I grew up in Wisconsin.
I hunted, harvested, and ate quite a few fox squirrels while growing up.
They are found mostly in oak woodlots and mixed oak and white pine forests in Wisconsin.
In Florida they are just about exclusively found in pine forests.
You’re one up on me then. I’ve never even seen a fox squirrel. We’re ate up with the little gray buggers, though.
Of course, we’re ate up with moccasins too, so I guess squirrels that don’t spend most of their time in the trees don’t last long ;-)
