| Though the pushing and grappling can be quite vigorous, marmots have only to give a sharp yelp to end the bout. |
| Alpine marmots are large ground-dwelling squirrels living in mountain open meadows. |
| Since hoary marmots reproduce biennially, half the females are fertile and half nonfertile during any given year. |
| Their yaks share these high, sunny pastures with blue sheep and plump marmots. |
| Some of these destructive species include beavers, muskrats, elk, deer, voles, marmots, prairie dogs and geese. |
| Squirrels range in size from the mouse-sized African pygmy squirrel to the robust marmots and woodchucks. |
