This 32 oz. bottle of concentrate makes a gallon of feed! Talk to anyone who’s used First Nature Hummingbird Nectar Concentrate and they’ll tell you they won’t use anything else. Our Hummingbird Nectar Concentrate is a premium concentrated formula which contains sucrose, preferred by hummingbirds over monosaccharide glucose or fructose sugars. There are no messy sugars to boil or mix and no sticky cleanup. In fact, you can easily mix one part nectar to three parts water right in the feeder jar. This nectar is RED DYE FREE, has the highest sucrose content, and is Made in the USA.
