When we think about migration, we typically think of birds flying south for the winter, but actually other animals, in particular some species of caribou Rangifer tarandus, also migrate. Unlike birds, who are primarily avoiding harsh winter weather and temperatures, however, caribou migrate for a variety of reasons.

Do caribou migrate?
Like most herd animals, the caribou must keep moving to find adequate food. Large herds often migrate long distances (up to 400 miles/640 km) between summer and winter ranges. Smaller herds may not migrate at all.
Do caribou hibernate migrate or adapt?
The most important behavior caribou have adapted for survival is their annual migration from their summer range along the north coast to the boreal forests of the Richardson and Ogilvie mountain ranges.
Does the caribou hibernate?
Caribous do not go into hibernation during the winter, but if the weather conditions become very harsh than they will lower their metabolic rate and go into semi-hibernation. The Caribou has different diets for summer and winter.
Which season does caribou migrate?
The spring migration starts in early March and lasts until May as the caribou separate themselves into groups and migrate separately. The pregnant females and some yearlings, as well as the barren cows will start to migrate first, with the bulls following in their footsteps.
What triggers caribou to migrate?
First, the study found that caribou herds all across North America are triggered to start spring migration at roughly the same time by large-scale, ocean-driven climate cycles. Second, despite a synchronized start, arrival at their respective calving grounds depends on the previous summer’s weather conditions.
How often do caribou migrate?
Twice a year, caribou journey between their summer and winter range. A variety of factors influence the timing and route of migration. In a single year, most WAH caribou walk over 2,000 miles. One WAH caribou walked over 2,700 miles which is the longest recorded annual movement to date.
Why do caribou migrate in the winter?
One reason Caribou migrate is in order to reach remote birthing grounds. This is so that their newborn young are protected from predation from golden eagles, wolves, and grizzly bears during the calves’ most vulnerable early days.
How do caribou survive the winter?
In order to keep warm during the winter, caribou have two layers of insulating fur. This fur, while warm is completely hollow. Their buoyant hairs, wide hooves, and strong legs help them to swim as fast as 6 miles per hour.
Are caribou and reindeer the same?
Reindeer and caribou are the same animal (Rangifer tarandus) and are a member of the deer family. In Europe, they are called reindeer. In North America, the animals are called caribou if they are wild and reindeer if they are domesticated.
Why do the caribou leave their winter home to go north?
In northwest Alaska, caribou travel up to 2,737 miles (4,404 km) per year (Joly and Cameron 2017). One of the main purposes of migration is to minimize exposure to predation, especially during calving when young animals are particularly vulnerable (Fryxell and Sinclair 1988).
Why do caribou have two layers of fur?
They have two layers of fur to keep them extra warm (a tougher outer coat of hair as well as a soft and wooly undercoat). Their hair contains air pockets that helps to keep the animal warm and also makes them more buoyant while swimming.
How far do Alaskan caribou migrate?
Some herds of caribou migrate between 1,250 and 1,350 kilometers in Canada and Alaska each year to get from their wintering grounds to breeding grounds and back again.
Do reindeers migrate?
Migration. Caribou make one of the world’s great large-animal migrations. As summer approaches, they head north along well-trod annual routes. Some herds may travel more than 600 miles to get to their summer grazing grounds.
Do Elks migrate?
You might make the observation that elk are migratory creatures. They will migrate within their environment as nature dictates. Generally elk also migrate in similar patterns to the same areas year-to-year or season-to- season.
How many caribou migrate across the Arctic tundra?
The abundance of migratory herds of caribou (North America and Greenland) and wild reindeer (Russia and Norway) in circum-arctic tundra regions (Fig. 1) has declined 56% (4.7 million to 2.1 million) over the last two decades.
What is the difference between elk and caribou?
Elk and caribou are both members of the deer family and are herbivores. However, an adult elk is taller and weighs more than an adult caribou. When it comes to antlers, only male elk have them whereas antlers are found on both female and male caribou.
Are caribou predators or prey?
Because of their size and numbers, caribou are important prey species for most large predators of the arctic and subarctic habitats. Gray wolves (Canis lupus), grizzly bears (Ursus arctos) and black bears (Ursus americanus) will hunt and eat calves and sick or old adults.
How do caribou protect themselves?
Caribou protect themselves from predators, such as wolves, coyotes and bears, by spreading out over large areas of land.
What do caribou eat in winter?
Caribou feed mostly on grasses and plants in the summer and eat lichen and mushrooms during winter. Caribou feed mostly on grasses and plants in the summer and eat lichen and mushrooms during winter.
Do reindeers hibernate?
Deer don’t hibernate and sometimes group together to stay warm. Particularly cold winters sometimes kill deer outright, mainly by robbing them of food, especially when a hard layer of ice and snow keeps them from getting at food.
What do caribou use their antlers for?
Caribou (also known as reindeer) use their antlers to scrape away snow and soil to find food, as well as to defend themselves. Both male and female caribou have antlers, making them the only deer species in which females have antlers!
Are caribou endangered?
Are caribou and moose the same?
Moose are a lot bigger than caribou, capable of reaching double their weight and more. Also, moose are taller and longer than caribou. Moose antlers are large, flat, and wide but caribou have large, tall, branching antlers that are similar in many respects to deer.
Why do female deers not have antlers?
Females shed their antlers in May, just after their calves are born — but they begin to grow their antlers back later in the same month. That leaves a very narrow period of time in which female reindeer don’t have antlers, and it ensures that their antlers are at the fullest during the vulnerable months of pregnancy.
Where do caribou go when they migrate?
This “ecotype” of caribou migrates hundreds of miles each spring, moving toward the continent’s northern coast, where they birth their young. In contrast, woodland caribou live throughout the boreal forests and mountain ranges of North America.
Do caribou live in the tundra?
The caribou lives in the arctic tundra, mountain tundra, and northern forests of North America, Greenland, Scandinavia, and Russia.
Is a moose a reindeer?
is that reindeer is an arctic and subarctic-dwelling deer of the species rangifer tarandus , with a number of subspecies while moose is (us) the largest member of the deer family (alces alces ), of which the male has very large, palmate antlers or moose can be (obsolete|rare) a stew.
How many stomachs does a caribou have?
The Four Chambered Stomach
Caribou have a unique digestive system that includes four stomach compartments to digest their food; the rumen, reticulum, omasum, and abomasum. Of these, the rumen is the largest compartment, and it can hold many litres of food.
What’s a baby caribou called?
Animal | Baby Name |
---|---|
Caribou | calf or fawn |
Cat | kitten |
Cattle | calf |
Cheetah | cub |
Where do reindeer migrate to?
Eurasian and American forest reindeer live in family groups of 6 to 13, with seasonal ranges of 500 square km (190 square miles) or less. Tundra reindeer spend winter dispersed in forests but aggregate in spring to migrate onto the tundra; in fall they mass again to return to the forest.
Can reindeer fly?
A: Most reindeer can’t fly, but Santa’s reindeer are special. Because they’re magic, they can fly very high and very far without getting tired.
How do caribou sleep?
“Reindeer sleep in a series of naps, often associated with rumination,” Loudon wrote in an e-mail. “Since rumination cycles occur many times a day, the animal accumulates sleep but in many episodes.” The findings were surprising, but it is likely other Arctic animals also lack an internal clock, the researchers wrote.
Can elk and moose mate?
“No, that is not possible,” he says without hesitation. Although moose and elk are both deer species, the chances of the two reproducing are slim to none. “Elk and moose belong to different subfamilies of deer—genetically very far apart and totally incompatible.”
Where do elk migrate in winter?

Do moose migrate?
Now, thanks to GPS technology, it is firmly established that the Gustavus moose population is largely migratory with some animals traveling up to 30 kilometers between distinct winter and summer ranges. Not only do moose travel significant distances, but they travel to unusual places as well.
Why do caribou travel across the Arctic?
Caribou and reindeer migrations in the changing Arctic
In order to conserve large Rangifer populations, they must be allowed free passage along their migratory routes to reach seasonal ranges. We also provide some pragmatic ideas to help conserve Rangifer migrations into the future.
Does Colorado have caribou?
Are there Caribou in Colorado? A: Yes, one was found in Colorado in 2006 when sadly killed by a car in 2006, hundreds of miles from its normal range.
Can elk and caribou breed?
“They’re in completely different subfamilies of the deer family Cervidae. Elk can hybridize with sika deer, hog deer, and other species in the genus Cervus, but could never hybridize with caribou.”
What is caribou meat?
But unlike chicken, caribou is a red meat. This gives it a flavor and texture closer to beef, pork, bison, and other game animals like deer, elk, or moose.
Do polar bears eat caribou?
Researchers from the museum, Robert Rockwell and Linda Gormezano, found polar bears eat more caribou, snow geese and snow geese eggs because of lessening sea ice. That means polar bears might be able to cope with climate change, if they are switching from seal meat to other foods.
Do arctic foxes eat caribou?
These species feed on herbivores that are appropriately sized. For example, arctic foxes feed on lemmings, birds and carrion, Blue Planet Biomes states, while grey wolves, which are larger than foxes, hunt larger prey, including caribou, sheep and goats.
What is a male caribou called?
Male caribou are referred to as bulls. What are 3 facts about caribou? Both male and female caribou have antlers. From their noses to their hooves, reindeer are covered in fur.
What do caribou do in the winter?
In winter, Arctic caribou generally migrate south into the northern fringe of the boreal forest or onto tundra winter ranges where terrestrial lichens are abundant. Smaller mountain populations migrate out of the higher mountains onto the tundra and forest ranges adjacent to their mountainous summer ranges.
Do caribou eat other animals?
Summer Diet
Caribous are, for the most part, grazers. In the warmer summer months, however, caribous tend to dine on much broader assortments of sustenance.
Do caribou shed?
There are two annual molts, the main one between July and early September. During this period, the long worn coat of both guard hairs and undercoat is shed in great patches. Like most herd animals, caribou travel incessantly, moving among calving grounds, summer and winter range and breeding and fall range.
Do penguins hibernate?
Many species hibernate when the weather gets cold, curling up in a den to sleep away the winter. This helps them stay warm during the cold and lowers their metabolism to conserve food during months of scarcity. Emperor penguins living in Antarctica spend their lives in extreme cold.
Do bears hibernate?
Bears hibernate during the winter months in most areas of the world. Duration of winter denning is dependent upon latitude and varies from a few days or weeks for black bears in Mexico to 6 months or more for bears in Alaska (Kolenosky and Strathearn 1987, Haroldson et al. 2002).
Do moose hibernate?
I’ll start off simply and identify animals that don’t hibernate: deer, moose, hares, grouse, and voles and shrews under the snow. These animals don’t migrate and can find food all winter. Traditionally, hibernation has simply meant winter inactivity.
What animal eats lemmings?
All of the lemmings are staple prey for many larger animals which share their ranges, including weasels, arctic foxes, wolves, wolverines, weasels, mink, marten, snowy and short-eared owls, rough-legged hawks, peregrine falcons, glaucous gulls, and jaegers.
What animals eat caribou?
Foxes, ravens, owls,haegars and hawks are other carrion eaters or scavengers that feed on caribou kills. Native peoples have relied on caribou for centuries to supply them with the food they need to survive.
What colors can caribou see?
They only see the short (blue) and middle (green) wavelength colours. This means they can distinguish blue from red, but not green from red, or orange from red.
