Shelled peanuts are used in lots of differing types of feeders. Additionally they are generally diced up and included to normal bird seed mixes or suet. I fill a metal mesh feeder with peanuts that only woodpeckers, titmice, chickadees, as well as other birds that could cling can access. http://petshopdubai78777.blogofoto.com/26328164/about-amazon-pets-uae
