Urban Wildlife 101: Common Animals and How to Coexist

Urban wildlife refers to the wild animals that live, feed, and reproduce within cities, towns, and suburban areas. This article introduces the most common urban species, explains their behavior and ecological roles, and provides practical strategies for peaceful coexistence. The content is written for students, researchers, life-science professionals, and informed general readers who want to understand urban wildlife dynamics and apply conflict prevention measures in their own neighborhoods or study sites.

Urban environments are evolutionarily novel and differ from natural environments in many respects, including food and water availability, predation pressure, noise, light, air quality, pathogens, biodiversity, and temperature [8]. The success of organisms in urban environments requires physiological plasticity and behavioral adjustments [8]. Some species thrive in these settings while others decline, and understanding which animals persist and why is the first step toward effective coexistence.

What Is Urban Wildlife and Why Does It Matter

Urban wildlife includes all non-domesticated animal species that inhabit human-dominated landscapes. These animals range from birds and small mammals to larger carnivores and ungulates. Cities cover no more than 1 to 2 percent of a typical habitable land mass, yet they have an impact that far exceeds their physical presence [23]. As urban populations grow, the interface between humans and wildlife expands, creating both opportunities and challenges for biodiversity conservation.

Urban green spaces contribute different but collectively important habitats for maintaining and conserving biodiversity in cities [3]. A study of mammal diversity in the greater Chicago region found similar species richness across city parks, cemeteries, golf courses, and natural areas, with the exception of city parks, but remarkably dissimilar communities in different urban green space types [3]. The type of urban green space greatly influenced species colonization and persistence rates [3]. For example, coyotes had the highest probability of persistence in golf courses compared to other green space types, while white-tailed deer had the lowest [3]. Most species had difficulty colonizing city parks even when sites were seemingly available [3].

Urban wildlife matters for several reasons. Wild animals provide ecosystem services such as seed dispersal, pest control, and pollination. They also offer psychological benefits to urban residents. Individuals who devote time to green environments experience significantly reduced stress levels, improved cognitive functions, and improved emotional health compared to individuals who are less exposed to natural environments [18]. Encounters with urban wildlife such as birds and small mammals can help humans feel more connected to nature, and these experiences have been found to be emotionally restorative and less psychologically stressful among urban dwellers [18].

Common Urban Wildlife Species and Their Behaviors

Raccoons

Raccoons are among the most successful urban adapters. They are omnivorous, highly intelligent, and capable of exploiting a wide range of anthropogenic food resources. Raccoons demonstrate flexible movement strategies that explain their urban success [11]. Urban raccoons show a contrasting strategy to other urban mammals, being more active during the day without changes in their movement routines under increasing urbanization, suggesting a flexible strategy that explains their urban success [11].

Raccoons commonly den in attics, chimneys, sheds, and under porches. They are attracted to unsecured garbage, pet food left outdoors, compost piles, and fruit trees. Their dexterous front paws allow them to open containers that other animals cannot access.

Squirrels

Tree squirrels, including gray squirrels and fox squirrels, are ubiquitous in urban parks, residential neighborhoods, and campus settings. They are diurnal and highly visible, making them among the most frequently observed urban mammals. Squirrels benefit from urban tree canopies, bird feeders, and handouts from humans. They nest in tree cavities and leaf nests, and they may enter attics through gaps in rooflines.

Birds

Urban bird communities include both native and non-native species. The bird family Turdidae, known as the true thrushes, includes the blackbird Turdus merula, which has become a textbook case study for understanding how a wild species can deal with urbanization [5]. Research has found evidence for consistent patterns of genetic divergence between urban and rural blackbird populations at an exonic microsatellite associated with the SERT gene, which has hypothesized behavioral effects including harm avoidance that may be associated with tolerating the hustle and bustle of urban environments [5]. This work suggests that urban environments can in some cases exert homogeneous selection pressures [5].

Seasonally breeding urban birds often develop their reproductive system earlier than non-urban birds, perhaps in response to more abundant trophic resources [8]. However, analyses of existing data indicate no general pattern distinguishing urban and non-urban birds in terms of stress physiology or metabolism [8]. The activity of the hypothalamus-pituitary-adrenal axis does not differ consistently between urban and non-urban birds [8].

Foxes

Red foxes are urban dwellers that have adapted successfully to city life. Research tracking movement behavior along an urbanization gradient found that foxes aligned their movement behavior with human activity, having stronger day-night contrasts and more repeatable space use than their rural counterparts [11]. This periodic reorganization of activity timing and space use allows foxes to exploit predictable cycles of resources and risks in urban environments [11].

Foxes are opportunistic omnivores that feed on small mammals, birds, insects, fruits, and anthropogenic food sources. They den in wooded areas, under sheds, and in abandoned burrows. Foxes are generally wary of humans but may become habituated in areas where they are regularly fed.

Coyotes

Coyotes have expanded into urban areas across North America. They are highly adaptable carnivores that can persist in fragmented landscapes. As noted earlier, coyotes had the highest probability of persistence in golf courses compared to other urban green space types in the Chicago region study [3]. Coyotes prey on small mammals, birds, and occasionally pets. They are most active at dawn and dusk and typically avoid direct contact with humans.

White-Tailed Deer

White-tailed deer are common in suburban and peri-urban areas with adequate green space and forage. In the Chicago region study, white-tailed deer had the lowest probability of persistence in golf courses compared to other green space types [3]. Deer can cause damage to gardens, ornamental plants, and vehicle collisions. Their populations can grow rapidly in urban areas where hunting is restricted and natural predators are absent.

Wild Boar

Wild boar are urban utilisers that occur in less predictable suburban environments and avoid city centers [11]. Research on wild boar movement behavior found that they reduced routine movement behaviors with increasing urbanization, consistent with their occurrence in less predictable suburban environments [11]. Wild boar can cause significant damage to parks, gardens, and agricultural areas. They are also involved in human-wildlife conflict in cities such as Bordeaux, France, where modeling of wild boar use of urban nature has been conducted [25].

Free-Roaming Cats

Free-roaming cats, including stray and feral cats, are considered among the 100 worst invasive species and are responsible for the decline and even the disappearance of many wild species worldwide [17]. Free-roaming cats maintain their hunting instincts, causing problems for native species, which is recognized as a major issue in island biodiversity [17]. GPS tracking of free-roaming cats in Cyprus found that males had larger home ranges than females, with median home range sizes of 55,678 square meters for males and 11,377 square meters for females [17]. Daily distance traveled was also higher for males at 1,233 meters compared to 538 meters for females [17]. Activity peaked during the afternoon hours [17].

Free-Roaming Cat Streets, parks, gardens, farmland Food handouts, small prey Hunting instinct, afternoon activity peak Keep cats indoors, support trap-neuter-return programs
Urban Birds Trees, buildings, parks, feeders Bird seed, food scraps, nesting sites Earlier breeding in urban areas Provide native plants, clean feeders regularly, prevent window collisions

Core Principles of Urban Wildlife Coexistence

Understand That Urban Wildlife Is Here to Stay

Urbanization is both a biophysical and a social phenomenon [23]. Among its many measurable physical characteristics are greater concentrations of airborne dust, carbon dioxide, and sulfur compounds and slightly higher precipitation, annual mean temperature, and ultraviolet radiation at ground level than is typical in surrounding hinterlands [23]. These conditions create novel habitats that some species exploit successfully.

Urban wildlife is a permanent feature of city ecosystems. Coexistence requires accepting that wild animals have legitimate ecological roles in urban environments and that management should focus on reducing conflicts instead of removing wildlife.

Recognize the Ecological Roles of Urban Green Spaces

Urban green spaces contribute different but collectively important habitats for maintaining and conserving biodiversity in cities [3]. City parks, cemeteries, golf courses, and natural areas each support different mammal communities with different colonization and persistence rates [3]. This means that preserving a diversity of green space types is important for maintaining urban biodiversity.

For land managers and planners, this principle translates into practical actions. Maintain a variety of habitat types, including wooded areas, grasslands, and water features. Avoid managing all green spaces identically. Preserve connectivity between green spaces to allow wildlife movement and colonization.

Avoid Feeding Urban Wildlife

Food provisioning has the potential to both positively and negatively influence wildlife responses to infection [4]. Food provisioning in field studies tended to increase innate and adaptive responses to certain immune challenges, whereas patterns were less clear in captive studies [4]. Mild food restriction often enhanced immunity, whereas severe food restriction frequently impaired immunity [4]. Trace metals and pharmaceuticals in anthropogenic food can impair the immunity of wildlife species [4].

Feeding urban wildlife creates several problems. It concentrates animals in unnatural densities, increases disease transmission risk, habituates animals to humans, and can lead to nutritional imbalances. Wildlife that becomes dependent on human food sources may lose natural foraging skills and may become aggressive when food is not available.

Manage Anthropogenic Food Resources

Many wildlife species capitalize on anthropogenic food resources [4]. The availability of these resources shapes wildlife behavior, movement, and population dynamics. Managing food resources is one of the most effective ways to reduce human-wildlife conflict.

Practical food management includes securing garbage in animal-resistant containers, removing pet food from outdoors, cleaning up fallen fruit from trees, managing compost piles properly, and not leaving food scraps in parks or green spaces. These measures reduce the carrying capacity of urban areas for opportunistic species and decrease the likelihood of habituation.

Understand Wildlife Movement and Activity Patterns

Human activities in urban areas are strongly periodic, meaning they are predictable in space and time [11]. This may favor species able to adjust their behavior to predictable cycles of resources and risks [11]. Foxes aligned their movement behavior with human activity, having stronger day-night contrasts and more repeatable space use than their rural counterparts [11]. Urban raccoons showed a contrasting strategy, being more active during the day without changes in their movement routines under increasing urbanization [11].

Understanding these movement patterns helps residents and managers predict when and where wildlife encounters are likely. For example, knowing that free-roaming cats in Cyprus are most active during afternoon hours can inform recommendations for keeping pet cats indoors during peak activity periods [17].

Practical Workflow for Assessing and Managing Urban Wildlife Conflicts

Step 1: Identify the Species Involved

Accurate species identification is the foundation of conflict management. Different species require different management approaches. Use field guides, wildlife cameras, tracks, scat, and damage patterns to identify the species involved. Record the time of day when activity occurs, the location of activity, and the type of damage or conflict.

Step 2: Identify Attractants

Determine what is drawing wildlife to the area. Common attractants include unsecured garbage, pet food, bird feeders, compost, fruit trees, gardens, and accessible shelter sites. Walk the property or study area and identify all potential food and shelter resources. Document each attractant and its location.

Step 3: Remove or Secure Attractants

Remove or secure all identified attractants. This may involve installing animal-resistant garbage containers, moving pet food indoors, cleaning up fallen fruit, fencing gardens, and sealing entry points to buildings. This step is often sufficient to resolve conflicts without additional measures.

Step 4: Implement Exclusion Measures

Exclusion prevents wildlife from accessing specific areas. Seal gaps in rooflines, chimneys, vents, and foundations. Install fencing around gardens and compost piles. Use netting to protect fruit trees. Ensure that exclusion measures are installed after confirming that no animals are trapped inside.

Step 5: Monitor and Adjust

Monitor the effectiveness of management measures over several weeks. Record wildlife activity before and after management actions. Adjust strategies based on observed results. Some species may require multiple interventions or different approaches.

Step 6: Escalate to Professionals When Needed

Some situations require professional intervention. Contact wildlife control professionals, animal control agencies, or state wildlife agencies when dealing with injured animals, animals inside buildings, aggressive animals, or species that pose public health risks. Do not attempt to handle or relocate wildlife without proper training and permits.

Records and Measurements for Urban Wildlife Management

Maintaining accurate records is essential for effective urban wildlife management. Records allow managers to track patterns over time, evaluate the effectiveness of interventions, and identify emerging problems.

Wildlife Activity Log

Record the following information for each wildlife observation or conflict event:

Date Time Species Location Activity or Conflict Type Management Action Taken Outcome
2025-06-01 22:30 Raccoon Backyard garbage area Garbage scattered Secured garbage lid No repeat incident
2025-06-03 07:15 Squirrel Attic Scratching noises Sealed roof gap Activity ceased
2025-06-05 18:40 Red fox Garden Digging in vegetable bed Installed fencing Damage reduced

Attractant Inventory

Maintain a current inventory of potential wildlife attractants on the property or in the study area. Include the type of attractant, its location, whether it is currently accessible to wildlife, and the date it was last secured or removed.

Intervention Effectiveness Record

For each management intervention, record the date implemented, the specific action taken, the species targeted, and the outcome observed. Review this record quarterly to identify which interventions are most effective in your specific context.

Common Failure Patterns in Urban Wildlife Management

Inconsistent Attractant Management

The most common failure is inconsistent management of attractants. Wildlife quickly learns when food sources are available intermittently. A garbage container that is secured for one week and then left open the next teaches raccoons to keep checking. Consistency is essential for successful conflict resolution.

Feeding Wildlife Despite Warnings

Some residents continue to feed wildlife despite warnings about the consequences. This undermines neighborhood-wide management efforts and can create problem animals that lose their fear of humans. Education and community engagement are necessary to address this failure pattern.

Improper Exclusion Installation

Exclusion measures that are improperly installed can trap animals inside buildings or create new entry points. Before sealing any opening, confirm that no animals are inside. Use durable materials that wildlife cannot chew through. Inspect exclusion measures regularly for damage.

Relocating Wildlife Without Permits

Relocating wildlife is often illegal without proper permits and is frequently ineffective. Relocated animals may die because they cannot find food, water, or shelter in unfamiliar territory. They may also return to their original territory or cause conflicts in new areas. Professional wildlife control should handle relocation when it is legally permitted and ecologically appropriate.

Ignoring Public Health Considerations

Urban wildlife can be involved in the transmission cycles of numerous pathogens [10]. Wild vertebrates are involved in the transmission cycles of numerous pathogens and can affect the abundance of arthropod vectors [10]. Urbanization, landscape and climate changes, and the adaptation of vectors and wildlife to human habitats represent complex and evolving scenarios that affect the interface of vector, wildlife, and human populations, frequently with a consequent increase in zoonotic risk [10].

Ignoring public health considerations can lead to disease exposure. Never handle wildlife directly. Wear gloves when cleaning areas where wildlife has been present. Wash hands thoroughly after any potential exposure. Seek medical attention for any animal bite or scratch.

Welfare and Safety Context for Urban Wildlife Interactions

Animal Bites and Rabies Prevention

Animal bites are a significant public health concern, particularly in regions with high exposure to domestic and wild animals [14]. A study of animal bites in Sarakhs County, Iran, from 2017 to 2024 analyzed 6,371 recorded cases and found an average annual incidence rate of 790.12 per 100,000 population [14]. The majority of bite victims were male at 78.8 percent, and most incidents occurred in the 20 to 49 age group at 41.5 percent [14]. Students constituted the most affected occupational group at 28.1 percent [14]. Dog bites accounted for 90.1 percent of all cases, and 95 percent of the biting animals were domestic [14]. The most common site of injury was the lower limbs at 57.3 percent [14].

These findings highlight the importance of bite prevention education, particularly for students and young adults. Never approach or attempt to feed wild animals. Keep a safe distance from all wildlife. Supervise children and pets outdoors. Seek immediate medical attention for any animal bite.

Lead Exposure in Urban Wildlife

Urban environments contain significant lead repositories from centuries of human activities, particularly housing and transportation practices from the late 19th century through the 1980s [9]. The urban lead burden is evident among humans, wild and domesticated animals, and plants [9]. Animal lead exposures closely mirror and often exceed the lead exposure patterns of their human partners [9]. Pigeons in New York City neighborhoods mimicked the lead exposures of neighborhood children, with more contaminated areas associated with higher exposures in both species [9].

Lead pollution is not distributed evenly across urban areas [9]. Neighborhoods with disproportionate commercial and industrial lead activity, a history of dense traffic, older and deteriorating housing, past and operating landfills, dumps and hazardous waste sites, and often lead-contaminated drinking water tend to have higher lead exposures [9]. The population there tends to be low income and minority [9]. Urban wild and domesticated animals bear that same lead burden [9].

For those who handle urban wildlife or consume wild game from urban areas, lead exposure is a concern. Soil, buildings, dust, and even trees constitute huge lead repositories throughout urban areas [9]. Wash hands after handling wildlife or soil. Do not consume wild game harvested from contaminated urban areas.

Zoonotic Disease Awareness

Human-animal contact is a key driver of zoonotic disease emergence and transmission [13]. A cross-sectional study in wildlife-rich areas of Bolivia, Chile, and Guatemala surveyed 2,389 participants and found that 92 percent reported domestic animal contact, most frequently with dogs, cats, poultry, and swine, while 32 percent reported wild animal contact, predominantly with wild birds, rodents, and bats [13]. Ninety-nine percent of individuals with wildlife contact also reported contact with domestic animals [13]. Direct interactions, including ownership, handling, and slaughtering, were most common [13].

Adolescents and participants with lower income and education showed higher exposure scores [13]. Rural residence was associated with greater exposure to brucellosis and bovine tuberculosis, and prior zoonosis training was associated with lower exposure to rabies [13]. These findings underscore the importance of zoonosis education, particularly for young people and underserved communities.

Avian Influenza Considerations

Highly pathogenic avian influenza outbreaks pose significant threats to animal and human health [12]. Risk assessment and prediction modeling are essential for improving disease control and enabling timely intervention strategies [12]. A study integrating HPAI outbreak data collected over 16 years with meteorological data, wild bird nest proximity, and confirmed outbreak locations identified metropolitan areas and coastlines as the most vulnerable locations for HPAI outbreaks [12].

For those who keep poultry or interact with wild birds, awareness of avian influenza risk is important. Avoid handling sick or dead wild birds. Report unusual bird deaths to local authorities. Practice good biosecurity around domestic poultry.

Urban Wildlife Signage and Community Communication

Signage functions as a governance instrument that encodes environmental values into urban spaces [20]. Research on urban wildlife signage preferences involving wild boars in Mount Carmel and Nesher, Israel, found that higher perceived harm is associated with stronger anthropocentric preferences, and this relationship is partly transmitted via support for local environmental morality policies and is conditioned by political ideology [20]. Biocentric preferences co-occur with instructional and informational content, softer color palettes, family-oriented iconography, and humorous tones [20].

Anthropocentric signage highlights human safety and casts wildlife as hazardous or problematic, while biocentric signage underscores coexistence, ecological interdependence, and shared constraints [21]. The choice between these approaches reflects deeper social, environmental, and political dynamics [21].

For communities developing wildlife signage, consider the following:

  • Assess the level of perceived harm in the community before choosing signage language
  • Use instructional and informational content for biocentric messaging
  • Consider color palettes, iconography, and tone that match community values
  • Involve community members in signage design to increase acceptance
  • Evaluate signage effectiveness and adjust as needed

Urban Wildlife and Environmental Contaminants

Cannabis Cultivation and Wildlife Habitat

Policy fragmentation contributes to the myriad environmental impacts of the cannabis industry and impedes solutions [7]. A key determinant of environmental problems is whether cannabis cultivation is conducted indoors or outdoors in open fields [7]. Emissions of greenhouse gases are approximately 100 times greater for indoor cultivation, and water use is higher when accounting for water associated with power production [7]. Other distinct spheres of impact involve land use, waste production, air pollution, ecosystem degradation, and adverse indoor environmental quality conditions faced by workers [7].

For urban wildlife, outdoor cannabis cultivation can affect habitat and water resources. Land use changes associated with cultivation can fragment wildlife habitat. Water withdrawals can affect aquatic ecosystems. Pesticide use can contaminate soil and water. These impacts should be considered in urban planning and wildlife management.

Mosquito Habitats in Urban Areas

Anthropogenic activities cause changes in natural environments, affecting the ecology of Anopheles mosquitoes and, therefore, increasing the potential for malaria transmission [15]. A study of Anopheles larval habitats in northwestern Argentina found that peri-urban habitats comprising puddles, ponds, and irrigation and drainage channels supported different anopheline species than wild or peri-rural habitats [15]. In the peri-urban habitat, mean temperature was positively associated with Anopheles strodei and Anopheles evansae [15].

Urban wildlife management should consider vector ecology. Standing water in urban areas can support mosquito populations that transmit diseases to humans and wildlife. Eliminating standing water, maintaining drainage channels, and managing irrigation practices can reduce mosquito habitat and disease risk.

Urban Wildlife Conservation and Planning

Integrating Wildlife Conservation into Urban Planning

Wildlife conservation should be integrated into urban planning processes [26]. This integration requires collaboration between ecologists, planners, and policymakers. Urban planning decisions about land use, green space preservation, building design, and infrastructure development all affect urban wildlife populations.

Practical integration strategies include:

  • Conducting wildlife surveys before development projects
  • Preserving existing green space and habitat connectivity
  • Designing buildings and infrastructure to minimize wildlife conflicts
  • Incorporating wildlife considerations into zoning and land use regulations
  • Engaging communities in wildlife conservation planning

Urban Wildlife Communication and Negotiation

Effective urban wildlife management requires communication and negotiation among stakeholders [29]. Residents, property managers, wildlife professionals, and government agencies often have different perspectives on wildlife issues. Successful management depends on finding common ground and developing solutions that address multiple concerns.

Communication strategies include public education campaigns, community meetings, signage, and digital tools. The Malang Wildlife App provides an example of using technology to increase knowledge and involvement in preserving and protecting rare animals [22]. The app provides information about data from trusted sources and makes it easier for users to access information [22].

Religious and Cultural Responses to Urban Wildlife

Urban wildlife issues have religious and cultural dimensions [28]. Different communities may have different values and beliefs about wildlife that affect their willingness to support management measures. Understanding and respecting these values is important for developing culturally appropriate management strategies.

Wildlife in Times of Reduced Human Activity

The onset of the COVID-19 pandemic brought an unusual decrease in human activity associated with partial and total lockdowns [24]. A series of wildlife sightings, mainly in urban areas, were brought to public attention and often attributed to lockdown measures [24]. Camera traps set in urban forests, campuses, suburbs, and peri-urban areas of two cities in Chile detected four native carnivores, including the vulnerable güiña and the endangered southern river otter [24].

However, these findings cannot be used to argue for or against an effect of lockdown measures on wildlife [24]. Caution is warranted in the interpretation of seemingly novel carnivore records during periods of lockdown [24]. This example illustrates the importance of rigorous scientific methods in urban wildlife research.

Limitations of Current Urban Wildlife Knowledge

Research Gaps

Current understanding of urban wildlife has significant limitations. Many studies are correlative instead of aiming at establishing causality, which effectively limits our ability to formulate specific hypotheses regarding the impacts of urbanization on wildlife [8]. Future research will benefit from prioritizing mechanistic approaches to identify environmental factors that shape the phenotypic responses of organisms to urbanization and the neuroendocrine and metabolic bases of these responses [8].

It will be critical to elucidate whether factors affect these responses cumulatively or synergistically and differentially as a function of age and other variables [8]. Research on food provisioning and wildlife immunity also stresses a need for further research, especially field studies, and highlights the importance of integrating nutritional manipulation, immune challenge, and functional outcomes [4].

Geographic Bias

Much urban wildlife research has been conducted in North America and Europe. Studies from the Global South are less common but are increasing. The Chile study on urban carnivores noted that urban carnivore ecology is mostly unknown in that country [24]. The Bolivia, Chile, and Guatemala study on human-animal contact noted that population-based data from Latin America remain limited [13]. Expanding research to underrepresented regions is essential for developing globally applicable urban wildlife management strategies.

Species Bias

Research tends to focus on charismatic or conflict-prone species such as foxes, raccoons, coyotes, and deer. Less attention has been paid to small mammals, reptiles, amphibians, and invertebrates that also inhabit urban areas. Tree cavity availability and distribution across habitats in Udaipur, a small Indian city, provides an example of research on habitat features that support urban wildlife [19]. Understanding the full range of urban biodiversity requires studying a wider range of taxa.

Professional Escalation Criteria

When to Contact Wildlife Professionals

Contact wildlife control professionals, animal control agencies, or state wildlife agencies in the following situations:

  • An animal is injured and requires medical attention
  • An animal is trapped inside a building
  • An animal is behaving aggressively toward humans or pets
  • A wild animal bites or scratches a person
  • A sick or dead animal is found and the cause is unknown
  • A species is present that poses a significant public health risk
  • Repeated conflicts occur despite implementing recommended management measures

When to Contact Medical Professionals

Seek immediate medical attention for any animal bite or scratch. Rabies is a fatal disease, and post-exposure prophylaxis is time-sensitive. Wash the wound thoroughly with soap and water and seek medical care as soon as possible. Report the incident to local animal control authorities.

When to Contact Public Health Authorities

Contact public health authorities when there is evidence of disease in urban wildlife populations, when unusual wildlife mortality is observed, or when there is potential for zoonotic disease transmission to humans. Early reporting can facilitate rapid response and prevent disease spread.

Frequently Asked Questions

What is urban wildlife?

Urban wildlife refers to wild animal species that live, feed, and reproduce within cities, towns, and suburban areas. These include mammals such as raccoons, squirrels, foxes, coyotes, and deer, as well as birds, reptiles, amphibians, and invertebrates. Urban wildlife species have adapted to human-dominated environments and often exploit anthropogenic food resources and shelter sites.

Why do some animals thrive in cities while others do not?

Urban environments are evolutionarily novel and differ from natural environments in many respects, including food and water availability, predation, noise, light, air quality, pathogens, biodiversity, and temperature [8]. Species that thrive in cities typically show behavioral flexibility, such as adjusting their activity patterns to human schedules [11]. Foxes align their movement behavior with human activity, while urban raccoons show flexible strategies that explain their urban success [11]. Species that cannot adapt to these novel conditions tend to decline or disappear from urban areas.

Is it safe to feed urban wildlife?

Feeding urban wildlife is not recommended. Food provisioning has the potential to both positively and negatively influence wildlife responses to infection [4]. Anthropogenic food can contain trace metals and pharmaceuticals that impair the immunity of wildlife species [4]. Feeding concentrates animals in unnatural densities, increases disease transmission risk, habituates animals to humans, and can lead to aggressive behavior. It is better to manage food resources by securing garbage and removing attractants.

What should I do if I find an injured wild animal?

Do not handle the animal directly. Contact a licensed wildlife rehabilitator, animal control agency, or state wildlife agency for guidance. If the animal is a threat to public safety, contact local authorities immediately. Keep children and pets away from the animal. If you must move the animal for safety reasons, wear thick gloves and use a container or barrier to avoid direct contact.

How can I prevent raccoons from getting into my garbage?

Use animal-resistant garbage containers with secure lids. Place garbage out for collection in the morning instead of the night before. Store garbage in a shed or garage if possible. Clean containers regularly to remove food odors. Consider using bungee cords or locking mechanisms on lids. Remove other attractants such as pet food and fallen fruit from the area.
