Wikipedia Abstract

The yellow-bellied marmot (Marmota flaviventris), also known as the rock chuck, is a ground squirrel in the marmot genus. It is native to mountainous regions of the western United States and southwestern Canada, including the Rocky Mountains, Sierra Nevada and Mount Rainier in Washington State, 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 about 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 about eight months from September till the weather warms up.
