About 20 ft outside our kitchen window we have an old rotten stump that we have built a small platform sunflower feeder on.  Several times a year the very large Pileated woodpecker will vist this stump to peck grubs and worms out of the rotten wood.  It seldom eats the seeds but will peck away at the stump.  It stopped by the other day to have a snack and gave us an great show.
