what do reindeer eat in the winter

Reindeer are well-adapted to survive in harsh Arctic conditions, and their diet varies depending on the time of year. In the winter, reindeer subsist on a diet of lichen and moss, which they scrape off the ground with their hooves. They also consume small amounts of tree bark and conifer needles, as well as any grass that may be accessible through the snow. Reindeer are also known to eat some aquatic plants and algae that they can find near bodies of water. In the summer, reindeer can graze on a wider variety of plants, including grass, shrubs, and berries.
