Suet is a high-energy, pure fat substance that is invaluable to birds.  Suet has a texture that the birds enjoy and is preferred by birds, with the main ingredient being rendered beef fat. Our suet cakes are made only of pure rendered beef suet and loaded with lots of yummy ingredients, and birds such as woodpeckers, chickadees and nuthatches love to eat. Offering suet at a backyard feeding station is a great way to attract a wide variety of insect-eating birds.
