The Gardman Suet Block is made with premium quality suet which provides birds with a complementary source of food when natural resources are depleted. Mealworm is a proven favourite with wild birds, and is a proven hit when teamed with the berry flavour of this block. This brightly coloured block is sure to attract a wide range of wild birds to your garden including robins, finches, blue tits, great tits and long tailed tits. These blocks are the perfect refill for the pre-filled Block Feeder!
