Our Sunflower Hearts Wild Bird hearts are superb for little garden birds that need to eat without the risk of predators. Loads of protein and energy are stored directly within the hearts, so birds can refuel quickly and fly away at the first sign of trouble. Finches love them and sparrows, tits and blackbirds, too! Size: 4kg. Feeding Guidelines: Feed them in a feeder, on a table or directly on the ground. For wild birds to thrive in your garden, they need your help all year round so please keep feeding them in the spring and summer and top up their fresh water supplies - especially during freezing winter weather. Once you have established a feeding pattern please try to keep to it so that you don't disappoint your garden visitors. Composition: 100% Sunflower hearts. Storage: Store in cool, dry conditions.
