When creating a burrow, they use both their forepaws and hind feet to assist in the work—the forepaws scrape away the soil, which is then pushed out of the way by the hind feet. If there are any stones in the way, the alpine marmot will remove them with its teeth provided that the stones aren't too large. Living areas are created at the end of a burrow, and are often lined with dried hay, grass and plant stems. Any other burrow tunnels that go nowhere are used as toilet areas. Once burrows have been completed, they only host one family, but are often enlarged by the next generation, sometimes creating very complex burrows over time. Each alpine marmot will live in a group that consists of several burrows, and which has a dominant breeding pair. Alpine marmots are very defensive against intruders, and will warn them off using intimidating behavior, such as beating of the tail and chattering of the teeth, and by marking their territory with their scent. One can often see an alpine marmot standing while they keep a look-out for potential predators or other dangers. Warnings are given, by emitting a series of loud whistles, after which members of the colony may be seen running for cover.
