18" Onyx Clever Clean Finch Feeder. The world's cleanest feeders just got cleaner! This elegant and innovative feeder comes with a removable base that comes apart and reassembles in seconds for the fastest clean ever. A convenient one-touch opening allows the feeder to be filled with one hand even when hanging. The newly added seed tray attracts a greater variety of birds. The black powder-coated 18 in. metal tube is rust-resistant and provides a high contrasting background for feeding bright yellow finches. The small diamond-shaped openings mimic nature and allow for the birds to pull seed out just as they would from a flower in the garden. Backed by the Droll Yankees Lifetime Warranty against squirrel damage.
