Help your backyard birds stay cozy this winter by serving up high-energy treats like suet and peanuts. Since these power foods offer twice the calories of regular seeds, they are a true lifeline for woodpeckers and chickadees in the biting cold. A simple mix of nuts, mealworms, and black-oil sunflower seeds is all it takes to keep a vibrant, happy variety of species visiting your home throughout the harshest months.
