The grey squirrel is a common species found in North America and parts of Europe. It has a bushy tail and soft, grey fur, which helps it blend into its surroundings. These squirrels are known for their agility and can often be seen climbing trees or foraging for food on the ground. They primarily eat nuts, seeds, and fruits, and are particularly fond of acorns. Grey squirrels are social animals and often live in groups. They build nests, called dreys, in tree branches using leaves and twigs. While they are a familiar sight in parks and gardens, they can sometimes compete with native species, such as the red squirrel, for food and habitat.
