Easy-to-assemble small guardian to fit our small Ultimate easy-clean nut & nibble, seed & nyjer feeders. This feeder guardian is strong, durable, & expertly-constructed from powder-coated steel, with no potential foot traps. The cage makes feeders resistant to larger birds & adult squirrels as well as protecting smaller birds from predators. The space between the cage & the bird feeder is wider than in previous designs, making it harder for larger birds & adult squirrels to reach the feeder. Refilling & cleaning the feeder is a doddle. The guardian slips over the feeder, then screws into place.
