Four Seasons gets its name because it is a perfect everyday choice and is great for feeding birds all year round or seasonal bird feeding. This popular blend is a favorite of many wild birds, including cardinals, chickadees, doves, finches, jays, juncos, nuthatches, sparrows and titmice. This wild bird food blend contains only nutritious ingredients. Therefore, like all Nature’s Window wild bird food blends, Four Seasons is free of wheat and fillers.
