How to Make Hummingbird Nectar?

It's easy to make hummingbird food with just table sugar and water.
Use table sugar rather than honey to make hummingbird food—when honey is
diluted with water, bacteria and fungus thrive in it. The normal mixture, especially ideal during hot or dry weather, is ¼ cup of sugar per cup of water. During cold, rainy, or foggy conditions when fresh water is plentiful but birds need more energy, it's fine to make the mixture ⅓ cup of sugar per cup of water.
Concentrations of sugars in natural nectar vary within about that range.
If you mix up small quantities of sugar water every day or two, there's no need to boil the water. But if you mix up larger batches and refrigerate part for later use, then it's wise to make the mixture with boiling water.
