How Many Squirrel Species Are There Worldwide?

Squirrels belong to the family Sciuridae, which includes tree squirrels, ground squirrels, flying squirrels, marmots, and prairie dogs. These animals are found on nearly every continent and adapt to a wide range of habitats, from dense forests to urban neighborhoods. Knowing how many species exist worldwide provides perspective on their diversity and helps explain why they are such successful survivors.

Number of Species

Scientists recognize more than 270 species of squirrels worldwide. These species are divided into three main groups: tree squirrels, ground squirrels, and flying squirrels. Each group has adapted unique behaviors and survival strategies, making squirrels one of the most widespread mammal families on Earth. In North America alone, there are dozens of species, ranging from the common gray squirrel to specialized flying squirrels found in dense forests.

Habitats and Adaptability

Squirrels thrive in forests, grasslands, deserts, and cities. Their ability to adapt to human environments is part of why they are so common in neighborhoods and backyards. Tree squirrels build nests high in trees, while ground squirrels dig burrows for shelter. Flying squirrels glide from tree to tree at night, using skin flaps to move between branches. Their adaptability ensures survival across continents. This remarkable versatility explains why squirrels have successfully spread to diverse climates worldwide, from the cold boreal forests of Canada to the arid landscapes of Africa and Asia.

Why This Matters for Homeowners

Understanding the number and variety of squirrel species highlights why they are such common household pests. Whether tree squirrels nesting in attics, ground squirrels undermining lawns, or flying squirrels chewing wires in crawlspaces, different species present different challenges. Knowing which species you are dealing with helps determine the most effective removal strategy.
