When people are trying to learn about squirrels they often get confused by all of the different names. A squirrel will often have multiple common names and those names will often overlap with the common names of other species of squirrels. For example, in the US there are three distinct species of tree squirrels that are called “Gray Squirrels” (Eastern, Western and Arizona).
Another point of confusion is that the squirrel family encompasses many more creatures than just the common tree squirrels that we see in our backyards. It turns out that creatures as diverse as chipmunks and groundhogs are also technically considered to be squirrels!
After you sort through all of the confusion and add up all of the different types of squirrels in the world you will find that there are 289 different species!
