“Marmots make a whistling sound to alert others around them of a predator in the area”

A marmot animal is a rodent of medium size with brown fur on its head and back as well as yellow fur on its belly. This animal is a herbivore eating nuts, leaves, seeds, flowers, grass, and grains. They live in Europe, Asia, and North America. Groups of marmots are called colonies. Marmots are animals that can live from 13 to 15 years in the wild.

5 Incredible Marmot Animal Facts!

  • This rodent is sometimes called a whistle pig
  • These animals spend time sunning themselves on rocks to get warm
  • A marmot’s territory can sometimes include 7 acres of land
  • Marmots aren’t able to see very far in front of them
  • The burrow system of their colony has several entrances and exits

The yellow-bellied marmot’s animal scientific name is Marmota flaviventris. The word Marmota is Latin for mountain mouse and the word flaviventris translates to yellow-bellied. It goes by several other names including whistle pig, groundhog, ground squirrel, and rock chuck.

This animal belongs to the Sciuridae family and the class Mammalia.


Marmots belong to the larger family of ground squirrels collectively referred to as Marmotini. While no one can quite agree as to their origins, it is worth noting that the very oldest fossils date back to more than 30 million years ago, during the Early Oligocene.

By the late Oligocene, early versions of chipmunks and marmots were known to exist in North America giving rise to the belief that genetic divergence had occurred by the middle of the era. By the mid-Miocene, prairie dogs and susliks had emerged on the scene and occupied a range similar to that covered by their present-day descendants, as proven by fossil evidence.

There are 15 species of this ground squirrel. They include:

  • Alpine marmot (Marmota marmota): Believed to be the tubbiest of this subfamily, it is capable of weighing approximately 18 lbs and measuring 30 inches. The chubby rodent can be found in the mountains of Central and Southern Europe. There it lives at elevations between 2,600 – 10,500 feet and appears to be doing rather well for itself, population-wise. 
  • Alaska marmot (Marmota broweri): Recognizable by its gray coat and preference for living in large families,  these rotund mammals are fond of water and tend to settle close to lakes. 
  • Black-capped marmot (Marmota camtschatica): Found in Siberia, these rodents are capable of growing to 2 feet in length and weighing 12 lbs. They can also live at different elevations and have even been found as high as 6,000 feet.
  • Forest-steppe marmot (Marmota kastschenkoi): Named for its forest-steppe habitat, this marmot has a weight range of 6.6 – 20 lbs. It also hibernates for half a year and can be found in southeastern Russia.
  • Long-tailed marmot (Marmota caudata): Generally found in central Asia, this chubby rodent generally weighs between 16 – 20 lbs. Also known as the golden marmot, it is known for having a tail capable of growing to 11 inches which is longer than those of its other close relatives.

Appearance & Behavior

Yellow-bellied marmots have short brown fur on their back and heads along with yellow fur on their bellies. They have small ears, a black nose, and claws strong enough to dig deep burrows. In terms of size, these rodents measure 18.5 inches to 27.5 inches in length. Its bushy tail can measure up to 8 inches long. This rodent spins and lifts its tail as it runs. The weight range for this animal goes from 3.5 lbs to 24 lbs. Thirteen golf tees lined up end to end on the ground would equal the length of a 27-inch long animal. Alternatively, an 11-pound marmot is equal in weight to a gallon can of paint.

The largest species is the Olympic marmot animal. This animal can weigh up to 18 pounds. Though this animal isn’t a pet, it’s almost as heavy as an adult dachshund!

One of the defensive features of this animal is its voice. One marmot animal ‘stands guard’ over a colony while they look for food above ground. If it spots a predator, it makes a loud whistling sound. When other animals hear this, they run into their burrows and tunnels to escape danger. They make other sounds such as chattering and clicking. They even have a sound that is similar to a scream. All of these sounds are a unique form of communication between these ground squirrels.

Marmots are animals that make their homes in small spaces or in areas that are hard to access. This could be a crevice in a rock or a burrow beneath a collection of boulders. Many of their predators can’t gain access to these burrows and tunnels. This is another way they can escape an enemy or stay out of sight while scanning the area.

These animals are active during the day. Many of them lay on rocks sunning themselves in the morning, then look for food. Most of them are social animals and live in colonies with 10 to 20 other animals. However, some species live by themselves or with just one other marmot. This is a shy animal with a lot of predators. It prefers to stay underground and out of sight most of the time.


Amazing Mountain Animal: Himalayan Marmot

These animals live in Asia, Europe, and North America. These animals make their homes in mountainous areas, meadows, tundras, forest edges, grasslands, and steppes.

The Himalayan marmot lives in mountains in Nepal as well as in India and Tibet. Alpine marmots live in the Alps, Carpathians, Pyrenees, and other mountain ranges in Europe. The long-tailed marmot lives in Central Asia in the Tien Shen mountains.

In North America, the yellow-bellied marmot lives in the Rocky Mountains, Sierra Nevada, and other places in the western part of the U.S. The Olympic marmot lives in Washington State.

The yellow-bellied marmot lives in a climate that’s dry and warm. Alternatively, the Alpine marmot that lives in the Alps is able to live in a very cold climate. In fact, this animal hibernates for about 9 months each year. Their strong claws allow them to dig in the partially frozen ground to expand their burrow system in preparation for hibernation.

Hibernation is how these animals deal with the freezing winter temperatures of their habitat. They eat a lot during the summer to store fat in order to survive hibernation which begins in September and ends in May. During hibernation, the animals huddle together in a burrow for warmth. Interestingly, a marmot takes just 2 to 3 breaths per minute while in full hibernation mode.

Some of these animals migrate from the location of their winter dens to their summer dens. They dig winter dens at a lower altitude than their summer dens.

Males are territorial. They mark their territory with scent to warn other animals away from the area. Marmot animals from the same colony get along fairly well. But, if an animal from another colony enters a strange burrow, there can be fights between the males. They chase and fiercely bite one another over territory.

Predators and Threats

What eats marmots?

This ground squirrel has several predators including coyotes, foxes, eagles, and badgers. Sometimes coyotes and foxes look for their burrows so they can capture these animals when they come out to look for food. Eagles can swoop down with speed and focus to capture them venturing outside of their tunnels to eat.

Babies are vulnerable to these predators as well. They must come out of the burrow to learn how to find plants, leaves, and other food.

What do marmots eat?

What Do Marmots Eat
Although marmots enjoy herbivorous fare, they are also partial to insects and even bird eggs, too

These animals are herbivores eating flowers, nuts, grains, and plants. They eat what’s most plentiful in their habitat during the spring and summer.

Alpine marmot animals can eat plants in their environment that would be poisonous to other mammals. This is true for other sorts of rodents as well.

These rodents weigh more in the fall season than they do in the spring. This is because they eat a lot over the summer to store fat they can live on while hibernating over 9 months. An animal may gain 4 or 5 pounds in preparation for hibernation. When it comes out in the spring, it weighs less having used up the stored fat.

Fortunately, the yellow-bellied marmot along with many other species of this animal doesn’t face any major threats. Sometimes Alpine marmots are hunted for sport as well as for food. There’s also a belief that their fat also known as “mankei” fat is a cure for arthritis. So, these rodents are sometimes captured for this purpose.

The conservation status of the yellow-bellied marmot along with most others is Least Concern with a stable population.

Reproduction and Life Cycle

The breeding season of the yellow-bellied marmot takes place from May to June. These animals breed just once per year. Olympic marmots breed every other year.

Male marmots mate with several females during this time. This breeding system is called harem polygynous. A male mates with several females and defends them from other male marmots.

The gestation period of a female marmot animal is approximately 30 days. They can have a litter of 3 to 8 babies also known as pups. But, on average, they give live birth to 4 pups. The pups are born with their eyes closed and without any fur. Each newborn pup weighs just one ounce.

The mother nurses her pups for about three weeks, then begins to feed them grasses and plants. The pups begin to venture out of the burrow to explore and look for food at around 4 weeks old. They are fully weaned at 7 weeks of age. Though the female continues to take some care of the pups, they are growing quickly and becoming more self-sufficient. Marmot pups are completely independent at 7 weeks old, but they may remain a member of the colony. In some cases, the parents of 7-week-old pups will chase them away from the colony forcing them to find a new system of burrows to live in.

Marmot pups are sexually mature at about 2 years old. The lifespan of a marmot is 13-15 years. These animals are vulnerable to a variety of intestinal parasites.

The exact population of the yellow-bellied marmot is unknown. But its conservation status is Least Concern, and it has a stable population.
The population of the Alpine marmot is estimated at over 100,000 with 1,500 living in the Carpathian Mountains.

Fortunately, there are many national parks in the United States where marmots live in abundance. There’s Rocky Mountain National Park in Colorado, Sequoia & Kings Canyon in California, Olympic National Park in Washington State, and Denali National Park and Reserve in Alaska just to name a few!
