Starlings are hammering my suet cakes...
We borrowed the simple design depicted
near the bottom of this page; the Starling Stumper . A regular old suet cage with a couple of feet of cheap, lightweight chain (open/close the chain links with pliers). When you put in the suet cake, leave the plastic tray on it like a hat. It won't stop the all of them, but deters most. The remaining peckers, tit mice, nuthatches, etc are very comfortable inverted.
