Do you mean the black sunflower seeds?
No, its Safflower birdseed. I get it at www.prdseed.com but I have also purchased it at Home Depot, Lowe’s and the squirrels leave it alone. The Cardinals, Doves, Chickadees and others love it. You can also google it and it will tell you more about it. I’m so glad I found it because even though I like the squirrels, they would eat all the birdseed until it was gone. Safflower birdseed, they leave alone.
