Hang up the Royal Wing Hi-Energy Suet Cakes and watch as birds come by for a bite to eat. Many species of wild birds, including chickadees and woodpeckers, love the ingredients used in these suet cakes. The rendered beef suet, black oil sunflower seeds and whole grains combine to provide high-quality nutrition and energy for birds. Plus, they can be enjoyed all year round. Place the suet cakes in any standard suet basket (sold separately) and hang where desired. Each hi-energy suet cake weighs 11 oz., providing plenty of food to go around.
