Wolf

 

The Biggest Animals Kingdom and in The World | Wolf | Gray Wolf slim, powerfully built animal with a large, deep chest and a downwardly sloping back. Legs moderately more wolf than other dogs. Women tend to have a narrow face and forehead, thin neck, a little shorter legs and narrower shoulders than men. In comparison with its smaller cousins (the coyote, and golden jackal), gray wolf bigger and heavier, with a broader snout, short ears, short body and long tail.The head is large and heavy gray wolf, with a broad forehead, strong jaws and long, blunt snout. Ears are relatively small and triangular. Wolf can be a devastating pressure lbf/in2 lbf/in2 1500 in comparison with 750 for the German Shepherd. In cold climates, the wolf, the blood supply to bring back to her skin to retain body heat.


Gray wolves usually has head at the same level as the rear lift only when a warning. IThis process may continue for several hours at a speed of 8-9 km / h and the wolf over long distances. On the bare road, a wolf can quickly reach speeds of 50-60 km / h. Powered Wolf keeps his head low and slightly to one side, sending one ear forward and one back. This position allows the wolf still use their exceptional hearing. hile a few loose wolves, most of them are very social animals. The basic social unit of the wolf pack is a linked pair, accompanied by an adult offspring pairs. The package consists of an average family of 11.5 animals (1-2 adults, 3-6 yearlings and 1-3 minors), and sometimes two or three such families, with an exceptionally large packages of 42 wolves fame.


Wolf grabs rarely take other wolves in his lap, and usually kill them. In times of abundance of ungulates (migration, calving, etc.), different wolf packs temporarily join forces. Wolves are very territorial animals, and generally much more territory than they need to survive, a steady stream of production. Wolf packs travel constantly in search of prey, is about 9% of the territory on the day (on average 25 km / day or 15 mi / g). The smallest area on record was on six pack of wolves in northeastern Minnesota, which takes approximately 33 km2 (13 square miles), while the largest was held by Alaska wolf pack of ten covers 6272 km2 (2422 square miles). Wolf packs are usually resolved, and usually only used to reach their leave during the acute food shortages. Wolves defend their territory from other packages by combining the scent of the markings of direct attacks and the first (see Contact).


When the scent marking and howling unable to keep the strange wolf packs of entering enemy territory, a violent interactions. Territorial fights are one of the leading causes of death of a wolf, a study on wolf mortality in Minnesota and Denali National Park and Preserve the conclusion that 14-65% of all deaths due to predation by other wolf wolves Gray wolves are typically monogamous, mating with a pair of generally stay together for life, as one of the pair dies. In the case of the death of a wolf pair covered quickly restored. Because men often prevails in some wolf populations, gypsy women are a rarity and spread male wolf can not establish a territory, or find a partner, he will work with the daughters of breeding pairs are created in other packages.


These wolves are "wolves Casanova" and, unlike the men of the installed packages, they do not form pair bonds with the women they mate with. Some wolf packs, several females, so, as is the case in Yellowstone National Park. Age at first breeding of wolves is highly dependent on environmental factors, when food is abundant, or where wolf populations are controlled, wolf pups to bring in a younger age in order to make better use of abundant resources. This shows once more the fact that the prisoner wolves are known to breed when they reach 9-10 months, while the young wolves recorded breeding in the wild was 2 years old. Unlike the coyote, the wolf never reach reproductive age.


The heat of the wolves only takes a month, do not abandon male wolves their friends, to find other women to fertilize as dogs do. During pregnancy, a woman in a den of wolves away from the peripheral zone of their territory, where violent clashes with other packages, is more likely. Wolves have a relatively large litters in small compared to other canid. The average litter consists of 5-6 pups, with throws tend to increase in areas where prey is abundant, but exceptionally large litter of pups 14-17 occur only 1% of the time. Puppies are born blind and deaf, and covered with short soft gray-brown fur. Puppies come from a den at 3 weeks. Puppies begin to eat solid food at age 3-4 weeks. Wolves use different sites for their daily entertainment: places with cover prefer the cold, wet and windy weather, while the wolves in a dry, warm weather is calm and out easily to relax. In


In rare cases, female wolves dig dens themselves, which are usually small and short, with 1-3 holes. Wolves are not the same location indicating probably a precaution against parasites. Because there are several convenient locations for holes, wolf teeth, usually occupied by the animals of the same family. In northern Montana, where wolves were heavily persecuted aerial hunters, the wolves have learned to avoid open spaces, when they heard the planes. On the other hand, biologists are using the aircraft was subjected to a study of wolves wolves are afraid that their approach, even when a low flying. When hunting, the wolves tend to focus on simple options at their disposal in areas populated by moose, and a small species of deer, the latter taking on a much larger share. Wolf described the powers of memory, George Mivart, who said that the wolf was able to hand his master to recognize, after three years absence.


Adult wolves are known to be cleverly hidden approaches to decide when their burrow, using bushes, fallen trees, stumps and other natural structures to hide their approach. Wolves experienced in the fall to learn how to avoid damage or even cause them, in his hunt for the wolf Currumpaw, naturalist Ernest Thompson Seton, noted that his first attempts to capture it were unsuccessful, as the wolf and count in the spring of the trap or ignore them. Although wolves are trained, they do not have the same degree of tractability seen in dogs. Wolves are more sensitive to positive conditioning and rewards, although simple praise is not enough, because in most dogs. In contrast to dogs, wolves tend to respond to hand than voice signals. Most attempts to prepare the wolves as a working dog failed.


Postural communication in wolves consists of different facial expressions, tail position and piloerection aggressive or overbearing wolves are characterized by a slow and deliberate movements, posture and high-raised feathers, and they are obedient to their body is low, to smooth their fur and the bottom of the ears and tail. Passive obedience usually occurs as a response to the approach of the dominant animal, and consists of a submissive wolf was lying partly on the back and the dominant wolf sniffing her anogenital region. The active view is often a form of greeting, and includes a submissive wolf approaches another in a low position, and licking the face of another wolf. If the wolves together, they tend to enjoy behavior, such as the nose, vibration, control of the jaw, cheek rubbing and licking her face. Dominant wolves may declare themselves to cross family member than subordinates. A wolf howls, as a rule, differ from those of large dogs.


Puppies are almost never cry, and the yearling wolf cry at the end of the production of a series of dog howl. A wolf howls can be heard, under certain conditions at a distance of up to 130 km2 (50 sq mi). When the howl with the wolves, not even on the same note in unison, creating the illusion of having more wolves than it is. Lone wolves generally avoid the curve in areas where other packages. Wolves did not respond to the cries in the rain, and when full.
