The Caribou, also called caribou in North America, a beautiful species of large deer with seasonal distribution, mostly resident in sub-Arctic, tundra and boreal regions of north, central, and South America. This includes both migratory and sedentary populations. They have adapted to a variety of habitats and are able to survive in cold conditions both in the air and on land. In fact, they have adapted well to their arctic habitat. They are nocturnal animals, which means they sleep and lie down almost all the time.
These animals are omnivores, eating plants and animals along with meat. Their range typically covers a vast area of mountain ranges and plains. In wintertime, they migrate to higher areas to find food and a protected place to rest. When spring comes, they begin their migration back to the southern latitudes. For most animals, the wintertime is the warm season because animals feed at this time.
Although they have evolved in a wide range of habitats, including forests, tundra and mountainous, they are primarily found in borealis or sub-tropical environments. In borealis, they feed near water and in sub-tropical areas they often feed near water Caribou. Caribou in tundra and mountain regions have thicker hair, indicating that they usually feed near water. In arctic zones, the animals also eat a diet consisting mainly of plants. In warm seasons, animals also eat grasses, but unlike herbivores, they prefer insects, roots, tubers and berries over the grains.
During the warm season, the animals help regulate their body temperature by using body heat and sweating. They also help regulate their metabolism by consuming a lot of food and burning even more during wintertime. In warm seasons, they help keep their body temperatures normal because they control metabolism and body temperature with the help of air currents and body heat. During winter, the animals stop using these methods to regulate body temperature because the snow reduces their body temperature.
Caribou in the arctic zone have adapted to survive in the coldest part of the year. This is why they inhabit the far north in relatively warm areas like the arctic tundra. Unlike the polar bears, who travel southwards in the arctic winter, the Caribou makes an annual journey southwards through the boreal forests. During this journey, they spend the winter on the tundra. The migration takes about two weeks. And in the spring, they enter the semi-desert in search of green pastures and water.
In spite of their long journey in the arctic winter, animals emerge from the arctic zone ready to take part in the annual breeding activities. They give birth to young calves that are born in late spring and early summer. These young bears spend the first two months of the year on their mother’s milk, which nourishes them up until they gain muscle mass and strength. They gain weight in the months of June and July, when they start to forage on plant leaves and grass. They become larger in September and October, when they head for the open waters of the Arctic Ocean.
