Extra Select Black Sunflower Seed - a high oil, black sunflower which has also been selected and correctly harvested to produce the maximum oil content. Black oil sunflower must not be harvested late as this produces a high acid content and must be fully matured or you just get empty husks. The black oil sunflower seeds are screened, graded and then a little vegetable oil is added to give them extra shine so the birds can spot them more easily! (It’s true!) plus they are absorbing nutrients even as they remove the husks to get at the seeds themselves. All critical for the long term health of our birds.
