Extra Select Sunflower Hearts, also called white sunflower seeds, these are bakery grade kernels produced from black oil sunflower seeds. This means they are from the sunflower which contains the highest levels of oil and therefore energy rather than the confectionery grade hearts which are mainly taken from medium and large striped sunflower seeds. Extra Select sunflower hearts are also put through a sortex machine which uses lasers to colour detect any black husk still remaining, producing a uniform and totally husk free sample. We use these same excellent sunflower hearts in our blends, we dont substitute lower grades in any way. Best fed from feeder or wild bird table Complementary food for wild birds may contain nuts. Not intended for human consumption. Store in a cool. dry place below 14%.
