Being part of their natural diet, insects are a primary source of protein for your garden birds and this Peanut Butter includes dried insects for extra protein along with essential nutrients from tallow and peanut flour to help your garden birds year-round. 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. Note: 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.
