Red-shafted Flickers are common here, and I ordered two "special" suet feeders which have extensions for the big bird's tail. This winter, three Flickers have been regular visitors; they are often accompanied by a Downy Woodpecker. The problem with any winter bird-feeding are the "undesirables" such as starlings. They prefer suet and can devour a suet block fairly quickly. The little birds such as black-eyed Juncoes, chickadees, house finches and pine siskins have two seed feeders close to the suet.
