Suet is a high energy food made from animal fat and is usually sold with seeds embeeded. Suet feeders are mesh containers which hold suet blocks and allows "clinging" birds to feed through holes. They will attract woodpeckers, chickadees, nuthatches, kinglets, cardinals, and creepers.
Suggestion: Cut the hardware cloth 8" wide (instead of 10"), allowing 1" over hang on each side (still lots of room for those 5 1/2" suet squares) and ables you to cut 3 strips from a standard 24" wide hard cloth roll (less waste, lower cost). Note that the dowel (old broom handles work well) should therefore be only 7 1/4" in length.
Hummingbird feeders are a real favorite for attracting the color, speed, and aerial acrobatics of this small but fascinating bird. They are inverted containers filled with nectar, or sugar water, that is dispensed through tiny holes. Keep it clean, as mold and fermentation can occur within a couple of days.
