Also known as golden safflower, birds prefer this seed over normal safflower and you will attract more songbirds. This birdseed is higher in oils, fats, and proteins compared to normal safflower. This means more flavor for the birds and a thinner shell for easier digestion. Nutra-safflower is higher quality than normal safflower and will still drive away any of the blackbird family. Including Grackles, Starling, and Cowbirds.
