An adult male wolf usually weighs 75 to 120 pounds; females weigh between 60 and 95 pounds. This may be smaller than some breeds of dog! Wolves lose some insulating fat and shed much of their fur in the summer, and weigh less than. Also, wolves that live in the cold north are generally larger and heavier than wolves that live in warmer climates.
Wolves live in all kinds of terrain, from desert to tundra. They prefer areas with cover (places to hide such as brush, shrubs, or trees), near water, and near large congregations of prey (herds of deer or caribou, for example).
Wolves primarily eat meat. Their favorite prey is large ungulates (hoofed mammals) such as deer, elk, moose, caribou, and bison. Since many of these animals are larger than wolves, the only way wolves can catch them is to live and hunt in groups. Wolves will also catch and eat rabbits, mice, birds, snakes, fish, and other animals. Wolves will eat non-meat items (such as vegetables), but not often.
Even working together, it is hard for wolves to catch their prey. Healthy deer can easily outrun wolves, and large animals like moose or bison often stand their ground until the wolves give up. Some studies have shown that when wolves hunt deer, an average of 84 to 87 out of every 100 deer escape. The ones caught are usually old, sick, or very young, rather than healthy animals in the prime of life.
After catching and killing their food, wolves may eat up to 20 percent of their body weight. That is like eating 80 quarter-pound hamburgers at one sitting! Wolves in the wild may not get to eat every day and must gorge when they get the chance.
Wolves also communicate by scent. Wolves mark the boundaries of their territories with their urine and feces and can smell these substances to determine just who left them there, and maybe even their age and gender. Wolves urinate on, or mark, things they regard as their property (such as food) and want to come back to later. Wolves can tell by scent whether female wolves are ready to mate. Wolves have many scent glands, including between their toes, and 1/4 of the way down the top of their tail (you can see the scent gland on the top of the tail as a dark spot part of the way down) to help spread their smell around.
Chorus howls may become rallies, where the howling wolves and sometimes the whole pack come together in a mob of wagging tails and sniffing noses. The wolves greet each other during a rally and act very excited. Lower-ranking wolves will often rally to higher-ranking wolves, directing their greeting behavior primarily toward the dominant animals and following them around as they howl, offering them submissive greetings and affirming their higher status. Sometimes rallies end in small arguments as the greeting ceremony brings two wolves who would rather not be near each other into close contact as they greet others in the group.
Contrary to popular belief, wolves do not howl at the full moon any more often than at any other time of the month. They also do not howl just at night. They do howl more frequently during the hours around sunrise and sunset, for they are more active in general than. Wolves also howl more often in the winter months than in the summer. However, they can be heard howling any time of day at any time of the year.
There are many subspecies of foxes, including gray foxes, fennec, arctic, and bat-eared. Red and gray foxes are the most common species seen in the United States. Gray foxes are smaller than reds, have oval pupils and black (rather than white) tail tips, and spend more time in trees. Their fur is also more gray than red, and their muzzles are smaller and more pointed.
The wolf (Canis lupus;[b] pl.: wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though gray wolves, as popularly understood, only comprise naturally-occurring wild subspecies. The wolf is the largest extant member of the family Canidae, and is further distinguished from other Canis species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The wolf's fur is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white.
Of all members of the genus Canis, the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanced expressive behaviour, including individual or group howling. It travels in nuclear families consisting of a mated pair accompanied by their offspring. Offspring may leave to form their own packs on the onset of sexual maturity and in response to competition for food within the pack. Wolves are also territorial, and fights over territory are among the principal causes of mortality. The wolf is mainly a carnivore and feeds on large wild hooved mammals as well as smaller animals, livestock, carrion, and garbage. Single wolves or mated pairs typically have higher success rates in hunting than do large packs. Pathogens and parasites, notably the rabies virus, may infect wolves.
The global wild wolf population was estimated to be 300,000 in 2003 and is considered to be of Least Concern by the International Union for Conservation of Nature (IUCN). Wolves have a long history of interactions with humans, having been despised and hunted in most pastoral communities because of their attacks on livestock, while conversely being respected in some agrarian and hunter-gatherer societies. Although the fear of wolves exists in many human societies, the majority of recorded attacks on people have been attributed to animals suffering from rabies. Wolf attacks on humans are rare because wolves are relatively few, live away from people, and have developed a fear of humans because of their experiences with hunters, farmers, ranchers, and shepherds.
The English "wolf" stems from the Old English wulf, which is itself thought to be derived from the Proto-Germanic *wulfaz. The Proto-Indo-European root *wĺ̥kʷos may also be the source of the Latin word for the animal lupus (*lkʷos).[5][6] The name "gray wolf" refers to the grayish colour of the species.[7]
In 1758, the Swedish botanist and zoologist Carl Linnaeus published in his Systema Naturae the binomial nomenclature.[4] Canis is the Latin word meaning "dog",[10] and under this genus he listed the doglike carnivores including domestic dogs, wolves, and jackals. He classified the domestic dog as Canis familiaris, and the wolf as Canis lupus.[4] Linnaeus considered the dog to be a separate species from the wolf because of its "cauda recurvata" (upturning tail) which is not found in any other canid.[11]
The phylogenetic descent of the extant wolf C. lupus from C. etruscus through C. mosbachensis is widely accepted.[15] The earliest fossils of C. lupus were found in what was once eastern Beringia at Old Crow, Yukon, Canada, and at Cripple Creek Sump, Fairbanks, Alaska. The age is not agreed upon but could date to one million years ago. Considerable morphological diversity existed among wolves by the Late Pleistocene. They had more robust skulls and teeth than modern wolves, often with a shortened snout, a pronounced development of the temporalis muscle, and robust premolars. It is proposed that these features were specialized adaptations for the processing of carcass and bone associated with the hunting and scavenging of Pleistocene megafauna. Compared with modern wolves, some Pleistocene wolves showed an increase in tooth breakage similar to that seen in the extinct dire wolf. This suggests they either often processed carcasses, or that they competed with other carnivores and needed to consume their prey quickly. Compared with those found in the modern spotted hyena, the frequency and location of tooth fractures in these wolves indicates they were habitual bone crackers.[16]
Genomic studies suggest modern wolves and dogs descend from a common ancestral wolf population[17][18][19] that existed 20,000 years ago.[17] A 2021 study found that the Himalayan wolf and the Indian plains wolf are part of a lineage that is basal to other wolves and split from them 200,000 years ago.[20] Other wolves appear to have originated in Beringia in an expansion that was driven by the huge ecological changes during the close of the Late Pleistocene.[21] A study in 2016 indicates that a population bottleneck was followed by a rapid radiation from an ancestral population at a time during, or just after, the Last Glacial Maximum. This implies the original morphologically diverse wolf populations were out-competed and replaced by more modern wolves.[22]
In the distant past, there was gene flow between African wolves, golden jackals, and gray wolves. The African wolf is a descendant of a genetically admixed canid of 72% wolf and 28% Ethiopian wolf ancestry. One African wolf from the Egyptian Sinai Peninsula showed admixture with Middle Eastern gray wolves and dogs.[24] There is evidence of gene flow between golden jackals and Middle Eastern wolves, less so with European and Asian wolves, and least with North American wolves. This indicates the golden jackal ancestry found in North American wolves may have occurred before the divergence of the Eurasian and North American wolves.[25]
In more recent times, some male Italian wolves originated from dog ancestry, which indicates female wolves will breed with male dogs in the wild.[27] In the Caucasus Mountains, ten percent of dogs including livestock guardian dogs, are first generation hybrids.[28] Although mating between golden jackals and wolves has never been observed, evidence of jackal-wolf hybridization was discovered through mitochondrial DNA analysis of jackals living in the Caucasus Mountains[28] and in Bulgaria.[29] In 2021, a genetic study found that the dog's similarity to the extant gray wolf was the result of substantial dog-into-wolf gene flow, with little evidence of the reverse.[30]
