Hummingbirds need both protein (small insects) and energy (nectar, or hummingbird food) in order to survive. According to the U.S. Fish and Wildlife Services, a hummingbird will consume "half its weight in sugar daily." Homemade hummingbird food and a well-placed feeder will go a long way in helping this species survive.
An easy hummingbird food recipe is to first boil four cups of water for more than thirty seconds, then mix water with one cup pure cane sugar. Fill hummingbird feeder and refrigerate remaining food for up to two weeks. Refresh every four to five days.
Do not use honey or artificial sweeteners when making hummingbird food, and avoid food dyes. Do not microwave mixture. Do not allow feeder to become dirty or to form yeast. Soak in vinegar or warm sudsy water to clean, making sure to rinse well before returning it outside.
