For many years this variety of sunflower seed was the favorite for most of our backyard friends. Originally grown for human consumption, the surplus stock went to our feathered friends. Most birds will eat any type of sunflower but if given a choice, Blue Jays and cardinals will eat the Striped Sunflower first. Many people have great success by offering this seed in a separate feeder. Cardinals and Blue Jays prefer post mounted feeders but can be attracted to the hanging tubular variety if they have a larger seed catcher tray and substantial perches.
