Caught in the act

The rooks have learned to lift feeders then dump them on the ground for easy consumption of the contents, and that's what this one is trying to do.  It didn't succeed because I'd secured the feeder to the hook with a Velcro plant tie.  However, later when I wasn't looking, one of the sunflower feeders had been lifted and dumped on the ground.  More Velcro needed I think.
