Birds are high energy creatures that require diverse diets. They like to eat a wide variety of foods including fruits, nuts, insects and flowers. As much as they love supplemental feeding, this forms a small part of their diet so you don’t need to worry that the birds will become dependant on your feeder for their survival. However, if you feed the birds during the summer months don’t suddenly stop in the winter. They will have become used to finding a food supply in your garden and they will appreciate your feeder much more through the cold, fruitless winter months.
