      The picture you have for a “squirrel” is not a squirrel, it is a chipmunk.

      By sight the easiest thing to identfy them is their tail. Squirrels have a bushy tail that they curl up behind them, while chipmunks have a thinner, straighter tail. Squirrels are also bigger than chipmunks, and can be either red or gray, chipmunks are usually red.
