Woodpeckers will love the unique blend of ingredients that make up each Kaytee Woodpecker Cake. These seed cakes feature Sunflowers, Peanuts, Safflower, Pecans and Pine Nuts. Lasts longer than messy loose seed. There’s no feeder cleanup or removal of old seed to worry about. For best results, place cake in a Kaytee Feeder Station. They are also popular with Chickadees and Nuthatches too.
