Hand-crafted mix is designed to attract more cardinals to your feeder. This beautiful blend features a variety of sunflower seeds that attract wild birds with prominent seed-cracking bills, like cardinals, jays, and grosbeaks. This mix also includes golden safflower, an organic, chemical-free hybrid safflower. Golden safflower has higher nutrition content than white safflower, with 15% more oil, 25% higher protein and 30% higher fat. Golden safflower has an extremely thin hull, making it easier for birds to eat and digest.
