Eastern Gray Squirrel

When a squirrel is alarmed, it flicks its tail; when it's feeling aggressive, it fluffs it up. During its breeding season, a squirrel will wave and shiver its tail while approaching the opposite sex. 

 And yes, as you might imagine, a squirrel will also use its big, fuzzy tail to keep itself warm and toasty--it'll wrap its tail around itself like a built-in security blanket during wintertime. A squirrel will also use it to cool off during the summer. In hot weather, the tail becomes a sunshade for the squirrel and helps protects it from the sun's burning rays. Now that's one cool customer! 


Cute squirrel.

I would say he is trying to camaflouge himself with his tail, he is a bit jittery with all the attention.
