Aspects' Peanut Silo is a selective feeder-only acrobatic birds such as woodpeckers, chickadees, titmice, nuthatches, and finches can cling to the perchless stainless steel wire mesh tube. When filled with shelled peanuts, mixed nuts, or sunflowerkernels, the Aspects Peanut Silo is irresistible to the most entertaining group of birds.
