Black Oil Sunflower seeds have 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.
They are also triple screened and graded and then vegetable oil is added to give them extra shine so the birds can spot them more easily. 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.
Suitable for Blue Tits, Coal Titis, Dunnocks, Bramblings, Chaffinches, Gold Finches, Great Tits, Sparrows, Nuthatches, Siskins, Yellow Hammers
