Coyotes are adaptable canids found across North America, often coexisting with deer populations. Their presence raises questions about their impact on deer, particularly regarding active predation. Understanding this dynamic requires examining their dietary habits and influencing circumstances.
The Role of Deer in Coyote Diet
Coyotes consume deer, though it’s not typically their primary food source unless specific conditions exist. Deer meat in coyote diets often comes from scavenging carcasses, such as those from natural deaths, vehicle collisions, or hunter-harvested animals. However, coyotes also hunt deer, especially vulnerable individuals.
While adult deer are part of a coyote’s diet, fawns are more susceptible to predation. Studies show fawn remains are a component of coyote scat during fawning season, in late spring and early summer. In some areas, fawn mortality due to coyotes can be substantial, indicating a direct predatory impact.
Factors Influencing Predation
Several factors influence coyote predation on deer. Deer age and health are determinants; fawns are vulnerable, especially during their first few weeks. Sick or injured adult deer are also more likely targets, presenting less challenge. Research indicates adult deer killed by coyotes often have pre-existing injuries.
Coyote pack size and hunting strategies play a role. While coyotes typically hunt individually, they may cooperate in packs for larger prey like deer. Strategies include running deer until exhaustion or targeting hindquarters.
Seasonal availability of other prey influences their diet; as small mammal populations decline in winter, coyotes may turn to deer. Habitat characteristics also affect predation risk, with fawn survival linked to adequate cover.
Impact on Deer Populations
Coyote predation contributes to natural selection by culling weaker individuals, helping maintain deer herd health. Coyotes can impact fawn recruitment, the number of fawns surviving to adulthood. Studies document fawn mortality rates, with coyotes often identified as a leading cause.
The impact of coyotes on deer populations varies with ecological factors. These include coyote and deer densities, herd health, and environmental conditions like habitat quality and severe weather. While coyotes affect deer numbers, especially fawn survival, large-scale studies suggest they are not the sole cause of declines. Habitat quality and other mortality sources often play a larger role in deer population dynamics.
Beyond Deer: A Coyote’s Diverse Diet
Coyotes are opportunistic omnivores; their diet is adaptable and varied, extending beyond deer. Primary food sources include small mammals like rodents and rabbits. They also consume insects, fruits, and plant materials, demonstrating flexible foraging habits.
Carrion, or decaying animal flesh, is a component of a coyote’s diet, as they readily scavenge. This includes deer that died from vehicle collisions or disease. Their ability to utilize a wide array of food items, from small prey to fruits and carrion, allows coyotes to thrive in diverse environments, from wildlands to urban areas.
