As yearlings, both males and females leave their birth colony to form a new one and are very susceptible to predation. Also known as rockchucks or whistle pigs, yellow-bellied marmots are social creatures that live in communities of 10 to 20 individuals. Mating occurs in spring when they emerge from hibernation, and litter sizes average three to eight pups per female. Marmots have reddish-brown fur and a yellow belly, from which they get their name. While feeding out in the open, one marmot stands as a sentinel and whistles sharply when danger is near. When they looked at what was resulting in those seasonal trends, they found the environmental drivers differed between pups, yearlings and adults. Trending footage shows the rodents having 'an intense fight' on a highway road They can be two feet in length and weigh up to 11 pounds. Keeping groundhogs away after removal. During the morning and afternoon on summer days they feed and spend time sunbathing on rocks. “The better the condition they are in prior to hibernation, the more likely they are to survive,” she said. During the summer, marmot pups that have soon left their burrows are trapped, weighed and fitted with ear tags that have unique ID numbers. Marmots have reddish-brown fur and a yellow belly, from which they get their name. It is illegal in the State of Virginia to trap and relocate an animal to another area. The Alaska marmot (Marmota broweri), also known as the Brooks Range marmot or the Brower's marmot, is a species of rodent in the family Sciuridae.It is found in the scree slopes of the Brooks Range, Alaska.They eat grass, flowering plants, berries, roots, moss, and lichen. An active heart beat of 180 to 200 beats per minute also decreases to an average of 30 beats per minute. But researchers wondered if yellow-bellied marmots (Marmota flaviventris) survival rates differ based on the season. Each of these physiological traits helps ensure they have the energy to survive and reproduce when they wake each spring. Marmots have important adaptations for personal energy conservation. Olympic marmots are relatively easy to see during the summer months along Hurricane Ridge in the Olympic National Park. Olympic marmots eat herbs, grasses, and flowers. Researchers often use mark-recapture analyses to help them estimate annual survival rates for longer-lived species, like marmots. For montane species like marmots, there’s nowhere for them to go as climates warm, Cordes said. Marmots likely survived better in the summer because it’s an active season where the species has access to plants for food, Cordes said.

Olympic marmots hibernate from September to May. They dig elaborate mazes of burrows underneath high elevation meadows and rocky fields. They each build large fat stores that will get each of them through roughly 200 plus days of hibernating. A marmot's day consists of morning and evening feedings, while they spend the middle of the day and nights hidden in their burrows. They enter their burrows in September to early October and don't emerge again until the following April or May. Marmots likely survived better in the summer because it’s an active season where the species has access to plants for food, Cordes said.
