Vibrant Life Economy Blend wild bird food is a simple, everyday seed mix for many types of wild birds. It is made with grains, millet, and black oil sunflower seeds that birds love. This blend provides good energy and is great for feeding birds all year long. It attracts popular feeder birds like cardinals, finches, jays, and flickers, as well as ground feeders such as sparrows, doves, juncos, and towhees. Use this seed in tube, hopper, or platform feeders.
