With their slender build and filthy coats, coyotes are sometimes seen as the scrappy and sneaky counterpart to more noble canines like wolves and domesticated dogs. Known for their prodigious cunning and their hauntingly distinct howl, the coyote has been revered in some Native American cultures as a trickster spirit and reviled by ranchers as a nuisance.
But beyond the coyote’s legend and reputation lies a lot of misinformation. This dog’s reputation as a trickster reflects a sharp mind and an adaptable personality that allowed them to adapt to human encroachments better than other animals. And while coyotes can really spread disease and affect ranchers’ livelihoods by preying on livestock, that doesn’t do justice to the complex and often beneficial effects coyotes have on their habitats. But the facts behind how coyotes hunt and interact with their packs can tell us a lot about who these animals really are.
Why animals hunt in packs
Virtually any behavior in the wild can be assessed in terms of risk and reward. the krill shrimp that’s the biggest part of a flamingo diet gives them bright pink feathers that stand out from predators, but it is also a readily available food source that can be bred in waters deep enough to protect flamingos from predators. Flamingos further increase their chances of survival by foraging in flocks, but most prey species do not have that advantage.
Grazing animals like llamas and bison usually gather in herds, both because it allows them to spot predators more easily in open plains and because it shares the risk of being preyed upon individually. And by foraging and migrating together, prey species can also minimize the energy costs of foraging for food. The consistency and scale of this group behavior is limited by the amount of resources available, and predation plays an important role in preventing herds from overgrowth and overgrazing.
That calculation of weighing energy consumption against the value of food is also what drives predators to gather in packs. Although group foraging behavior is the standard for most prey species, most predator species are solitary hunters. This can be attributed to a phenomenon known as economic defensibility, which is simply a cost-benefit analysis of maintaining a territory — the functional equivalent of having roommates or not. As with prey animals, the most important factor to consider is the availability of food. In environments where prey resources are scarce, territoriality is usually fiercest and deadliest. If a predator can protect a territory large enough to support its hunger and shelter needs, there is little need for cooperating with another predator. But solitary doesn’t necessarily mean antisocial, and some predators can overlap in territory if there isn’t an immediate conflict of interest. This is most evident in shared but abundant resources such as waterholes and large carcasses. As a particularly dramatic example bears and wolves have witnessed feeding in peace with the corpse of a stranded humpback whale.
The biggest lure for a predator to develop pack hunting tactics is the availability of big game. African lions are the main predator of the approximately two tons giraffe – a seemingly sensible choice, as a single adult could feed a pride of lions. It is a very dangerous hunt that can take all the pride and energy, so giraffes are only hunted when smaller prey is scarce. Even when hunted in packs, social structure and size are generally designed to maximize hunting efficiency. Wolves are among the most effective pack hunters in the world, thanks in large part to their sophistication and patience. A pack can stay behind for weeks and moose herd, observe the crowd for particularly vulnerable prey and evaluate weather and terrain conditions before planning their attack. And once they do, successful wolf packs will operate as orchestrated and tactical hunters who can improvise when needed. Pop culture tends to characterize wolves as loyal and devoted relatives and coyotes as seedy loners, but these canines are closely related to the breed. The facts tell a complicated story.
Do Coyotes Hunt in Packs?
Environmental conditions and food and habitat scarcity can have a dramatic impact on how a species develops its social and food-gathering behavior, and coyotes have been able to adapt exceptionally well thanks to being highly opportunistic predators. There is a common understanding that coyotes are hungry scavengers that live primarily on garbage and pets. It may seem like a valid point if you look at a lot of urban eat coyotes up to 25% human waste, but it doesn’t do justice to the complex adaptability of the coyote’s hunting methods. Urban coyotes are often solitary hunters that live on human food scraps because that’s what’s available, but the story gets considerably more complex when you look at the bigger picture.
The coyote’s habitat now extends from Canada through the United States and Mexico and in Central America, and it includes mountains and forests despite the coyote’s preference for desert and plains. While they sometimes come together in packs to hunt larger game, such as deer, they are more likely to hunt alone or with a mate. As with the lion and giraffe, the risk and energy investments are too high risk. Being smaller than a wolf’s cousin creates disadvantages for hunting larger game, but it also leaves them with lower nutritional needs and greater availability of viable food sources.
With their wiry bodies and nervous agility, they are capable of hunting rabbits, snakes, rats, and squirrels down and are known to prey on birds such as sparrows also. These canines won’t pass up a free meal, even in the form of road deaths or another animal’s trophy, but they won’t ask for a meal card. As omnivores, 10% of their diet consists of berries, fruits and grasses. Being small may seem like a disadvantage at first, but the facts show that coyotes have exploited an apparent weakness for cross-continental expansion. Hunting large pr
ed
ators is simply rarely the best option available. Coyotes will instead forage and hunt in pairs, scouring the environment for prey and locations to forage and working together to flush out and kill smaller animals.
Why coyotes gather in packs
Numerous active efforts to eradicate the coyote population have been made over the years, but they have only increased in both population and geography. Today, federal efforts that kill thousands of coyotes a year are only meant to keep the population in check — and they’re largely ineffective at that. Coyotes simply don’t die, and the sophistication and flexibility of their social structure plays a big part in their perseverance.
Because while they may rarely benefit from pack hunting, coyotes have much to gain from the fringe benefits of cooperation. Most coyotes belong to a pack that will generally consist of five or six adults and the last litter of puppies. A monogamous alpha breeding pair forms the core of each pack, reducing the threat of overpopulation of the pack’s territory. The typical territory can range from 5 miles to three times the size or about the size of a jaguar‘s territory.
The pack may hunt alone, but they work together to protect their territory. Threats can come in the form of lone coyotes, breeding pairs seeking territory, or larger predators such as wolves. Territorial disputes can get heated, but they’re made rarer by the fact that territories often don’t overlap. The space between these territories is often shared by several packs in relative peace, although this is highly dependent on current hunting and foraging conditions. Joining a pack benefits the lone coyote, who could otherwise offend multiple alpha coyotes in a single area of hunting grounds.
It’s also a compelling argument to stick with the group you were born into. Pack members outside the alpha pair are often adult children of the pair, although they can also be unrelated coyotes who have joined the pack out of mutual expediency. Since a coyote litter is typically four to seven pups, there is only so much room. When puppies reach adulthood at about nine months, most will head out to find a mating partner and a territory or
The coyote’s vision as a loner trickster is romantic and rewarding, but it shows us only one side of a socially complex animal. Research into the coyote’s aggressive population revealed that actively killing coyotes only disrupted their social structure and their chosen breeding. Members of packs that were previously satisfied instead leave to find new packs or breeding partners. The coyote’s success comes down to the fact that they adapt well to the environments in which they roam, creating largely regulated territories. Coyote raids on cities and attacks on livestock are real problems, but each new understanding about these creatures brings us closer to sustainable solutions.
