With such a high-energy lifestyle, hummingbirds need to eat constantly. Perky-Pet red liquid hummingbird nectar concentrate is made of 100% sucrose so your hummingbirds get just the essential energy they need to thrive. Hummingbirds easily digest sucrose, so the energy is delivered faster than artificial nectar mixtures. This concentrate bottle makes feeding hummingbirds simple, just add water to the concentrate 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 bold red color that mimics the vibrantly colored flowers that hummingbirds imbibe from in nature. They won't be able to resist stopping for a drink.
