It is hard to guess what a Yellow-bellied marmot weights. But we have the answer:
An adult Yellow-bellied marmot (Marmota flaviventris) on average weights 3.71 kg (8.18 lbs).
The Yellow-bellied marmot is from the family Sciuridae (genus: Marmota). It is usually born with about 33 grams (0.07 lbs). They can live for up to 8 years. When reaching adult age, they grow up to 41.2 cm (1′ 5″). On average, Yellow-bellied marmots can have babies 1 times per year with a litter size of 4.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
The yellow-bellied marmot (Marmota flaviventris), also known as the rock chuck, is a large, stout-bodied ground squirrel in the marmot genus. It is one of fourteen species of marmots, and is native to mountainous regions of southwestern Canada and western United States, including the Rocky Mountains, Sierra Nevada, and Mount Rainier in the state of Washington, typically living above 6,500 feet (2,000 m). The fur is mainly brown, with a dark bushy tail, yellow chest and white patch between the eyes, and they weigh up to approximately 5 kg (11 lb). They live in burrows in colonies of up to twenty individuals with a single dominant male. They are diurnal and feed on plant material, insects, and bird eggs. They hibernate for approximately eight months starting in September and lasting through the winter.
