Packed with energy and essential oils, sunflower hearts are the ultimate bird food. With the husks removed these seed hearts take away all the effort for garden birds saving them time and energy. Sunflower Hearts are loved by a variety of garden birds. With food resources scarcer now, it is essential to feed garden birds all year round. Once you have started to feed the birds it is important to continue this and develop a routine, as the birds will become reliant upon your help. Put out feed at the beginning of the day to ensure that the birds can replace the energy that they have lost over night. It is best to have multiple feeding sites within the garden to prevent overcrowding. Moving them around regularly will prevent a build-up of droppings, which can spread disease and bacteria.
