In winter, woodpeckers eat a greater variety of nuts, including acorns, beechnuts, and pine nuts. Any yard with nut-bearing trees is likely to be a favorite feeding area for hungry woodpeckers. Offering supplemental feeders in all seasons is a great way to offer more food to attract more woodpeckers. Woodpeckers have a varied diet and will eat insects, nuts, berries, sap, and other natural foods. They will also enjoy suet, peanuts, black oil sunflower seeds, peanut butter, and mealworms offered in supplemental feeders.
