To make homemade treats for wild birds, combine seeds and grains with peanut butter or lard. For instance, to make birdseed balls, tie a length of string onto a button, and heat 1/2 cup lard and 1/4 cup peanut butter until the mixture is softened and well-incorporated. Add 2 cups of assorted birdseed to the mixture, allow the mixture to cool slightly, and form the birdseed balls around the button. Use the string to hang the birdseed outdoors.
Another option is to make a pine cone bird feeder. To make the feeder, tie a string to one end of the pine cone to hang it, and spread an even layer of peanut butter over the cone. Roll the pine cone in bird seed, and hang the feeder outdoors.
Suet is also a nutrient-dense treat for wild birds. To make suet, combine 2 cups cornmeal, 2 cups quick-cooking oats, 1/3 cup sugar and 1 cup flour, and set the mixture aside. Melt 1 cup vegetable shortening and 1 cup chunky peanut butter together, and add the mixture to the dry ingredients.
Spread the warm mixture in a baking dish that is approximately 1 1/2 inches in height to cool. Cut the suet into squares, and hang the suet outdoors in mesh bags.
