I saw one with a bright white tail tip once, but never all white. I did have a squirrel around the house here a few years back that had a strawberry blond tail. I'd talked to some others who had seen squirrels like that before

 

Hanging out by my tree stand last year

 

yes

 

also seen a black squirrel with a gray tail near my camp

 

I’ve seen a black with a gray tail too

 

I've been seeing what I call piebald squirrels around here for the last 3 years...never saw them before that.

 

All we have around Enola is greys and these.
