Squirrel Proof Feeder is a classy clear bird feeder baffle with peanut spiral bird feeder below. The Squirrel Proof Feeder baffle has an 20" diameter. The Spiral Feeder is 17.5 inch tall with a spiral arm wrap. Birds love to Run the Spiral instead of flying to another perch. The spiral allows cardinals, grosbeaks and other desirable large songbirds to feed. With normal perch tube feeders, these birds have difficulty feeding without a seed tray. Use with sunflower seeds or peanuts to attract all of these birds. The feeder has aluminum and stainless steel parts. Squirrel proof easy twist and lock lids come completely off for easy cleaning, so no screws to mess with. Looped wire hanging cable included (150 lb test) and is attached to cap so you don't have to wonder where you put it. Feeders come completely assembled and ready to hang in your yard. Fill with peanuts, sunflower seeds or mixed nuts and watch how fast the birds are attracted to this Spiral Perch feeder.
