Safflower seeds

If you use only Safflower seeds, you will feed the “Goldfinches” and other birds with out feeding squirrels.  Sunflower hulls have an effect on seeds so that nothing can grow where the hulls pile up under the feeders but the safflower seeds do not.  The four footed critters are not even interested in the food in my feeders.
