The woodpeckers, titmice and other nut and fruit loving birds in your backyard will love it. Standard sized suet cake will fit in most standard sized suet holders. If you have problems with grackle, blackbirds and starling getting to your suet, try using an upside down suet feeder, available at Barn in the Sticks.
