Pumpkin Bird Feeder
For a seasonal supplement to your regular bird feeder, cut a 3- to 5-pound pumpkin in half; scoop out, leaving a 1/2-inch thick wall. Cut a 1/2-inch-deep groove in the rim for pumpkin seeds. For perches, poke holes and insert twigs. To hang, knot two lengths of twine together in center; tack knot to feeder bottom. Fill with birdseed.
