Liked by woodpeckers, nuthatches, and chickadees and one of the best ways to attract them. Try using them in either our Mesh Peanut Feeder or the Squirrel Buster Peanut Feeder. Also makes a nice treat for squirrels and other critters. If you find the birds are going through them too fast (especially due to starlings, grackles, and blackbirds), than try using the mixed tree nuts.
