The tail-prop design of this feeder is ideal for attracting woodpeckers to your backyard. Skerfs below the suet cage provide better gripping service for birds to cling to feed. Made with naturally insect and squirrel resistant bamboo, this feeder is constructed with rust-free screws and mesh and includes a vinyl-coated steel hanging cable for a durable feeder that will last for years of birding enjoyment. This feeder holds one suet cake.
