With Perky-Pet Pure Ready-to-Use Clear Hummingbird Nectar, it's love at first taste! This bird-friendly formula is made with pure cane sugar and contains no red dyes. Hummingbirds won't be able to resist stopping by for a drink! Because of their high-energy lifestyle, hummingbirds need to eat constantly. Perky-Pet Pure Hummingbird Nectar boasts 100% more sugar than standard Perky-Pet liquid RTU nectars to provide hummingbirds with the essential energy they need to thrive. Hummingbird nectars mixed with sucrose more closely mimic natural flower nectar than artificial fructose and dextrose mixtures. Hummingbirds more easily digest sucrose, so the energy is delivered faster! Our sweet hummingbird nectar comes ready to use so it's convenient for you and just right for the hummingbirds. There's no need to mix it with water or boil it – just pour into your favorite hummingbird feeder and go! Plus, the unique bottle design allows for no-spill filling. Be sure to clean and refill your hummingbird feeder on a regular basis to ensure healthy, happy hummingbirds.
