Reindeer are ruminants, having a four-chambered stomach. They mainly eat lichens in winter, especially reindeer moss. However, they also eat the leaves of willows and birches, as well as sedges and grasses. There is some evidence to suggest that on occasion, they will also feed on lemmings,arctic char, and bird eggs. (this info is directly from wikipedia) Thinkin' about painting it...thinkin'
