    What is the best ratio of sugar-to-water to use for feeding hummingbirds?

    Four parts water to one part sugar has been shown to be the closest to the sucrose content of natural flower nectar. Concentrations stronger than this are readily consumed by hummers, but there may be the possibility that stronger solutions crystallize on the bill and attract bacteria, leading to a condition called bill rot.
