A straightforward bird food product whose primary ingredient is shelled, raw peanuts (unsalted, unflavored). The peanuts are sold without shells (or with minimal shell remnants) to make them easier for birds to handle and consume. Many birdwatchers favor this type of feed because peanuts deliver high energy, fats, and protein, nutrients that are especially valuable during breeding season, cold weather, or other times when birds need extra fuel.
