Feeding with suet cakes and seed cakes is quick and easy. Suet feeders and seed cake feeders are most often cages designed to offer a full surface area for birds. These simple feeders are great year-round, but especially convenient and effective in snowy weather. During the winter, natural food sources are scarce and it can become difficult to feed with mixed seed. Since this style typically lacks ample perching space, it is ideal for excluding larger birds. Suet feeders are highly attractive to woodpeckers, which often cling and use their tail for stability when they feed.
