Marmots eat herbs, grasses, young shoots of plants and roots.
Due to the rather high nutritional value, marmots quickly accumulate a lot of fat during the short growing season of the alpine summer. This is essential for the next winter, because then they need good reserves to survive hibernation.
In addition to plants as the main food source, insects, larvae and earthworms are also on the menu, depending on availability.
These alpine inhabitants do not cover their liquid requirements at the clear mountain streams, but exclusively by solid food.
