Wildlife refers to animals, birds, insects, and other organisms that live and survive in their natural environments without being domesticated by humans. Wildlife can be found in forests, wetlands, grasslands, mountains, oceans, and even urban neighbourhoods. Common examples include raccoons, squirrels, skunks, rabbits, deer, foxes, and many species of birds.
Wild animals play an important role in maintaining healthy ecosystems. They help control insect populations, disperse seeds, pollinate plants, and support natural food chains. However, when wildlife enters residential or commercial properties, it can sometimes cause damage or create safety concerns. Understanding wildlife helps people appreciate nature while learning how to coexist responsibly with wild animals.
What Is the Definition of Wildlife?
Wildlife is the collective term for animals and other organisms that live independently of direct human domestication. These organisms obtain food, find shelter, reproduce and respond to environmental conditions as part of natural ecosystems.
The term most commonly refers to wild animals, including mammals, birds, reptiles, amphibians, fish and insects. Depending on the context, it can also include wild plants and other organisms that contribute to natural biodiversity.
For example, a raccoon searching for food in a woodland, a hawk flying above a field, a turtle living near a pond and a butterfly feeding on flowers are all examples of wildlife.
Wild animals do not necessarily have to live far away from people. A squirrel nesting in a tree beside a house remains wildlife because it has not been domesticated.
Similarly, an animal does not stop being wildlife simply because it enters a building or becomes accustomed to an urban environment. Its behaviour and ecological role are still connected to its natural biology.
To learn about animals that commonly live near people, explore our guide to what wildlife is and how wild animals live.
What Are the Main Types of Wildlife?
Wildlife includes an enormous variety of species. Scientists often group animals according to their biological characteristics, such as whether they have backbones, how they reproduce and how they regulate their body temperature.
The following categories cover some of the most familiar types of wildlife.
1. Mammals
Mammals are warm-blooded vertebrates that generally have hair or fur and feed their young with milk. Most give birth to live young, although a small number lay eggs.
Examples of mammals include:
Raccoons
Squirrels
Foxes
Deer
Bats
Rabbits
Skunks
Bears
Mammals occupy a wide range of habitats, from forests and grasslands to wetlands and cities. Some are active during the day, while others are mainly nocturnal.
In residential areas, raccoons and squirrels may use attics, sheds, chimneys or gaps beneath decks as shelter. Their presence can sometimes cause property damage, particularly when animals enter enclosed spaces or build nests inside structures.
Read our guides to what raccoons are and what squirrels are to learn more about two mammals frequently encountered around homes.
2. Birds
Birds are warm-blooded vertebrates with feathers, beaks and wings. Although most birds can fly, some species are flightless.
Common examples include:
Robins
Hawks
Owls
Ducks
Geese
Woodpeckers
Eagles
Pigeons
Birds contribute to ecosystems by spreading seeds, pollinating certain plants, eating insects and helping maintain food webs. Predatory birds also help regulate populations of smaller animals.
Birds use trees, shrubs, cliffs, wetlands and other structures for nesting and shelter. Some species also nest on buildings, ledges and roofs.
Bird nests and eggs may be protected by provincial or federal law. Before disturbing a nest or attempting to remove nesting material, check the applicable requirements. Ontario provides guidance in its official resource on removing bird nests or eggs.
3. Reptiles
Reptiles are generally cold-blooded vertebrates with scales or protective skin coverings. They rely on external sources of heat to regulate their body temperature.
Examples include:
Snakes
Turtles
Lizards
Crocodilians
Reptiles live in habitats such as forests, wetlands, grasslands, deserts and freshwater environments. Some species help control rodent and insect populations, while others serve as prey for larger animals.
Snakes sometimes enter garages, sheds or gardens while searching for shelter, prey or suitable temperatures. Their presence does not automatically mean that a property is unsafe or that an infestation exists.
If a snake appears around your home, keep a safe distance and avoid attempting to catch or handle it. Contact an appropriate local wildlife professional if it is inside a building or presents a genuine concern.
4. Amphibians
Amphibians include frogs, toads, salamanders and newts. Many amphibians depend on moist environments and have life cycles that involve water.
Frogs, for example, often lay eggs in ponds or other suitable aquatic habitats. Their young commonly develop through a tadpole stage before becoming adults.
Amphibians are important because they consume insects and provide food for other animals. Their sensitivity to environmental changes can also make them useful indicators of ecosystem health.
Pollution, wetland destruction, disease and changes in water conditions can threaten amphibian populations.
5. Fish and Aquatic Wildlife
Aquatic wildlife includes fish and many other organisms that live in freshwater or marine environments.
Examples include:
Salmon
Trout
Bass
Freshwater mussels
Crabs
Octopuses
Marine mammals
Aquatic organisms contribute to food webs, nutrient cycling and the health of water-based ecosystems. Freshwater wildlife depends on rivers, lakes, streams and wetlands. Marine wildlife relies on oceans, coastal habitats, reefs and other underwater environments.
Clean water, suitable breeding areas and healthy food supplies are essential for aquatic species to survive.
6. Insects and Other Invertebrates
Invertebrates are animals without backbones. This broad group includes insects, spiders, worms, snails and many aquatic organisms. Wild insects include bees, butterflies, beetles, dragonflies and many other species. They contribute to pollination, decomposition, soil health and food chains.
Not every insect or small animal found around a building is a pest. Many are beneficial and play important ecological roles. For example, pollinating insects help plants reproduce, while decomposers break down organic material and return nutrients to the soil.
Some species, however, can damage structures, stored food or gardens. Learning to distinguish beneficial wildlife from animals that require management helps homeowners make informed decisions.
Where Does Wildlife Live?
Wildlife can survive in almost every part of the world, provided that environmental conditions meet its basic needs. Each species requires an appropriate combination of food, water, shelter, space and breeding opportunities. A place that provides these resources is known as a habitat.
Forests and Woodlands
Forests provide trees, shrubs, fallen logs, leaf litter and other resources that support a wide range of animals. Birds nest in branches, squirrels use tree cavities, and mammals find food and shelter among vegetation. Fallen wood and decomposing leaves also support insects, fungi and other organisms.
Healthy forests contain many interconnected habitats. Removing vegetation or fragmenting woodland can reduce the resources available to wildlife.
Grasslands and Open Fields
Grasslands provide food and shelter for grazing mammals, rodents, insects and ground-nesting birds. The vegetation supports herbivores, which in turn provide food for predators. Many grassland species depend on particular plant communities and seasonal conditions.
When grasslands are converted into roads, buildings or intensively managed land, wildlife may lose important feeding and breeding areas.
Wetlands and Freshwater Habitats
Wetlands include marshes, swamps and other areas where water influences the soil and vegetation. These habitats provide breeding grounds for amphibians, feeding areas for birds and shelter for numerous aquatic organisms. They can also help filter water and reduce flooding.
Protecting wetlands supports biodiversity and preserves resources that many species need throughout their life cycles.
Urban and Suburban Areas
Wildlife also lives in towns and cities. Parks, gardens, mature trees, waterways and green spaces can provide food and shelter. Raccoons may search for food around rubbish bins. Squirrels may nest in trees or roof spaces. Birds may feed in gardens, while bats may use suitable roosting sites.
Urban wildlife often adapts its behaviour to human activity. Some animals become active at night because food and other resources are easier to access when people are less active.
However, an animal entering a home or commercial building can create a wildlife conflict. It may damage insulation, chew materials, leave droppings or create noise.
Our guide to how to get rid of wildlife animals explains why identifying the animal and understanding how it entered a property are important first steps.
Agricultural and Rural Landscapes
Farms, orchards, fields and rural properties support many species. Birds, insects, rodents and mammals may use crops, hedgerows, barns and nearby woodlands.
Some wildlife benefits agriculture by pollinating crops or eating insects that damage plants. Other species may feed on stored grain, damage crops or enter farm buildings.
Maintaining suitable habitat while managing attractants can help reduce unnecessary conflicts.
Humane Wildlife Removal
Wildlife can harm your residential or commercial property in many ways. Starting from damaging the structure of your house; wildlife can also harm you and your family members directly. To prevent and/or stop wild animals from causing problems, you need a professional wildlife removal service in Toronto & GTA.
Why Is Wildlife Important?
Wildlife supports ecological processes that benefit natural environments and human communities. Even species that people rarely notice can have an important role in keeping ecosystems functioning.
1. Maintaining Food Chains
Food chains describe how energy moves between organisms. Plants use sunlight to produce energy-rich material, herbivores eat plants, and predators feed on other animals.
Decomposers break down dead organisms and return nutrients to the environment. Wildlife forms part of these interconnected relationships. If one species declines significantly, other organisms that depend on it may also be affected.
Healthy ecosystems generally depend on a balance of species and resources rather than the dominance of a single animal.
2. Pollination and Plant Reproduction
Many plants depend on animals to transfer pollen between flowers. Bees, butterflies, moths, birds and some other animals contribute to pollination. This process allows many plants to produce seeds and, in some cases, fruit.
Wild pollinators support natural vegetation and contribute to agricultural production. Protecting flowering plants and suitable habitats can help maintain their populations.
3. Seed Dispersal
Some animals eat fruit and carry seeds away from the parent plant. Other animals move seeds on their fur or transport them while gathering food. This movement helps plants spread into new areas and supports the regeneration of forests and other habitats. When seed-dispersing animals disappear, the composition and recovery of plant communities can change.
4. Natural Pest Regulation
Birds, bats, spiders, amphibians and predatory insects consume a variety of other organisms. In suitable ecosystems, these relationships help regulate populations.
However, the presence of predators does not guarantee that a particular pest problem will disappear. The effectiveness of natural pest control depends on species, habitat, food availability and other conditions.
Where pests enter homes or commercial buildings, a proper inspection and a targeted management plan may still be necessary.
5. Soil Health and Nutrient Cycling
Wildlife contributes to the movement and recycling of nutrients. Earthworms and other soil organisms break down organic matter. Burrowing animals can change soil structure, while scavengers and decomposers help process dead organisms.
These activities support soil fertility and influence how water and nutrients move through ecosystems.
6. Supporting Biodiversity
Biodiversity refers to the variety of living organisms, including genetic diversity, species diversity and the ecosystems in which they live. A diverse ecosystem may be better able to withstand certain environmental disturbances because different organisms perform different roles.
Wildlife conservation helps protect these relationships and preserves the natural resources that communities depend on.
7. Educational, Cultural and Recreational Value
Wildlife offers opportunities for birdwatching, photography, nature walks and environmental education. Observing animals can help children and adults understand seasonal changes, food webs and the importance of habitat protection.
Wildlife also has cultural significance for many communities and contributes to the appeal of natural parks and outdoor recreation areas.
How Do Wild Animals Adapt to Their Environment?
Animals develop physical characteristics and behaviours that help them survive in particular environments. These adaptations may influence how they obtain food, avoid predators, find shelter and reproduce.
Physical Adaptations
Physical adaptations are features of an animal’s body that improve its ability to survive.
Examples include:
Thick fur that provides insulation in cold environments.
Webbed feet that help certain animals swim.
Sharp claws that assist with climbing or catching prey.
Camouflage that makes an animal harder to see.
Specialised beaks that help birds obtain different food sources.
These features develop over generations through evolutionary processes.
Behavioural Adaptations
Behavioural adaptations involve actions that help animals survive. Some animals are nocturnal and search for food at night. Others migrate when temperatures change or food becomes less available.
Certain mammals store food, while some species live in groups that provide protection or improve access to resources. Wild animals may also change their behaviour when their surroundings change. Urban animals can learn to use predictable food sources, although becoming accustomed to people can create risks for both wildlife and residents.
Seasonal Adaptations
Seasonal changes affect food supplies, temperatures, water availability and breeding opportunities. Some animals migrate to more suitable locations. Others become less active during cold weather, store energy or change their feeding patterns. These behaviours help wildlife cope with environmental conditions without requiring every species to respond in the same way.
What Is the Difference Between Wildlife and Domesticated Animals?
Wildlife and domesticated animals differ mainly in their relationship with humans and the processes through which their populations have developed.
Domesticated animals have been selectively bred over generations to live alongside people and fulfil particular roles. Examples include domestic dogs, cats, cattle and chickens.
Wild animals generally retain the behaviours and ecological requirements associated with their species in natural environments.
These categories are not always simple. A wild animal may become accustomed to people without becoming domesticated. Similarly, an escaped domestic animal does not automatically become a wild species.
Keeping wildlife as a pet can create welfare and legal concerns. Animals may require specialised diets, space and environmental conditions that a household cannot provide. Rules on wildlife possession also vary by species and location.
Common Wildlife Found Around Homes
Residential areas often provide food, shelter and access to water. These resources can attract wild animals, particularly when buildings contain accessible gaps or outdoor food sources.
Understanding the behaviour of common species helps homeowners recognise when an animal is simply passing through and when it may be using a structure as a den or nesting site.
Raccoons
Raccoons are adaptable mammals that can live in forests, wetlands and urban neighbourhoods. They are omnivores and may eat fruit, insects, small animals and human food waste.
Unsecured rubbish bins, pet food and accessible openings can attract them to properties. Raccoons may also seek shelter in attics, chimneys or other enclosed spaces.
Avoid approaching a raccoon that appears injured, disoriented or unusually aggressive. Keep children and pets away and seek appropriate professional advice when necessary.
Learn more in our article about the best way to get rid of raccoons.
Squirrels
Squirrels commonly live in trees and use cavities, nests and other sheltered locations for resting and raising young. They may enter roof spaces through damaged vents, gaps along rooflines or other openings. Once inside, they can disturb insulation and chew building materials.
If you hear repeated scratching or movement in an attic, do not immediately seal every opening. An animal may still be inside, and young may be present during the breeding season.
Our guide on how to get rid of squirrels in the attic covers this type of residential wildlife concern.
Skunks
Skunks are generally nocturnal mammals that search for insects, grubs and other food sources. They may shelter beneath decks, porches, sheds or other protected structures. Strong odours, digging and repeated activity near a sheltered opening may indicate that a skunk is using an area.
Do not block a suspected den without checking whether an animal is present. Keep your distance and avoid actions that could frighten or corner the animal. For more information, read our guide to what skunks are.
Birds
Birds may nest in trees, roof cavities, vents, ledges and other sheltered locations.Nesting activity can sometimes create noise or block ventilation openings. However, disturbing a nest may be restricted by law, depending on the species and circumstances.
Identify the bird and check applicable rules before removing a nest or installing exclusion materials.
Bats
Bats are nocturnal mammals that commonly feed on insects, although diets vary among species. Some use trees, caves or suitable building cavities as roosting sites.
A bat found inside a living space requires careful handling because direct contact can create a potential rabies exposure concern. Do not handle it with bare hands.
If a person or pet may have had contact with a bat, contact local public health or a veterinarian promptly for appropriate advice. If a bat is roosting in a building, seek qualified guidance before attempting exclusion, particularly when young may be present.
What Attracts Wildlife to Residential Properties?
Wild animals usually enter residential areas because they find resources that support their survival. A property may offer food, water, shelter or an easy route between habitats.
Common attractants include:
Unsecured rubbish and compost.
Pet food left outdoors.
Birdseed and fallen fruit.
Openings beneath decks and sheds.
Damaged roof vents or soffits.
Accessible chimneys and attic spaces.
Standing water and other water sources.
Dense vegetation close to building openings.
Not every animal sighting indicates a problem. A squirrel crossing a fence or a bird feeding in a garden is usually part of normal wildlife activity.
Concerns are more likely when an animal repeatedly enters a structure, establishes a den in an unsuitable location or causes damage.
Ontario’s official guidance on protecting private property from wildlife discusses practical ways to reduce attractants and explains that wildlife handling and relocation are subject to rules.
What Are the Signs of Wildlife in Your Home?
Wildlife may be present inside a building even when the animal is rarely seen. The signs depend on the species, its activity and the location of the shelter.
Possible indicators include:
Unusual Noises
Scratching, rustling, scurrying or thumping sounds may come from an animal moving through an attic, wall cavity or ceiling space. Noise alone cannot identify a species. Several animals, as well as non-wildlife causes, can produce similar sounds.
Droppings and Nesting Materials
Droppings, leaves, twigs, feathers and other debris may indicate animal activity. However, these materials should not be handled without appropriate precautions because their source and potential contamination may be uncertain.
Damage to Roofs and Openings
Loose soffits, damaged vents, displaced roofing materials and gaps around utility lines can provide entry points. Inspecting these areas from a safe position can help identify maintenance needs without disturbing an animal.
Repeated Activity Near One Location
Animals repeatedly entering and leaving the same roofline, vent or sheltered opening may be using it as a regular access point. Observe from a distance rather than approaching the opening or trying to reach inside.
Odours or Damaged Insulation
A persistent unusual odour or disturbed insulation may indicate an animal has occupied an enclosed space. These signs can also have other causes, so further assessment may be necessary.
When wildlife appears to be living inside a building, identifying the species and checking for young or nesting activity are important before deciding on a response.
How to Protect Your Property While Respecting Wildlife?
Preventing wildlife conflicts usually begins with removing attractants and making buildings less accessible. The most suitable approach depends on the animal, the property and any applicable wildlife protections.
Secure Food Sources
Use tightly closed rubbish bins and avoid leaving pet food outdoors overnight. Clean up fallen fruit and spilled birdseed where these attractants are causing recurring wildlife activity. Store food waste appropriately and maintain compost systems according to local guidance.
Close Building Gaps at the Right Time
Repair damaged vents, gaps and other potential entry points after confirming that animals are not trapped inside. Use suitable materials for the location and make sure ventilation and drainage are not obstructed. If an animal may be nesting or raising young, obtain appropriate advice before carrying out exclusion work.
Maintain the Yard
Trim vegetation where it blocks access to building openings, remove unnecessary piles of debris and maintain sheds and other outdoor structures. These steps can reduce some shelter opportunities while allowing wildlife to continue using suitable natural habitat.
Avoid Feeding Wild Animals
Feeding wildlife can encourage animals to gather near people and become dependent on predictable food sources. It can also increase competition between animals and create conditions that attract additional wildlife to a property. Observe animals from a respectful distance and allow them to find food through natural behaviours.
Avoid Poison and Unsafe DIY Methods
Poisons, improvised traps and other hazardous methods can injure wildlife, pets and non-target animals. They may also create legal or environmental problems.
Do not attempt to handle an unfamiliar wild animal or enter a confined space to reach it. If removal or exclusion is necessary, seek guidance from an appropriately qualified professional.
Choose Humane, Species-Appropriate Solutions
Wildlife management should consider animal welfare, the possibility of dependent young, the building’s condition and local requirements. In Ontario, capturing and relocating wildlife is subject to legal restrictions, and the rules can depend on the species and circumstances. Relocation should not be assumed to be a simple or universally permitted solution.
Professional advice can help determine whether exclusion, structural repairs, monitoring or another lawful measure is appropriate.
What Threatens Wildlife Today?
Wildlife faces a range of environmental pressures. The seriousness of each threat depends on the species, location and conditions.
Habitat Loss
Construction, deforestation, drainage and land conversion can remove the food, shelter and breeding areas that animals need. Habitat fragmentation can also separate populations, making it harder for animals to move between feeding and breeding areas. Protecting natural spaces and maintaining connected habitats can help reduce these effects.
Pollution
Plastic waste, contaminated water, pesticides and other pollutants can affect wildlife directly or alter the environments on which animals depend. Animals may become entangled in discarded materials or ingest items they cannot digest. Pollution can also affect food chains and breeding success. Proper waste disposal and responsible product use help reduce avoidable environmental contamination.
Climate Change
Changes in temperature, precipitation and seasonal patterns can affect migration, breeding, food availability and habitat suitability. Some species may adapt or move to new areas, while others may struggle if suitable habitat becomes limited. The effects differ across ecosystems, and many species face several pressures at the same time.
Invasive Species
Invasive species are organisms introduced outside their native range that establish themselves and cause ecological, economic or other harm. They may compete with native wildlife, alter habitats or introduce new pressures into ecosystems. Preventing the spread of invasive species and following local guidance can help protect native biodiversity.
Human-Wildlife Conflict
Conflicts occur when wildlife and people compete for space or when animals damage buildings, crops or other property. Poorly secured food, accessible nesting areas and habitat changes can increase the likelihood of these encounters. Prevention, informed decision-making and appropriate wildlife management can reduce conflicts without treating all wild animals as pests.
How Can You Help Protect Wildlife?
Wildlife conservation does not always require large projects or extensive resources. Everyday choices can help maintain suitable habitats and reduce avoidable harm.
Consider the following actions:
Protect natural habitats. Support the conservation of forests, wetlands, waterways and other important ecosystems.
Plant suitable native vegetation. Choose plants appropriate to your region and growing conditions to provide food and shelter for local species.
Keep rubbish secure. Prevent wildlife from accessing food waste and other materials that can create unhealthy dependencies or dangerous encounters.
Reduce unnecessary pesticide use. Follow product labels and local guidance, and consider non-chemical prevention where appropriate.
Keep a respectful distance. Observe wildlife without chasing, touching or attempting to feed unfamiliar animals.
Protect nesting and breeding areas. Check local rules before disturbing nests, dens or other wildlife shelters.
Report injured wildlife appropriately. Contact a licensed wildlife rehabilitator or the relevant local authority for advice.
Teach children about wildlife. Encourage observation, safe behaviour and respect for living organisms.
Support conservation initiatives. Community cleanups, habitat restoration and reputable conservation programmes can contribute to long-term protection.
Prevent wildlife from entering buildings. Maintain structures, secure food sources and address access points before they become recurring problems.
Small actions can make a meaningful contribution when adopted consistently across households and communities.
