The squirrel-resistant peanut feeder that really worksThis chew-proof feeder drives squirrels nuts. The weight of climbing squirrels automatically forces the shroud down, shutting off the feeder ports. The patented spring tensioner can be adjusted to exclude just squirrels, or larger birds like pigeons too. The feeder’s unique base design offers plenty of perching space for nut-loving species like woodpeckers.
