Recently, a suet feeder--and the suet cake, of course--disappeared from our bird feeding station. I bought another one, and it too disappeared. Also, I began noticing that our bird feeder is completely empty every morning, no matter how much seed was left in it at sundown.
I set up a camera with a wireless controller and kept a watch out the window. Sure enough, at about 8:30 p.m. I caught this bandit in the act. Repeated flashes didn't seem to bother him. He remained on station, eating until the feeder was empty.
I couldn't get him to return our suet holders. --EFP
