The Great Gray Owl, the largest owl in North America, normally lives in a wide swath of forests sweeping from Alaska across to northeastern Canada. However, this winter Minnesotans have spotted the giant owls all over the state. The Great Gray Owl is a hunter that mostly eats voles, small rodents similar to mice. Last fall, the vole population in Canada fell to its lowest levels since 1992. (Because cold, wet weather is hard on the voles, the population has headed south.) As a result, the Great Grey Owl has had a hard time finding food up north. It has followed its food source and ended up here in Minnesota, south of its usual range.
