Unlike animals with binocular vision, they can see who's approaching them from behind, to some extent. Then again, without depth perception, how could squirrels leap from branch to branch and tree to tree seemingly without ever missing? Are they just <em>really</em> lucky? Someone ought to dredge up a biologist who specializes in squirrels to get these questions answered. And by "someone," I mean "not me, perhaps Colter."
