3 cups boiling water added to 1 cup sugar, stir , let cool to ensure sugar and water are mixed. ad one or 2 drops of red food coloring to enable you to see the level. they will come without the food coloring.

You need to keep the feeders cleaned, or molds will grow because of the sugar and the birds will get sick if you dont. You can also add honey in place of sugar.
