Clever rook

It couldn't reach the fat balls from the ring it was perched on, so it lifted the feeder with its beak until it could grab it and hold it with one of its feet. You can just about see in the photo that there is a claw round one of the wires of the feeder.  The feeder is tied to the support because on Friday I found it on the ground - a rook must have been trying the same trick, I reckon.
