Sunflower Hearts are well known in the bird feeding community to be one of the best bird seeds to feed your garden birds over any others. They are accepted by more birds than any other kind of seed such as Tits, Finches, Dunnock, Sparrows, Pigeons, Doves and Thrushes.
Sunflower Hearts are the inside nutmeat of a Sunflower Seed, they've just had their shells removed. Wild birds will always examine a seed and decide whether the effort it takes to open the seed is worth it for the amount of energy they'll receive off the nutmeat inside. Sunflower Hearts make this decision even easier for them as the job is already done! The huskless seeds also make it easier for us humans, as their is no need to clean up the leftover shells. Since the shells of Sunflower Seeds contain a component that is toxic to grass, this is an important factor for many people in choosing whether to offer Sunflower Seeds in or out of the shell, in case any drop to the garden grass.
They are suitable for all kinds of standard seed feeders as well as sprinkled onto the floor or a bird table.
