With a 1.25 quart capacity, the Aspects Medium Spruce Peanut Silo is constructed of stainless steel wire mesh with a die-cast top and bottom with a durable, spruce-colored finish. A triangular diverter at the base of the tube ensures that all seed is accessible to the birds. This feeder is perfect for acrobatic birds such as woodpeckers, chickadees, titmice, nuthatches and finches that can cling to the stainless steel wire mesh tube. Can be filled with shelled peanuts, mixed nuts or sunflower kernels.
