12/9/2023 0 Comments Coyote natural predators![]() For the most part, predation by natural species is thought to represent only a minor role in the mortality of feral hogs throughout their range. However, man is still unquestionably the primary and most significant predator of non-native feral hogs. ![]() The study is published in the journal PeerJ.Ĭheck us out on EarthSnap, a free app brought to you by Eric Ralls and .īy Andrei Ionescu, Earth.Feral hogs (also called wild hog Sus scrofa) are preyed on by several natural (that is, nonhuman) species of carnivores and omnivores in the United States. This study highlights the importance of creating and maintaining green spaces where wildlife can thrive,” she concluded. Instead, coyotes are eating natural food items that are available in the city parks. “Our results show that coyotes are not reliant on human food to survive in New York City. By predating on raccoons, coyotes are helping to provide healthy ecosystems.” Raccoons can carry diseases such as rabies and canine distemper that can be transmitted to humans and pets. “With no other natural predators to limit their populations, coyotes provide an important ecological service. “Raccoons were the most prevalent mammal detected in the New York City coyote diet,” Dr. Although both groups of coyotes ate similar proportions of human food (about 60 percent of the fecal samples contained traces of at least one human food item), the urban coyotes ate a wider variety of such products, including rice, goat meat, guineafowl, or bananas. The scientists also compared the diet of NYC coyotes to that of coyotes living in non-urban areas from the New York state, and found that raccoons and deer made up a larger proportion of the diet of non-urban coyotes compared to that of their urban relatives. There are no wild cows, chickens, or banana trees in NYC parks so if we got a DNA hit on something like that, we knew that the coyote had eaten from an anthropogenic source,” Dr. “What’s unique about our study is that by sequencing the DNA of coyote scat we were able to detect diet items that might not be detected through a visual analysis of the scat samples, such as specific human food items. However, they also ate birds, insects, plants, as well as human-sourced foods like beef, pork, or chicken. The analyses revealed that urban coyotes consumed a wide variety of mammalian prey, including racoons, rabbits, deer, and voles. To find out what New York coyotes are eating, the researchers analyzed DNA from coyote fecal samples collected in parks and other green spaces between 20. Although previous research conducted in cities such as Los Angeles and Chicago have found that coyotes eat mainly “natural” foods such as rabbits or rodents, city coyotes still tend to consume more human-sourced food items than their countryside counterparts. “Knowing what the coyotes are eating can help inform management practices by city officials.”Ĭoyotes are opportunistic omnivores, usually taking advantage of whatever food is available. “Urban areas have lots of people and thus greater availability of anthropogenic foods,” said study lead author Carol Henger, a postdoctoral fellow at the Wildlife Conservation Society. Now, by analyzing the DNA of urban coyotes living in New York, a team of experts discovered that they eat a variety of native prey species and only supplement this diet with human-sourced food items. ![]() Since urban coyote research began in the 1980s and 1990s, there has been a sustained interest in the scientific community in what type of foods coyotes living in urban areas are eating, specifically whether they are relying on human foods for sustenance.
