"There for a reason, birds come for the apples left on the tree as a source of food. I alway leave a quite a few. The little that is left, means little to me, but makes one big difference for them. I try to keep my feeders full also. One in each in the front and one in the back. We I am feeling down and see them feeding, it brightens my day. Fat that surrounds the beef kidney is one of the best to use also. Can be bought cheap at the meat packing house. Long story for apples."
