Reindeer

“Travels more land space by foot annually than any other creature roaming the Earth”

The reindeer has become somewhat of a whimsical animal. Tales of ability to fly to pull Santa’s sleigh and other such stories have made them a fun focus for people both young and old. However, there is much to learn about these large animals that are found in the colder climates around the world.

Reindeer are one of the largest species of deer behind the caribou. These animals are known to cover as much as 3,100 square miles of land space during their travels throughout the year. Traveling in herds, the reindeer can be very protective of other members within their group. For the most part, the reindeer is a gentle and relaxed creature.
 

5 Amazing Reindeer Animal Facts

• Amazing eyes: Reindeers are the only mammals known to see ultraviolet light! This adaptation allows them to spot predators whose white fur is more visible in UV light.

• Natural air heaters: A reindeer has the ability to use their nose to warm the air they breathe in before it enters their lungs.

• Watch out for eagles: Golden eagles are one of the largest predators of reindeer calves when born.

• Yes, they’re fast: Reindeers can reach high speeds while sprinting. In fact, even at 24 hours of age, a newborn reindeer can outrun an Olympic sprinter!

• Reginald the red-nosed reindeer: The world’s most famous reindeer today is Santa’s trusty red-nosed reindeer Rudolph, but that wasn’t always his name! Rudolph first came from a 1930s coloring book from department story Montgomery world. Originally he was almost named Reginald and instead of having a glowing nose had glowing eyes!

From Animals to Rangifer: The Classification of Reindeer

Reindeers are classified as mammals that belong to the family Cevidae. In addition to reindeer, this family includes deer, brockets, elk, and pudu.

Rangifer Tarandus is the scientific name for reindeer. Rangifer is originally known as a small constellation found between the constellations of Cassiopeia and Camelopardalis. In Latin, both Rangifer and Tarandus mean reindeer with Rangifer being the generic name and Tarandus being the specific name.

Reindeer vs. Caribou

The name reindeer are called varies by their geography. In North America, reindeer are commonly called reindeer when domesticated and caribou when living freely in nature. In Europe, regardless of domestication, the species is called reindeer.

Domestication and hunting of reindeer are extremely important to many cultures across Arctic regions. For example, the Sami people of Finland’s Lapland region have long relied on reindeer for not only food, but also clothing and also travel needs.

Physical Features of the Reindeer

While there are different types of reindeer that can vary in size from one species to another, the common reindeer stand an average of 4 feet at the shoulders. These animals can grow to be six feet long. This is the same length as a twin-size bed.

The weight of a reindeer can range widely from one type to another. The average female reindeer weighs around 240 pounds, which is twice as heavy as an average octopus. A male has an average weight of 365 pounds, a little less than half the weight of a grizzly bear. However, it has been recorded that some reindeer can reach as much as 700 pounds. This is one-fifth the weight of an average car.

To protect them in the cold Arctic conditions in which they live, reindeer have thick fur that covers their entire body. This fur is made up of hollow hairs that allow for air to be trapped and heated to keep the reindeer warm. This insulated hollow hair also give the animal more buoyancy in the water to float when necessary. This feature makes river crossings much easier during migrations. Reindeer fur can be one of many shades of brown a light beige color. White patches are found on the chest, belly, neck and areas above the hooves.

The hooves of a reindeer are useful tools that are important for their survival. The hooves are wide in size. In the winter the hooves are hard, allowing the reindeer to cut into the snow and ice for traction. In warmer season the hooves of the reindeer become softer and allow for easier swimming and gripping in the mud. There is a distinguishable sound created when the tendons rub across the bone of the hooves.

Reindeer Antlers

Both male and female reindeer grow antlers. However, male reindeer antlers tend to be twice as big in size. The velvet surrounding the male’s antlers tends to fall off in late August. They shed their antlers following the Fall rut which occurs at the end of October or November. Females don’t tend to shed their antlers until Spring.

Behaviors of the Reindeer

Reindeer can run up to 50 miles per hour! Beyond being fast sprinters, reindeer are also migration champions. The animals are known to travel more than 3,100 miles in a single year – the same length as the self-transcendance race, the world’s longest certified footrace. 

The reindeer travel in large packs that can contain tens of thousands of animals at any given time during the summer months. These groups are known as a herd. Scientists believe that this provides relief from mosquitoes, warble flies, and nose bot flies that can become bothersome to the reindeer. When the weather begins to cool off, the herd starts thinning out. During this time the herds can dwindle to as little as having just ten members at a time. This often occurs during the rut season that takes place in the fall. It is also the time when breeding most often occurs in the herd.
 

Reindeer Habitat

You will find the reindeer living in polar and Arctic climates. Most reindeer are found in the northern hemisphere. Herds have been spotted in Europe, Asia and North America. The animals prefers forests as these spaces are filled with the food resources that the animal needs for survival. The thick cover of trees such as pines, spruce and other conifer trees give the reindeer places to bed down. These trees offer some protection from the weather elements and from being easily spotted by predators.
 

Location of Reindeer Subspecies Around the World

There are six main subspecies (sometimes called reindeer breeds) of the reindeer known to roam the Earth today. These include the following:

• Svalbard reindeer – Found in the Svalbard archipelago of Norway, this is the smallest subspecies of the reindeer recorded.

• Finnish forest reindeer – This subspecies of the reindeer is rare and classified as being a threatened breed. The Finish forest reindeer are common in Russian Karelia and provinces including North Karelia, Kainuu, and Savonia in central south Finland.

• Boreal Woodland caribou – More commonly known as the Woodland caribou, the Boreal Woodland caribou live in the forests of Canada and North America.

• Barren-ground caribou – This subspecies of the reindeer includes the Porcupine caribou as well. These animals are found throughout the Canadian territories including Nanavut and the Northwest Territories. There have been recordings of the barren-ground caribou roaming throughout Kitaa, Greenland as well.

• Eurasian Tundra reindeer – Also known as the mountain reindeer, this subspecies of the reindeer can be found enjoying the atmosphere of western Scandinavian Peninsula. You will find the majority of these herds located in Norway.

• Peary caribou – The smallest of the North American caribou, these reindeer relatives live in the High Arctic Island of Nanavut as well as the Northwest Territories of Canada.

Reindeer Diet

Classified as herbivores, reindeer live on diets of plants and vegetation.

What do reindeer eat?

Some of the favorite foods of the reindeer include willow and birch leaves, mushrooms, sedges, cotton grass, and ground dwelling vegetation. The animals do enjoy fruits and berries when available. However, while these foods are okay as a treat, eating them in abundance is not healthy for the reindeer.

During colder seasons when plants and vegetation are limited, reindeer use their keen sense of smell to locate lichen under the snow. Using their hard hooves to break through the snow and ice covering, the animals are able to access this food. Cows will use their antlers in these situations to help gain access to the lichen. On average, a reindeer will consume between 9-18 pounds of food every day.

While it not their first choice in food, reindeer have been known to eat small rodents on ocassion. This gives them the ability to sustain their nutritional needs and fulfill the need for protein and iron in their diets.
 

Predators and Threats of the Reindeer

Living in the wild, reindeer face the threat of different types of predators.

What eats reindeer?

The most common animals that prey on the reindeer include wolves, golden eagles, and bear. However, when killed, other carnivorous animals will consume the meat of the reindeer.

Humans are among one of the biggest predators of the reindeer. They hunt the animals for the meat, hides and fur. The fur is used to create warm clothing for extreme cold weather conditions. The hides are tanned. This creates a waterproof leather material that is ideal for making shoes, tents and clothing.

While domesticated reindeer don’t often worry about predators as being a threat to their livelihood, there are other types of threats that they face. Most reindeer kept in captivity are not provided with the proper type of environment to sustain their type of lifestyle. This can cause the animals to die due to depression, disease and even starvation when the right types of food are not provided.
 

Reindeer Reproduction and Life Cycles

Breeding season for the reindeer takes place from early October until the end of November. This is known as the Fall rut. The male selects 5-15 females from the herd during breeding season to create a harem. To prepare for this annual event, the male will rub the velvet from their antlers. Their body begins to increase in size with the neck swelling and a mane of hair forming under their neck.

The total gestation period for a reindeer pregnancy is 228-234 days. To prepare for the birth of their babies, the cows leave their herd and travel to a common calving ground in the Spring. It is common for the mothers to give birth to one calf at a time. There are rare instances in which twins are born to the mother. This is the only litter the female reindeer will have for the year.

Calves suckle for the first week of their life. Solid foods are added to their diet after this period. By two weeks of age, the babies most often double their birth weight. Weaning begins for the baby at about six months of age. However, the babies will stay with their mother for the first year. The average life expectancy for the reindeer living in the wild is 15 years. This duration of time is even less for domesticated animals as they lack the same stimulation as what is found in their natural habitats.
 

Reindeer Population

There are 2.1 million reported reindeer and caribou herds that live in different regions around the world. This is less than half of the population reported in 1996. At that time researchers estimate that 4.7 million herds roaming the Earth.

The decline in population has many causes. For one, the environments in which the reindeer depend of for shelter and food are diminishing with ongoing human development. Increases in wolf and bear populations also creates more of a threat to the animals. Lastly, human hunting for furs continues to be a threat to these anmals.

Reindeer Animals vs. Reindeer in Pop Culture

Reindeer have become extremely iconic in pop culture thanks to their association with Santa Claus and Christmas folklore.

Rudolph the Red-Nosed Reindeer first appeared in a Montgomery Ward catalog in 1939. The character was originally conceived as “Reginald,” a reindeer with glowing red eyes that could guide Santa’s sleigh, but was later changed to “Rudolph” before publication. The popularity of Rudolph and the association of reindeer with Santa Claus reached new heights after a stop-motion film in 1964.
