Where do tree squirrels live in North America?

In North America, tree squirrels are found across a wide range of habitats, extending from the boreal forests of Canada and Alaska southward through both coniferous and deciduous woodlands in the United States.1

These rodents are highly adaptable; for example, the North American gray squirrel has successfully established itself in urban and suburban environments. While they are primarily arboreal, their specific movement patterns vary by species: some, such as the Eastern fox squirrel, frequently travel along the ground between trees, whereas others, like the Eastern gray squirrel, prefer to navigate through the treetops.1
