The added kibbled peanuts and sunflower hearts in this peanut butter blend increase the oil content, thus maximising the calorie content, making it a tasty and nutritious treat for your garden birds. Peanuts are naturally high in calories and when blended into butter, make a tasty high energy treat. We haven\'t added any salt into our recipe, ensuring that this blend is nutritionally balanced and safe* for your garden birds. The glass jar contains 330g of this tasty peanut butter blend. Feed by removing the lid and placing the jar into one of our specialist feeders. Alternatively you can feed by sitting the jar securely on a bird table, or by smearing the peanut butter onto the trunk of a tree for more timid birds to find. *Peanut butter intended for human consumption contains up to 100 times more salt than our specialist blend and should not be fed to garden birds or wildlife.
