It's well known that if you're going to feed one kind of seed to garden birds, it should be Sunflower Seeds as they are readily accepted by more birds than any other kind of seed. They will provide garden birds with the high fat and high energy that they'll need, especially in the winter months.
Sunflower Hearts are simply the hulled, shell-less inside of a Sunflower Seed. Wild birds will want to reserve as much energy as possible and will readily take Sunflower Hearts over Sunflower Seeds as the latter require the bird to crack them open. This will especially be true in Winter when their energy levels are even more important. This also makes it easier on us humans as we have no clearing up of the shells once the birds have fed off the Sunflower Heart inside. 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.
