I have made an upside down suet feeder. It looks like a shallow bird house, the roof opens and I slide in suet cakes. It has a grate in the bottem to hold the suet and the birds hold on and feed upside down. The woodpeckers and an occasional wren use it often. Starlings wipe out my hanging suet but do not feed upside down. Fun to watch.
