Moose, reindeer and deer, large herbivorous mammals in the boreal forests of Canada

Canada's boreal forests are home to a number of large herbivorous mammals such as moose, reindeer or caribou and deer. Zootechnical are ranked low in the same order: Artiodactyla (toed ungulates), Family: Cervidae (deer).
These herbivores are the legendary survivors with greater adaptability that today live in this snowy land. Also symbolize the peace and harmony with nature.
Below is a brief fact sheet on these distinguished and admired Canadians.
Moose: They are hardy animals and heavy with a big massive head and a long nose. The average weight for males is 430 kg and 350 kg in females have short tails, a hump in the front room and large ears that rotate. Adult males have a long and flexible jowls hanging below the throat, whose function is unknown, and develop a huge antlers each summer move on. The elk can cross deep snow with their long legs, which are protected against inclement weather by a thick layer formed from hollow hairs. They have very good sense of smell and hearing but his vision is not the best. They can eat up to 20 pounds of plants each day and come to migrate with the seasons in search of fresh vegetation. North America's total population is between 800,000 and 1.2 million animals. Hunters hunt about 90,000 moose a year. His only other predators are bears and wolves.
Reindeer or caribou: Are the only species of deer in which females and males have antlers shaped chandelier. The average weight for males is 110 kg and 81 kg in females live in large migratory herds along the tree line of northern forests, feeding mainly herbs and shrubs in the summer; and lichens that cover the forest floor during winter. To feed during the winter snow must dig hard to compete with other reindeer. This may explain why females have antlers too. During the mating season, males compete for females facing horns. It is so much attention to the mating rituals that many forget even to eat, lose too much energy in this process. Females give birth in the boreal forest plains in the spring after a gestation period of 7 months. Then put all their energy reserves to feed their babies for a month. There are over 2 million caribou in North America, but are less successful in the southern part of their range where they deal with humans and other predators.
Deer Represent a population of about 750,000 and live in federally protected areas in the United States and Canada. The average weight for males is 331 kg and females 241 kg have prospered due to good conservation and management practices and also due to the decline of large predators. Flocks may include more than 200 animals. Males and females often congregate in separate herds until the breeding season in late September or early October. At this time adult males show a variety of flamboyant behaviour to excel and compete for fertile females. They use their large six-pointed antlers that can measure six feet, to cope with other males, roar with strength and spread urine. A fawn weighs about 14 pounds and born after a gestation period of six months. The future of the deer seems assured as long as they remain balanced the interests of hunters, farmers and tourists.
