The red squirrel closed its eyes for just a moment, paws together, fur fluffed, then resumed its search for food. Winter is a tough time for northern animals. Some hibernate to escape its rigors, but not red squirrels. Mats walks every day in the forest near his home in southern Sweden, often stopping to watch the squirrels foraging in the spruce trees. Though their mainly vegetarian diet is varied, their winter survival is linked to a good crop of spruce cones, and they favor woodland with conifers. They also store food to help see them through lean times. On this cold, February morning, the squirrel’s demeanor encapsulated the spirit of winter, captured by Mats using the soft-light grain of black and white.
