Coyotes are often seen near human settlements, and a puzzling encounter involves them killing chickens without consuming the prey. This phenomenon raises questions, as it seems counterintuitive for a predator to expend energy on a kill only to leave it behind. Understanding this behavior requires looking into the ecology of coyotes, which are highly adaptable and opportunistic predators.
The Instinct to Kill: Understanding Coyote Predation
Coyotes have a strong hunting instinct, fundamental for their survival as medium-sized carnivores. This predatory behavior, shaped by evolution, drives them to secure food for themselves and their offspring. It involves identifying, pursuing, and subduing prey, a complex set of actions honed over generations.
As opportunistic predators, coyotes adapt hunting strategies to available food sources. Their varied diet includes small mammals, insects, fruits, and carrion. This adaptability extends to domestic animals like chickens, an accessible food source.
Killing is a natural part of a coyote’s foraging strategy, separate from immediate consumption. This behavior is rooted in their biology and the need for nutrients. Even when not hungry, the opportunity to secure food can trigger this innate predatory response.
The Puzzle of Unconsumed Prey: Why They Don’t Always Eat
One reason coyotes kill chickens without eating them is surplus killing, also known as the “killer instinct.” This occurs when predators find abundant, easily accessible prey, leading them to kill more than they can immediately consume. Observed in various predators, this behavior is an evolutionary strategy to capitalize on fleeting opportunities.
Coyotes also cache prey, a common practice among canids. After a kill, a coyote might bury or hide prey to return later for consumption. They may kill several chickens, planning to cache them, but then forget the location or cannot retrieve the food.
Disturbance is another factor that can lead a coyote to abandon a kill. Coyotes are wary animals, especially around human activity. If startled by a person, dog, or loud noises while killing or after a kill, a coyote will often flee, leaving the prey rather than risking confrontation.
Younger or less experienced coyotes might also make kills that are not fully utilized. These instances can be part of a learning process, where the coyote practices and refines hunting skills. Such practice kills may not always result in consumption, especially if the animal is still developing efficiency in handling prey.
Finally, a coyote may not consume a killed chicken due to a lack of immediate hunger or alternative food sources. If a coyote has recently eaten or finds easier, less risky food, it may not consume the chicken immediately. The kill might have been opportunistic, but the decision to eat it depends on environmental and physiological factors.
