This wild bird peanut feeder will attract Wild Birds to your Garden. Peanut feeders are made of steel mesh, and are the only safe method of offering nuts to wild birds. The mesh size needs to be large enough to prevent beak damage and small enough to prevent large pieces of nut from being removed – about 6 mm is a good compromise. These are designed for sunflower seeds and seed mixes labelled feeder seed. They will attract tits, siskins and greenfinches.
