How Pollution Impacts Coyotes' Survival

Coyotes are highly adaptable and resilient creatures, thriving in a wide range of environments across North America. While they are skilled hunters, they are vulnerable to a variety of threats, including natural predators, human activity, and conflicts within their species. Human activities, such as pollution, wealth distribution, and population density, have been found to significantly influence coyote behaviour and movement patterns. This raises the question of whether pollution, in particular, contributes to coyote mortality and how it interacts with other factors to shape coyote survival in urban environments.

Coyotes are killed by other coyotes, wolves, cougars, bears, and eagles

Coyotes are highly adaptable and fierce predators, but they are not exempt from being preyed upon by other animals. The coyote's biggest enemy is the grey wolf, which is dominant in many ecosystems and can easily outcompete coyotes for food and territory. In fact, the reintroduction of wolves in the Lamar River Valley led to a 40% decline in the coyote population. Coyotes sometimes mate with grey wolves, producing "coywolf" hybrids.

Other than wolves, common coyote predators include cougars (also known as mountain lions), bears, golden eagles, and Canadian lynxes. Cougars are large carnivores and apex predators in many ecosystems. They primarily prey on ungulates such as deer but will also target smaller animals like coyotes. Bears, eagles, and lynxes are also known to prey on coyotes, especially when the coyotes are working alone or in the form of pups.

In addition to these natural predators, coyotes face significant threats from human activities such as habitat destruction, hunting, and urbanization. Human population density and development intensity have been found to strongly influence coyote movement and habitat selection. Wealth and pollution levels in an area can also impact coyote behavior, with coyotes in highly polluted and developed areas displaying larger home ranges and higher exploration tendencies.

While coyotes are adaptable and can be found in various habitats, they are not at the top of the food chain in most ecosystems. As such, they must navigate a range of potential threats and competitors, including other predators like wolves and cougars. Coyotes may be able to escape or defend themselves from these predators if they are in a pack, but they will typically flee or avoid confrontation with larger or more aggressive animals.

Overall, while coyotes are skilled hunters themselves, they are also vulnerable to being hunted by other predators in their ecosystems. The impact of human activities on coyote behavior and movement patterns further complicates their ability to navigate these threats.

Humans are the greatest threat to coyotes, hunting and trapping them for their fur, and as threats to livestock

While coyote attacks on humans are rare, they do pose a threat to children and pets. Coyotes are wild animals and should be treated as such. They are also known to attack other animals, including pets, and even kill them. While they are generally wary of humans, they can become a nuisance or a threat, especially in urban areas.

Human activities and choices have a significant influence on habitats and wildlife behavior, including that of coyotes. A study by the California Academy of Sciences and UC Berkeley found that wealth, pollution, and population density are strong predictors of coyote movement in Los Angeles. Coyotes in areas with higher pollution and development intensity display different movement patterns, with larger home ranges and higher exploration tendencies. Human population density and development intensity were found to be the strongest influences on coyote behavior and habitat selection.

Coyotes are often hunted and trapped by humans, either as a threat response or for their fur. While some people intentionally feed coyotes, which can lead to them losing their fear of people and considering humans as potential prey, others unintentionally feed them by leaving pet food or garbage out at night. This can attract rodents and squirrels, which in turn attract coyotes.

To avoid conflicts with coyotes, it is important to understand their behavior and respect their space. In most cases, the removal of a non-dangerous coyote is the responsibility of the individual homeowner, who may need to contract a licensed wildlife trapper. However, it is generally recommended to leave coyotes where they are, as their removal does not guarantee the absence of coyotes in the area. Education and fostering mutual respect through our behavior are crucial in preventing conflicts with coyotes.

Coyotes are resilient and adaptable, thriving across a wide range of environments

Coyotes are highly adaptable and resilient, with a remarkable ability to thrive in a wide range of environments. They have long been associated with the American West, but their range has expanded far beyond that. Today, coyotes can be found across all the lower 48 states of the US, as well as Alaska, Canada, Mexico, Central America, and likely beyond. They occupy a diverse array of habitats, from grasslands and deserts to urban parks and cities.

Coyotes are opportunistic omnivores, and this adaptability in their diet has allowed them to adjust to human-altered landscapes. They primarily feed on rodents, but will also eat insects, vegetables, and fruit. This ability to survive on whatever food is available has brought them into closer contact with humans, as they venture into cities and suburbs in search of sustenance. For example, coyotes have been spotted in New York City's Central Park and across urban areas in Los Angeles.

The Navajo people revered coyotes as "God's dog", and they are indeed remarkably resilient. Despite over a century of extermination efforts, coyotes have expanded their range threefold since the 1850s. They have even colonized offshore islands, as they are known to be good swimmers. Coyotes have proven intelligent and resourceful, outwitting many attempts to exclude them from human spaces.

Research has shown that wealth, pollution, and population density influence coyote movement patterns. Coyotes in highly polluted and developed areas display different behaviors, with larger home ranges and longer step lengths, possibly due to the need to navigate scattered resources and disturbances. Despite these challenges, coyotes play an essential role in maintaining healthy ecosystems and species diversity, even in fragmented and urbanized landscapes. They help regulate mesocarnivore populations, including mid-sized predators like foxes and raccoons.

In summary, coyotes are highly adaptable and resilient creatures, capable of thriving in a wide range of environments, from rural grasslands to densely populated cities. Their intelligence, resourcefulness, and dietary flexibility have ensured their survival and expansion, even in the face of human-induced threats and challenges.

Wealth, pollution, and population density influence coyote movement, with coyotes avoiding wealthier areas

Coyotes are resilient creatures that have thrived in a wide range of environments across North America. They are skilled hunters, but they are also vulnerable to various threats, including natural predators, human activity, and conflicts within their species. While humans are the single greatest threat to coyotes, other factors, such as wealth, pollution, and population density, also influence their movement patterns.

A recent study by the California Academy of Sciences and UC Berkeley specifically examined the impact of these factors on coyote behaviour in Los Angeles. The research, led by Christine Wilkinson, PhD, utilized GPS collars to track coyote movement and found that wealthier areas with higher pollution and development intensity exhibited different coyote movement patterns. Coyotes in these areas had larger home ranges, longer step lengths, and higher values of mean daily displacement, indicating a need to navigate scattered resources and respond to disturbances.

Interestingly, the study also revealed that coyotes tended to avoid higher-income areas, contrary to the "luxury effect" hypothesis, which suggests that wealthier neighbourhoods have higher biodiversity. This finding highlights the complex interplay between societal and ecological factors in shaping coyote behaviour. By integrating information about regional landscapes, linear infrastructure, and societal data points, researchers were able to develop more accurate predictions of coyote movement.

The impact of roads and railways on coyote behaviour has been previously understudied, and this research contributes to a growing understanding of how human-driven inequities affect environmental, wildlife, and human health. While the study focused on urban areas, it is important to recognize that coyote behaviour is highly variable and influenced by various ecological and societal factors. Further research is needed to fully comprehend how these factors interact to shape coyote movement and habitat selection in different regions.

Coyotes are a potential danger to humans, especially children, but attacks are rare and preventable through human behaviour modification

Coyotes are wild animals that are potentially dangerous to humans, especially children and pets. While attacks on humans are rare, they do happen. There have been very few recorded situations where a human has been killed by coyotes—according to the Humane Society, there have been two recorded cases in the US or Canada, and three reported human deaths caused by coyotes. However, coyotes are more likely to attack children and pets.

Coyotes have been known to frequent residential areas and have become a regular sight in some urban areas, such as Los Angeles. Their presence in these areas can be influenced by various factors, including wealth, pollution, and population density. Research has shown that coyotes living in areas with higher pollution and development intensity display different movement patterns than those in less burdened areas. They tend to have larger home ranges and longer step lengths, which may be due to the need to navigate scattered resources and respond to disturbances.

To prevent coyote attacks and conflicts, it is important to modify human behaviour. The most effective way to do this is to eliminate wildlife feeding. Coyotes that are fed in residential neighbourhoods can lose their fear of people and may start to see humans as potential prey. Intentional feeding, such as bait stations in yards or parks, should be avoided, as well as unintentional feeding, such as leaving pet food or garbage out at night. Bird feeders should also be avoided, as they can attract rodents and, in turn, coyotes.

It is also important to keep pets secure and not let them roam loose, as they can attract coyotes and fall prey to them. When hiking in parks, keep dogs on leashes. Electric fences may contain your pets, but they will not keep other animals out. Free-roaming domestic cats and feral cat colonies can also attract coyotes, so it is important to keep domestic cats indoors and control the feral cat population through spaying or neutering.

In most cases, the removal of a non-dangerous coyote is the responsibility of the individual homeowner, who may need to contract a licensed wildlife trapper. However, it is often best to leave coyotes where they are, as the removal of one animal does not ensure the removal of all coyotes from the area. Instead, focus on prevention and modifying human behaviour to reduce the risk of conflicts and attacks.
