This action helps reduce some of the energy costs associated with hibernating. Because they hibernate for 8 months from September to May, they actually spend about 80% of their lives underground. at http://web.ebscohost.com/ehost/pdfviewer/pdfviewer?hid=113&sid=d0bb74af-5002-40cc-acc3-d8f2b6e902d3%40sessionmgr115&vid=3. This gives each colony member a chance to escape into the nearest burrow entrance. Yellow-bellied marmots usually weigh from 1.6–5.2 kg (3 lb 8 oz–11 lb 7 oz) when fully grown, though males typically weigh more than females. Their hibernation period varies on elevation, but it is typically from September to May. A marmot is very able to create havoc for gardeners because of their love of plants. February 23, 2011 (Blumstein, et al., 2004; Frase and Hoffmann, 1980; Wey and Blumstein, 2010), Yellow-bellied marmots have one breeding season per year right after they wake up from hibernating for the winter. Their burrows are used by other kinds of digging animals after they leave. They are impacted by predators, who cause 98% of their deaths in the summer. They are 1 of only 2 species of marmots that don't hibernate in social groups. All rights reserved. [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. Young are also weaned and start eating solid foods, again mostly leaves, fruit and seeds in late summer. (Blumstein, et al., 2004; Frase and Hoffmann, 1980; Wey and Blumstein, 2010). Reasons Dogs Eat Poop Coprophagia Disgusting Animal Habits getting Dogs to Quit Eating Poop. Other animals like American pikas and golden-mantled ground squirrels might respond to alarm calls of yellow-bellied marmots. They are the heaviest members of the squirrel family. [9][10] In the traditional definition of hibernation, the largest marmots are considered the largest "true hibernators" (since larger "hibernators" such as bears do not have the same physiological characteristics as obligate hibernating animals such as assorted rodents, bats and insectivores).[11][12]. Upon seeing a predator, the yellow-bellied marmot whistles to warn the others in the area,[5][a] after which it typically hides in a nearby rock pile until there is no more threat . Through winter, the Information Office is open 8:00 am–4:30 pm Mon–Fri.

[20], Beginning in 2010, Alaska celebrates February 2 as "Marmot Day", a holiday intended to observe the prevalence of marmots in that state and take the place of Groundhog Day. [7] Each male marmot digs a burrow soon after it wakes from hibernation, and starts looking for females to reproduce. Accessed Marmots eat green plants and can become pests in vegetable gardens. [6] In food choice experiments, yellow-bellied marmots are known to reject plants containing defensive compounds. Stefanie Hwang (author), The College of New Jersey, Matthew Wund (editor), The College of New Jersey, John Berini (editor), Animal Diversity Web Staff, Catherine Kent (editor), Special Projects. Accessed [14] They divide marmots into two subgenera. Marmots typically live in burrows (often within rockpiles, particularly in the case of the yellow-bellied marmot), and hibernate there through the winter. The two species overlap in a small part of northwestern Montana and western Washington. Marmot Lawn Damage. Females weigh 1.59 to 3.57 kg, and usually about 2.8 kg. (Frase and Hoffmann, 1980), Yellow-bellied marmots normally come out from their burrows in the early morning, and spend time grooming themselves and laying in the sun. Different subspecies have different colors. 2: 378-387. (Frase and Hoffmann, 1980), Yellow-bellied marmots live in many parts of the western United States and Canada. Although most marmots are monogamous, in some species, females have multiple mates. Mating occurs in spring when they emerge from hibernation, and litter sizes average three to eight pups per female. "Family Sciuridae". It may have arisen from the Gallo-Romance prefix marm-, meaning to mumble or murmur (an example of onomatopoeia). Then, they lay in the sun more, groom themselves, and spend time in the burrow. The size of the burrow allows the animal to not only eat while underground, if necessary, it also lets them store food underground for later use. Rocks support their burrows and give them spaces to sun themselves and be on lookout. (Frase and Hoffmann, 1980), Males are longer than females and quite a bit heavier. In the wild, they can be worthy of observation and preservation, though area farmers might feel considerably different-minded. Peissel, Michel. Still, it isn’t what and how they eat that cause marmots to be on a farmer’s or gardener’s list of troublesome pests. Their back feet are 70 to 90 mm long, and their heads are 68.0 to 99.8 mm long.

[5] Northwards, its range extends into the southern British Columbia and goes eastwards up to the montane and basin regions of Wyoming, eastern Montana, Colorado, and southern Alberta. They are all closely related to hoary marmots. Yellow-bellied marmots scream when excited or scared. The 3 most important noises they make are called: the whistle, the undulating scream, and the tooth chatter. Early in the spring when plants start to grow again after a winter rest, marmots emerge from their burrows hungry. 1: 132-138. The marmot holes can be dangerous for hikers or animals like horses, and if the tunnels cut into a river or canal bank, it doesn’t take much for flooding to occur. An anatomically accurate image of a marmot was printed and distributed as early as 1605 by Jacopo Ligozzi, who was noted for his images of flora and fauna. This hungry plant eater loves to feast on grasses, flowers, seeds and nuts – so gardens and yards provide an ample feeding ground for this gluttonous rodent. Their bodies are covered in coarse hair that is lighter on the tips and darker at the base. There are many species; however, the common names for them often relate to the areas they are most often found, even if the species is actually the same. [1], Marmots are large rodents with characteristically short but robust legs, enlarged claws well adapted to digging, stout bodies, and large heads and incisors to quickly process a variety of vegetation. February 23, 2011 Journal of Zoology, v. 270 no. And sometimes they will whistle about it. [5], Yellow-bellied marmots are diurnal, and are less active during the night. "Family Sciuridae". (2005). [4][5][6] The largest and smallest species are not clearly known. Their large body size is an adaptation to the cold, high elevation sites in which they live. When above ground, marmots spend much of their time fattening up and resting in the sunshine during the short growing season. Yellow-bellied marmots have small, furry ears. 1980. Across all places, they are usually found around 2,000 m in elevation. Friendly behaviors are playing, grooming, and greeting each other. Research by the French ethnologist Michel Peissel claimed the story of the "Gold-digging ant" reported by the Ancient Greek historian Herodotus, who lived in the fifth century BCE, was founded on the golden Himalayan marmot of the Deosai Plateau and the habit of local tribes such as the Brokpa to collect the gold dust excavated from their burrows.[19]. There are 6 different whistles in total, that are used for alerting others about predators or threatening. This gives the Yellow-bellied marmot the nickname "whistle pig". 2004. They measure from 47–68 cm (18 1⁄2–27 in) in length, have a short tail measuring 13–21 cm (5–8 1⁄2 in) with buffy, reddish and black hairs and hindfoot measuring 7–9 cm (3–3 1⁄2 in).[3]. They are capable of rousing enough to eat from their hoard of cached food. They have sturdy bodies with short, wide heads. When above ground, marmots spend much of their time fattening up and resting in the sunshine during the short growing season. Marmots are generally large ground squirrels. Yellow-bellied Marmots (Marmota flaviventris) Hibernate Socially. [1] As there are no major threats to this species and it is protected in several areas throughout its range, there is not much concern for serious conservation efforts to be put in place.[1]. Yellow-bellied marmots eat only plants. Mothers feed their pups milk for about 3 weeks, and then the pups come out of the burrow. The breeding season lasts about two weeks. They sometimes have trouble finding food in the spring, when the ground is still covered in snow. [4] Due to the bright yellow fur on their belly, sides of the neck, and throat, they get their scientific and common names. (Nelson, 1980), Yellow-bellied marmots are hunted for enjoyment, food, or fur in some places where they live. [4] Their feet are yellowish to dark brown to in color. Research by the French ethnologist Michel Peissel claimed the story of the "Gold-digging ant" reported by the Ancient Greek historian Herodotus, who lived in the fifth century BCE, was founded on the golden Himalayan marmot of the Deosai Plateau and the habit of local tribes such as the Brokpa to collect the gold dust excavated from their burrows.[19]. Additionally, four extinct species of marmots are recognized from the fossil record: Marmots have been known since antiquity. [5] Their back is reddish-brown in color with grizzled black and light-grey tan. Marmots are one of the largest members of the squirrel family. Collins, 1984. They hibernate for approximately eight months starting in September and lasting through the winter. Not all of the seeds are eaten immediately though. These herbivores are active during the summer when often found in groups, but are not seen during the winter when they hibernate underground. Other species prefer rough grassland and can be found widely across North America and the Eurasian Steppe. During this time of the year, they often concentrate on the fresh, young, tender leaves that nature provides. However, the young are still bonded to their parents for a long time, especially when they are living in colonies. (Blumstein, et al., 2004; Frase and Hoffmann, 1980; Wey and Blumstein, 2010), Scientists don't know much about parental care in yellow-bellied marmots. The etymology of the term "marmot" is uncertain. The feeding habits of marmots are interesting and worth a bit of observation. For example, in the White Mountains of California they only above 2000 m in elevation. These predators include foxes, dogs, coyotes, wolves, and eagles. Marmots inflate as they cook - "It can get as big as a basketball with these four little legs sticking out," Lerner says, and might even explode right in your lap. (Frase and Hoffmann, 1980), Yellow-bellied marmots have many predators that live on land or fly. "Patterns of morphological evolution in Marmota (Rodentia, Sciuridae): geometric morphometrics of the cranium in the context of marmot phylogeny, ecology, and conservation", "The Endangered Siberian marmot Marmota sibirica as a keystone species? An anatomically accurate image of a marmot was printed and distributed as early as 1605 by Jacopo Ligozzi, who was noted for his images of flora and fauna.
