Eastern Gray Squirrel
One of the most common squirrels seen in this area is the Eastern gray squirrel. This rodent species is found throughout the United States, primarily in the East and Midwest, and in southern Canada. In Europe, they are considered an invasive species. In North America, they can be found in urban areas, suburban places, and rural regions. This common squirrel gets its name from its predominantly gray color. Their undersides are mostly white and sometimes this squirrel may also appear brown. Eastern gray squirrels spend their time gathering food and storing it in their dens. They have up to two litters per year. They are attracted to backyards with birdseed and other food sources. They may make a nest in the eaves of a roof, thinking it is a tree cavity. If this happens, they can get inside the home’s walls and ceilings and cause significant damage.
American Red Squirrel
Another squirrel seen in Milwaukee neighborhoods is the American red squirrel. This species of squirrel is smaller than the gray squirrel and more territorial. It also has a characteristic reddish appearance. They live throughout North America. American red squirrels are found all over Canada and in the northeast and Rocky Mountain regions of the United States. American red squirrels mostly nest in hidden crevices of trees and occasionally below ground. They eat a variety of foods, such as nuts, seeds, mushrooms, berries, and bird eggs. They typically breed once per year and usually produce a litter of three to six young. Sometimes, they find their way into a shed, attic, or basement and store nuts or seeds inside. They may also nest in a home and leave behind damage such as chewed wires and droppings.
Fox Squirrel
The third squirrel frequently seen in the area is the fox squirrel. This squirrel is the largest of the three species of Milwaukee squirrels, with an adult weighing up to two pounds. Their coloring is similar to the Eastern gray squirrel, with a mostly gray body, a white underside, a bushy tail, and some brown shading in their fur. Fox squirrels live in most parts of the eastern and Midwest United States and some places in Canada. Certain populations of fox squirrels may have a different coloring, such as brown and gold or black. In the wild, they have similar behaviors to the other common squirrels. Fox squirrels are also able to make nests out of leaves. They also have adapted their diet to their geographic region and habitat.
