Perky-Pet Ready-to-Use Red Hummingbird Nectar nourishes and hydrates hummingbirds with a bird-friendly recipe that’s been reverse engineered to mimic the real flower nectar they feed from in nature. It is made with pure cane sugar to provide hummingbirds with the essential energy they need to thrive. The nectar’s all-natural red color is derived from fruits and vegetables and contains no red dye #40. Hummingbirds won’t be able to resist stopping by for a drink! Our sweet hummingbird nectar comes ready to use in a stay-flower-fresh aluminum can so its convenient for you and just right for the hummingbirds. Plus， the unique can design is lightweight and portable to allow for no-spill filling. There’s no need to mix it with water or boil it – just pop it open， pour the nectar into your favorite hummingbird feeder， recycle the empty can， and enjoy watching your hummingbird visitors. The aluminum can is 100% recyclable to ensure zero waste. Just separate the label from the can before recycling both pieces.
