The Eastern Grey Squirrel (Sciurus carolinensis) is a tree squirrel (as opposed to ground squirrels such as gophers and woodchucks) native to the eastern and midwestern United States and eastern Canada.  It has also been introduced to areas outside its native range in the western United States, and in Britain, where it has all but displaced that country's native Red Squirrels (Sciurus vulgaris).

Eastern Grey Squirrels are herbivores; their diet is made up of the inner bark of trees and a variety of seeds, nuts and acorns.  They coexist easily with humans, and in residential areas they also eat millet, corn, sunflower seeds and other grains and seeds from garden birdfeeders.  The effort to produce a squirrel-proof birdfeeder has resulted in a vast array of inventions, from the simple to the astonishingly complex.

Adult Eastern Grey Squirrels range in body length from about 10-12 inches (23-30 cm), and usually weigh between 14 oz and 1lb 7 oz (400g and 600g).  Their distinctive, long-furred tail is almost as long as their body length, and is usually 7.5 to 9 inches (19 to 25 cm) long.

Squirrels are foragers who do not hibernate in the winter.  They are known for their food-saving behaviors, which are classified as "scatter-hoarding", meaning they make many small caches of food in different areas.  These can be temporary, for the squirrel to return to within hours or days to collect and re-hide somewhere more secure, or can be much longer term.  Squirrels can bury or hide food stores and still find them months later--they have very highly developed spatial memory, which referrs to near and distant landmarks to relocate their food stores.  Adult squirrels are believed to store food in several thousand different places each over the course of a gathering season.
