Why is the coyote endangered

Additionally, researchers evaluated the prevalence of West Nile virus, tularemia and canine heartworm. Coyotes are useful as sentinels due to their exposure to multiple species of rodents, as well as directly to black-footed ferrets through predation. The use of other sentinel species for disease surveillance among endangered animals is an important conservation tool, Schuler said.

Rachel Abbott, an author on the study. While the study does not name a definitive cause of the decline in this population of black-footed ferrets, it highlighted the range of pathogens that may be affecting them as well as other species in the ecosystem. The black-footed ferret is a nocturnal ferret native to grasslands of the central United States, Canada and northern Mexico.

During summer and fall, they also eat grass, fruits and berries. They may also eat pet food, garbage, garden crops, livestock and poultry. Most hunting activity takes place at night. Undisturbed, hungry coyotes may hunt during daylight hours, and sometimes follow farm machinery, catching voles and other small prey.

In winter, when snow depth restricts the movements of deer, these animals may become a larger part of a coyote's diet. Pairs of coyotes or family groups, using the relay method, pursue deer. In the spring and summer coyotes may target deer, fawns and small mammals. Coyotes are medium in size.

They have pointed muzzles and long, brushy tails. Their coats are usually a mixture of tan, black, and gray, but can range from black to strawberry blond. The average Eastern adult coyote weighs 30 to 35 pounds, with males being heavier than females. Large males only rarely will exceed 45 pounds.

In comparison, Western coyotes weigh pounds on average and have a more consistent tan coat color. Coyotes are most active hunters during dawn and dusk hours but may have more nocturnal habits when they live in close proximity to humans to avoid conflict. Coyotes are known for how well they adapt to different habitats. They can even be found living in and around large cities. In the Sonoran Desert, coyotes can be found in all habitats from desert scrub, grasslands, foothills as well as in populated neighborhoods.

Coyotes are omnivores, which means they will eat or try to eat just about anything. In the Sonoran Desert coyotes vary their diet with the seasons. Cactus fruit, mesquite beans, flowers, insects, rodents, lizards, rabbits, birds, and snakes make up some of their dietary choices.

The most common enemy that coyotes face is disease. Bears, wolves and mountain lions will also prey upon coyotes.

Humans pose problems for coyotes as they try to navigate across our busy roads. Many coyotes are struck and killed by cars every year. But biologists who study this estimate say that, at taxpayer expense, Wildlife Services aerial guns about 80, coyotes per year on behalf of the livestock industry.

Coyotes have been living in cities in America for at least a thousand years. Coyotes in rural America usually live on average only about two and a half years.

As they have moved east, they have also encountered two remnant species of American wolf: the red wolves of the South and the Eastern wolves of upper New England and eastern Canada. There are no behavioral barriers to them interbreeding. Project Coyote is one of a number of conservation organizations devoted to bringing back the coyote—tell us about these efforts and why it is important to save what you call an "American avatar.

Project Coyote, which is based in San Francisco, is trying to get us to understand how we can coexist with these animals and not react to them out of fear or stereotypes: that they have rabies or eat at the back of fast-food restaurants.

They are predators of small rodents. The coyote is our classic totem animal in America. To me, the howl of the coyote is our original national anthem. Simon Worrall curates Book Talk.
