Now you can offer nectar to birds without the fear of artificial dyes with More Birds® Bird Health+™ 32 oz natural grape liquid hummingbird and oriole nectar concentrate. Our nectar has no artificial dyes or flavors. Simply mix one part liquid concentrate with three parts warm water, then stir until completely mixed-no boiling required. One 32 oz bottle of concentrate makes 128 oz of nectar. The resealable container allows you to only use what you need, while the leftover nectar in the bottle always stays fresh. Vitamins and calcium are added to promote successful egg hatching. More Bird®'s nectars are made from a blend of natural sugars found in flowers that birds feed from.
