Everything you wanted to know about the coyote...
http://en.wikipedia.org/wiki/CoyoteThe coyote (US: /ka??o?t?i/ or ka??o?t, UK: /k?
?ti/ or k?
?t; Canis latrans), also known as the American jackal or the prairie wolf,[2] is a species of canine found throughout North and Central America, ranging from Panama in the south, north through Mexico, the United States and Canada. It occurs as far north as Alaska and all but the northernmost portions of Canada.[3] There are currently 19 recognized subspecies, with 16 in Canada, Mexico and the United States, and 3 in Central America.[4] Unlike its cousin the Gray Wolf, which is Eurasian in origin, evolutionary theory suggests the coyote evolved in North America during the Pleistocene epoch 1.81 million years ago[5] alongside the Dire Wolf.[6] Unlike the wolf, the coyote's range has expanded in the wake of human civilization, and coyotes readily reproduce in metropolitan areas.[7][8]
The name coyote is borrowed from Mexican Spanish, ultimately derived from the Nahuatl word cóyotl.[9] Its scientific name, Canis latrans, means "barking dog" in Latin.[10] Preliminary genetic evidence, however, has shown that "coyotes" in some areas are, genetically speaking, 85-90 percent Canis latrans, and from ten to fifteen percent Canis lupus, along with some domestic dog DNA; this prompted one researcher to suggest, jokingly, that they be called "Canis soupus," as they are a "soup" (mixture) of canid species.[11]
Though coyotes have been observed to travel in large groups, they primarily hunt in pairs. Typical packs consist of six closely related adults, yearlings and young. Coyote packs are generally smaller than wolf packs and associations between individuals are less stable,[19] thus making their social behavior more in line with that of the dingo.[20] It has been theorized that this is due to an earlier expression of aggression, and the fact that coyotes reach their full growth in their first year, unlike wolves, which reach it in their second.[19] Common names of coyote groups are a band, a pack, or a rout.[21] Coyotes are primarily nocturnal, but can often be seen during daylight hours.[3] Coyotes were once essentially diurnal, but have adapted to more nocturnal behavior with pressure from humans (McClennen et al., 2001).
Coyotes are capable of digging their own burrows, though they often prefer the burrows of groundhogs or American badgers. Coyote territorial ranges can be as much as 19 kilometers in diameter around the den, and travel occurs along fixed trails.[3]
In areas where wolves have been exterminated, coyotes usually flourish. For example, as New England became increasingly settled and the resident wolves were eliminated, the coyote population increased, filling the empty biological niche. Coyotes appear better able than wolves to live among people.[22]
Coyotes have been known to live a maximum of 10 years in the wild and 18 years in captivity.[3] They seem to be better than dogs at observational learning.[17]
