[3] [4] In North America, on the basis of mean linear dimensions and body masses through the year, the smallest species appears to be the Alaska marmot and the largest is the Olympic marmot. [ 5 ] [ 7 ] [ 8 ] [ 6 ] Some species, such as the Himalayan marmot and Tarbagan marmot in Asia, appear to attain roughly similar body masses to the Olympic ...
The alpine marmot (Marmota marmota) is a large ground-dwelling squirrel, from the genus of marmots. It is found in high numbers in mountainous areas of central and southern Europe, [ 2 ] at heights between 800 and 3,200 m (2,600–10,500 ft) in the Alps , Carpathians , Tatras and Northern Apennines .
The tarbagan marmot (Marmota sibirica) is a species of rodent in the family Sciuridae.

In the past, it was a game animal, but in the 19th century, its population drastically declined. It is a herbivore active in the summer, living in territorial family clans in the mountains from the upper montane to the alpine zone.
The groundhog (Marmota monax), also known as the woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. [2] A lowland creature of North America, it is found through much of the Eastern United States , across Canada and into Alaska . [ 3 ]
A litter consists of five or six young but these stay in the family group for at least three years. The marmots congregate in larger groups to hibernate. The sleeping chamber has large quantities of bedding material and the entrances are plugged. [3] The black-capped marmot hibernates from September to mid-May. It is a diurnal and sedentary mammal.
The hoary marmot (Marmota caligata) is a species of marmot that inhabits the mountains of northwest North America.Hoary marmots live near the tree line on slopes with grasses and forbs to eat and rocky areas for cover.
David P. Barash reported that when hunting Olympic marmots as prey, coyotes and cougars approach the marmot within about 15 m (49 ft), advance to an alpine fir close to the victim, and then chase the marmot downhill to its colony. If the marmot is able to flee into a burrow and sound an alarm call, other marmots will scurry to their burrows for ...
