The secret of their success is that sunflower heart seeds are a convenient size for most birds, birds don't have to use valuable time and energy removing a husk and they have one of the highest calorie to size ratios and are filled with essential oils. Definitely the birds equivalent of fast food!! In addition the ease to eat them makes them a favourite of softbills such as Blackbirds, Robins and Song Thrushes.
Rokers Sunflower Hearts, also known as white sunflower seeds, 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. Our 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.
