The coyote, prairie wolf or brush wolf, is a canine native to North America. Coyote males average 8 to 20 kg in weight, while females average 7 to 18 kg. Body length ranges on average from 1 to 1.35 m, and tail length 40 cm, with females being shorter in both body length and height. Scent glands are located at the upper side of the base of the tail and are a bluish-black color.[7
When hunting large prey, the coyote often works in pairs or small groups. Success in killing large ungulates, depends on factors such as snow depth and crust density. Younger animals usually avoid participating in such hunts, with the breeding pair typically doing most of the work. Unlike the wolf, which attacks large prey from the rear, the coyote approaches from the front, lacerating its prey’s head and throat. Like other canids, the coyote hides excess food.
Coyotes catch mouse-sized rodents by pouncing, whereas ground squirrels are chased. Although coyotes can live in large groups, small prey is typically caught singly. Coyotes have been observed to kill porcupine in pairs, using their paws to flip the rodents on their backs, then attacking the soft underbelly. Only old and experienced coyotes can successfully prey on porcupines, with many predation attempts by young coyotes resulting in them being injured by their prey’s quills.
