What is hummingbird “nectar”?
Hummingbird nectar is nothing more than table sugar and water. You can make your own by adding 1/4 cup of sugar to a cup of boiling water. Hummers eat insects for their protein. There is no evidence that these tiny birds need vitamin and mineral supplements. There is also no evidence that adding red food coloring to nectar will harm the birds, but it probably is not necessary to attract them. Just put your feeder near red flowers. Please remember, sugar water will ferment when left in the hot sun. Fermented nectar is deadly. Do not put out a feeder if you are not willing to clean it at least weekly, preferably twice a week.
