Black Squirrels

I put up this squirrel feeder outside my kitchen window ... when it gets damp, the wood swells and the lid wont close, but it still keeps the food dry.
We have a lot of grey squirrels around here and two black ones ... they're so entertaining.
This is one of the blacks who's getting food the correct way .. lift the lid and help yourself! We have one grey squirrel ("Stupid") who doesn't quite get it .. "here's your sign" ... he couldn't figure out how to get to the food so he started chewing the wood .. up and down both sides and across the lid ... then he started on the platform ... it's down to a small square now about 2" x 2" .... and even when the lid was sticking up, he couldn't see how to get to the food! His solution: he sits ON the lid, bends over and picks up food from the platform in front.
I hope he doesn't procreate!
