The red squirrel is a small tree-dwelling rodent native to Europe and North America. It has a bushy tail, reddish-brown fur, and is known for its agility in climbing trees. Red squirrels primarily feed on seeds, nuts, and fruits, often storing food for winter months. These squirrels are typically found in coniferous and mixed forests, where they build nests in tree branches. Unlike the larger gray squirrel, red squirrels are more solitary and territorial. Their populations are affected by habitat loss and competition with gray squirrels, which have become more common in many areas.
