Wolf

True Wild Life | Wolf | The wolf is thought to be an ice age survivor, dating wolves around 300,000 years ago. The wolf is accepted to be the ancestor of the domestic dog as the wolf is thought to have selectively bred in order to breed appealing traits typical of puppies and to eliminate the not so appealing traits of adult wolves. The grey wolf is a highly adaptive animal found in all kinds of terrain. Wolves inhabit forests, deserts, mountains, tundras, grasslands and even urban areas with the wolf being a particularly dominant and ruthless predator within it's environment. They vary in color from pure white to pure black and every shade of brown and gray inbetween. At one time the wolf had the widest distribution of any mammal. The biggest wolves on earth live in Alaska and average 125-135 lb. One specimen was taken that weighed 200 lb. The smallest wolves live in Iran and average about 60 lb.

The wolf lives to be approximately 10 years old in the wild. Wolves live in packs that generally consist of the alpha male wolf, his mate the alpha female, and their offspring of various ages. Other wolves may also join, but it is the parents that are the leaders. The wolf has no real natural predators; their biggest threat is other wolf packs on adjacent territories. The wolf has been known to live up to 20 years old in captivity. Wolves are carnivorous animals and generally hunt large animals but wolves will also hunt smaller animals if they are need of their daily meal. Wolves hunt together in their packs and work together as a team in order to catch and kill a large animal such as moose and deer. Wolves are opportunists and will not waste their energy chasing a healthy deer 10 miles when an injured or sick one is available. The native Alaskan peoples call the wolf the "wild shepherd of the caribou".

Wolves have a layer of thick fur which is particularly needed for those wolves that inhabit areas of the Arctic circle where it can be extremely cold. It is during the winter months in these areas that calories are most critical . Larger animals such as elk and deer suffer greatly from the cold and lack of food to eat and it is during this time that the prey of the wolf is at its slowest and therefore is easier to catch. Wolves are considered to be an endangered species today as wolves have been widely exterminated from their former ranges by hunting, poisoning, and trapping to procure their fur and to protect livestock. Wolves have also been severely affected by habitat loss and have been pushed into smaller and smaller territories where the food source may not be plentiful enough to sustain a hungry wolf pack and where heavy inbreeding occurs.

Wolves tend to mate in late winter to early spring and the wolf cubs are born are born a couple of months later when the weather is warmer and prey is abundant. The wolf cubs then have the rest of the year to grow stronger in order to be able to survive their first cold winter. Wolf cubs stay with their mother in the wolf pack with the male wolf cubs often leaving to form a pack of their own. Wolves can interbreed freely with dogs, redwolves, coyotes, and jackals to produce fertile offspring. This is a case of incomplete speciation. There are physical, behavioral, and ecological differences between these species, but they are fully genetically compatible. None of the animals in this group can breed with foxes, which are too far separated genetically.

Arctic Wolf

True Wild Life | Arctic Wolf | The Arctic wolf is found in the most northern parts of the wolf's range, in the Arctic Circle. Arctic wolves mainly inhabit Northern Canada and Alaska, parts of Greenland and Iceland and Northern Europe. Arctic wolves are incredibly versatile and adaptive animals, able to withstand year round sub-zero temperatures. Living in the Arctic Circle, the Arctic wolf spends five out of twelve months in total darkness.

The Arctic wolf hunts lemmings, assorted rodents, and Arctic hare but will take larger prey like caribou when available. When the Arctic wolf wants to hunt musk ox, the pack will gather and work as a team attempt to isolate it from the herd and take it. An adult musk ox is simply too big for one Arctic wolf to try and take on alone. Although the Arctic wolf is generally smaller in size than the grey wolf, Arctic wolves tend to be bulkier than grey wolves with the male Arctic wolves also growing larger than the female Arctic wolves.

Normally, only the alpha male Arctic wolf and female Arctic wolves breed, but if a pack gets too large it may break up into new smaller packs giving others the opportunity to mate. Due to the Arctic Circle's uncompromising permafrost soil and the difficulty it poses for digging dens, Arctic wolves often use rock outcroppings, caves or even shallow depressions as dens instead.

Arctic wolf pups are born in litters of two or three in the months of May and June, meaning that the Arctic wolf pups are born about a month later than the grey wolf pups. Arctic wolves tend to be white with brown irises, unlike most other subspecies of wolves with yellow to amber eyes. White fur gives them camouflage in a snowy environment, and the darker irises give added protection to the eyes in a high glare environment.

Red Wolf

 

True Wild Life | Red Wolf |  The red wolf was roamed across the south-eastern United States from Texas to Florida to New York. The red wolf's historical habitat included areas of forest, swampland and coastal prairies where it would of been one of the top predators. Today however, the world's red wolf population is confined to a protected area in North Carolina. The red wolf is a medium sized species of wolf, found in the coastal marshlands of southern parts of eastern North America. By the 1970s the pure red wolf was thought to be extinct in the wild, but a population has since been reintroduced in North Carolina that is said to now be up to 100 red wolf individuals.

 

The red wolf is generally smaller in size than the grey wolf, found in more northern parts of North America. Red wolves are named for their cinnamon coloured fur, which is brownish-red with dark patches on their backs. Red wolves also have broad noses and large looking ears for the size of their head. In a similar way to other canines, and indeed other wolf species, the red wolf is a very sociable animal, living in pack with a number of other red wolf individuals. Red wolf packs usually contain a dominant male and female and their offspring and contain between 2 and 10 members. The red wolf is also a highly territorial animal, with the red wolf pack guarding it's range from intrusion by other red wolf packs in the area.

Although red wolves are known to hunt together as a group in order to catch a larger animal such as a deer, red wolves primarily eat smaller ground dwelling animals such as rabbits and rodents. Red wolves also eat birds, raccoons and other small animals. When trying to hunt a larger animal, the red wolf pack works together to confuse and corner their prey. In their historical range, red wolves were considered to be one of the most dominant predators within their environment, only coming under threat from larger canines such as grey wolves or the occasional coyote. Human hunters wiped out the red wolf population in large parts of their natural range, and the population was finally thought to become extinct primarily due to habitat loss.

Red wolves are usually able to reproduce by the time they are 2 years old and begin mating in the warmer spring months of February and March. The female red wolf gives birth to a litter of up to 10 cubs after a gestation period that lasts for around 60 days. Cubs are born blind and are nursed by the rest of the pack until they are able to hunt for themselves and either remain with their parents or leave to start a pack of their own. Today, the red wolf is no longer extinct in the wild since their reintroduction to North Carolina in 1987, and the population their is now thought to be just over 100 red wolf individuals. Nevertheless, the red wolf is still considered to be a critically endangered animal and is regarded as the 10th most endangered animal species in the world.
