Mix your hummingbird feeder nectar.
Dissolve one part white sugar in four parts hot water. Boil the water if you plan to store the nectar in the refrigerator. Never use honey, which ferments easily, or artificial sweeteners, which have no food value for birds. Red food coloring is not recommended as it may be harmful to birds. Many hummingbird feeders are already red, the hummingbird’s favorite color.
