A variety of insect, berry, and seed eating birds are drawn to Blue Seal® Suet. The high fat content in suet provides the energy wild birds need, especially during the cold winter months. Woodpeckers, Nuthatches, Chickadees, Titmice, and the Northern Flicker are common visitors at the suet feeder. Suet may also be used to attract the less common and more elusive Yellow-rumped Warbler, Brown Creeper, Carolina Wren, Summer Tanager, Eastern Bluebird, and Gray Catbird. Blue Seal offers suet cakes in a variety of flavors.
