In-shell peanuts are as much fun for the birders as they are for the birds. Popular with jays, they are a great source of energy for birds. When jays are preparing for winter, they like to store the in-shell peanuts under leaf cover. So, setting out in-shell peanuts for your neighborhood bird population helps the birds prepare for the long winter months ahead. | Nature's Own In-Shell Peanuts Wild Bird Seed | Size 4 lbs
