The Culprit

My title isn't strictly accurate as it's a gang of three which constantly plunder my bird food, nevertheless I've caught this one red handed.  With all the other available bird food at the moment I'm considering at least removing the Sunflower Hearts, which the squirrels mostly go for and leaving (still available for the birds) the smaller seed which they aren't as interested in.  I never thought that such a lot of energy would be put into outwitting these cheeky little creatures  - I'm not winning either.  However despite what I say I really do enjoy seeing them, even if they are eating me out of house and home.
