Eastern Gray Squirrel (Sciurus carolinensis)

The Eastern Gray Squirrels live in woodlands and urban areas throughout the eastern and midwestern US and eastern provinces of Canada2. 

These agile creatures are most active during sunrise and sunset. Eastern Gray Squirrels also store food in secret stashes, which benefits them and the environment by spreading seeds far and wide.

One of their most impressive tricks is their unique agility. For instance, their ankles can rotate 180 degrees, allowing them to make a death-defying head-first descent down trees.
