Hang suet (beef fat) from tree branches by packing it into a wire suet basket or a mesh onion bag.
This high-energy food attracts woodpeckers, nuthatches, thrushes, titmice, and other birds.
Make seedy suet cakes easily and economically. Just combine one part peanut butter, two parts birdseed, and five parts cornmeal to each part melted beef suet (available in the meat section of your grocery store). Press the mixture into muffin tins. Let harden. Drop a suet cake into a net bag and hang from a tree branch.
