Why is the one you want always at the Bottom?

We haven't seen many squirrels in the garden this year, just the odd one visiting occasionally but over the last week they seem to have rediscovered us and I now see at least three frolicking on the lawn and using the squirrel box every day. As you can see they have managed to break the front of it but the blue tits love it because they can hop in front of the hole and score themselves a whole peanut :-)) They thought Christmas had come early last week because Tufty had pulled the front right off exposing all the peanuts, I watched a few of them land, stare at the bounty in disbelief, look around for a trap, then dive forward to grab a nut and make a quick exit....try as I might I couldn't snap them in action, they were just too quick for me but I'll keep trying :-)))
