are noticeably larger than their western counterparts. Genetic testing reveals that Eastern coyotes carry genomic traces of both grey wolves and domestic dogs—a hybrid heritage resulting in what is colloquially called the “coywolf.” Weighing between 14 and 23 kg (30 to 50 lbs), they possess broader jaws and thicker coats.

Coexisting in Urban and Suburban Spaces

Coyotes are naturally timid, but human food sources (such as overflowing green bins, outdoor pet food, and unleashed small pets) can habituate them to suburban neighbourhoods.

• Never feed coyotes: Intentional feeding eliminates their natural fear of humans.
• Practice hazing: If a coyote approaches you, make yourself look large, wave your arms, and make loud noises (e.g., clapping, shouting, or using a whistle).
• Keep pets on a leash: Small dogs and outdoor cats are particularly vulnerable at dawn and dusk.

2. Black Bears (Ursus americanus)

The American black bear is found across every Canadian province and territory except Prince Edward Island. Despite their name, black bears in Western Canada can range in colour from jet black to cinnamon brown, blonde, or even the rare white Kermode (“Spirit”) bear of coastal British Columbia.

Autumn Hyperphagia

During late summer and autumn, black bears enter a phase called hyperphagia—a period of intense eating where they consume up to 20,000 calories a day to build fat reserves for winter hibernation. During this time, they forage heavily on wild blueberries, raspberries, acorns, and beech nuts.

Bear Safety Basics

Black bears are generally elusive and prefer to avoid human contact. When encountering a black bear:

1. Remain calm: Do not run, as running can trigger a chase response.
2. Back away slowly: Speak in a calm, firm voice while keeping your eye on the bear without staring aggressively.
3. Secure attractants: When camping, use bear-resistant canisters or hang food bags at least 4 metres (13 feet) off the ground and 2 metres (6.5 feet) out from a tree trunk.

3. Wolves (Canis lupus & Canis lycaon)

Wolves hold a vital position at the top of the food chain, maintaining healthy ecosystems by regulating ungulate (deer, moose, elk) populations and preventing overgrazing.

Grey Wolves vs. Eastern Wolves

Canada is home to two distinct wolf species:

• Grey Wolf (Canis lupus): Found across northern boreal forests, the tundra, and Western Canada. They live in tightly knit packs of 4 to 12 animals led by a dominant breeding pair.
• Eastern Wolf (Canis lycaon): Smaller than the grey wolf, this threatened species primarily inhabits Central Ontario and Western Quebec, with Algonquin Provincial Park serving as a critical refuge.

Ecosystem Impact: By altering the browsing habits of deer and moose, wolves indirectly protect young saplings and streamside vegetation, which in turn supports songbirds, aquatic life, and beaver populations—a classic example of a trophic cascade.

4. Moose (Alces alces)

The moose is the largest member of the deer family (Cervidae), standing up to 2 metres tall at the shoulder. Mature bulls can weigh over 600 kg and sport palmate antlers spanning up to 1.5 metres across.

Wetland Foraging and Diets

Moose require massive amounts of vegetation—around 20 to 30 kg per day. In spring and summer, they wade into shallow lakes, bogs, and river bays to feed on aquatic plants like pondweed and water lilies, which provide sodium essential for their diet.

Current Challenges

• Winter Ticks: Climate change has led to milder winters, enabling populations of winter ticks (Dermacentor albipictus) to surge. A single moose can host tens of thousands of ticks, leading to severe anemia, hair loss (“ghost moose”), and high calf mortality.
• Road Safety: Moose are dark-coloured and tall, making them difficult to spot at night on northern highways. Scan road shoulders carefully when driving through rural stretches.

5. Beavers (Castor canadensis)

Beyond its role as Canada’s official national symbol, the North American beaver is a keystone species and nature’s premier ecosystem engineer.

How Beavers Shape Landscapes

By felling trees (using iron-fortified orange teeth that grow continuously) and constructing dams across streams, beavers create slow-moving ponds and wetlands. These artificial impoundments:

• Filter pollutants and trap sediments, improving downstream water quality.
• Create vital habitat for waterfowl, amphibians, fish, and aquatic plants.
• Recharge local aquifers and mitigate summer droughts.

Adaptations

Beavers possess broad, flat tails used for propulsion, steering, and slapping the water surface as an alarm signal to family members. Transparent third eyelids (nictitating membranes) act as built-in goggles while swimming underwater.

6. Wild Turkeys (Meleagris gallopavo)

The return of the Wild Turkey is one of Canada’s greatest wildlife conservation success stories.

Extirpation and Reintroduction

By the early 1900s, overhunting and habitat loss had completely wiped out native wild turkey populations in Ontario and much of Eastern Canada. In the mid-1980s, wildlife biologists initiated a trap-and-relocation program, swapping Canadian otters for wild-caught turkeys from the United States.

The reintroduction succeeded beyond expectations. Today, robust populations thrive across Southern and Central Ontario, Quebec, and parts of Western Canada, adapting well to a mixture of hardwood forests, agricultural fields, and brushlands.

7. Snapping Turtles (Chelydra serpentina)

The Common Snapping Turtle is Ontario’s largest freshwater turtle, easily recognized by its heavy, saw-toothed tail, hook-like beak, and prehistoric appearance.

Life History and Conservation Status

Snapping turtles have existed virtually unchanged for millions of years, but they face modern threats that put their numbers at risk:

• Late Maturity: Snapping turtles do not reach reproductive maturity until they are 15 to 20 years old.
• Low Egg Survival: Nest predation by raccoons, skunks, and foxes accounts for high mortality rates.
• Road Hazards: During nesting season (late May through June), females trek overland to find gravelly soil or roadside shoulders to lay eggs.

Helping Turtles Cross the Road: If safe to do so, assist a turtle in the direction it is heading. For snapping turtles, use a shovel or push broom behind them, or grip the back half of the shell near the hind legs (never pick a turtle up by its tail, as this injures its spine).

8. Invasive Species Threatening Canadian Biodiversity

Non-native invasive species represent one of the primary drivers of habitat loss and native species decline across Canadian ecosystems.

9. Birds of Ontario

Ontario’s varied geography—spanning Carolinian forests in the south, mixed hardwoods, boreal coniferous belts, and subarctic tundra along Hudson Bay—provides habitat for over 400 bird species throughout the year.

Common Ontario Bird Habitats & Highlights
├── Lakes & Rivers: Common Loon, Osprey, Great Blue Heron
├── Boreal Forest: Black-capped Chickadee, Boreal Chickadee, Gray Jay, Evening Grosbeak
├── Deciduous Woodlands: Northern Cardinal, Blue Jay, Pileated Woodpecker, Wood Thrush
└── Migratory Corridors: Spring Warblers, Baltimore Oriole, Scarlet Tanager

Iconic Resident and Migratory Species

• Common Loon (Gavia immer): The iconic symbol of northern lakes, known for its eerie, wailing call and diving capabilities.
• Black-capped Chickadee (Poecile atricapillus): A hardy year-round resident famous for its friendly curiosity and distinct “fee-bee” spring whistle.
• Spring Migrant Warblers: Millions of songbirds pass through southern birding hotspots—such as Point Pelee National Park, Long Point, and Prince Edward Point—each May on their journey north from Central and South America.

10. Pollinators and Native Bees

While managed European honeybees often dominate headlines, Canada is home to over 800 species of native bees. Unlike honeybees, the vast majority of native bees are solitary, non-swarming, and rarely sting.

Essential Native Pollinators

• Bumble Bees (Bombus spp.): Capable of “buzz pollination” (vibrating flowers to release tightly held pollen), essential for native plants and agricultural crops like tomatoes and blueberries. The Rusty-patched Bumble Bee (Bombus affinis) is now critically endangered in Canada.
• Mason Bees (Osmia spp.): Exceptional spring pollinators that nest in hollow stems or wood cavities.
• Sweat Bees (Halictidae family): Small, often metallic-green or bronze bees that forage on summer wildflowers.

How to Support Native Pollinators in Your Backyard

1. Plant Native Flowers: Focus on native perennials like Wild Bergamot, Black-eyed Susan, Milkweed, Goldenrod, and New England Aster to provide bloom coverage from May through October.
2. Leave the Leaves: Many queen bumble bees and solitary species overwinter in leaf litter or hollow plant stems. Avoid cutting back garden stalks until spring temperatures consistently exceed 10°C.
3. Eliminate Cosmetic Pesticides: Avoid neonicotinoid insecticides and systemic lawn chemicals.
