Royal Jubilee Granola Stacks Sweet Songs are formulated to attract gold finches, juncos and chickadees. Use as a secondary feeding opportunity to compliment their base seed blend diet. The Granola Stacks are blended with sunflower, millets, safflower, nyjer and peanuts. Stacks are hard pressed to mimic natural feeding and must be fed on the Royal Jubilee Granola Stack Feeder purchased separately. Simple and easy to feed. Try an assortment of Granola Stacks on your feeder for a wider variety of birds or put 4 Sweets Songs on the feeder for maximum visits of all colourful and friendly birds.
