With such a high energy lifestyle, hummingbirds need to eat constantly. Hummingbirds easily digest sucrose, so the energy is delivered faster than artificial nectar mixtures. This concentrate makes feeding hummingbirds simple, just add water to create your desired amount of nectar. There's no need to boil it and our nectar requires no refrigeration, making storage a breeze. In addition, this nectar features a clear, non staining formula so there is no need to worry about drips or spills.
