Hoary Marmot

Open encyclopedia reference

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.

It is the largest North American ground squirrel and is often nicknamed "the whistler" for its high-pitched warning issued to alert other members of the colony to possible danger. The animals are sometimes called "whistle pigs". Whistler, British Columbia, originally London Mountain because of its heavy fogs and rain, was renamed after these animals to help make it more marketable as a resort. The closest relatives of the species are the yellow-bellied, Olympic, and Vancouver Island marmots, although the exact relationships are unclear.
