The favorite of woodpeckers, nuthatches, and chickadees and our number 1 recommendation for attracting them. Contains peanuts, cashews, almonds, and brazil nuts. We recommend this over straight shelled peanuts because their large size has two advantages. It will take the birds longer to remove and eat them from the mesh peanut feeders, so you get to view the bird longer and don't go through it as quickly. A win-win! Especially useful for slowing down starling, grackle, and blackbird consumption. Try using them in either our Mesh Peanut Feeder or the Squirrel Buster Peanut Feeder.. Or put them in a tray style feeder.
