There is absolutely no reason to add any red dyes to hummingbird sugar water. After all, natural flower nectar is clear, and hummingbird feeders have colorful parts that attract hummingbird regardless of the color of the sugar water.
Sheri Williamson of the Southeastern Arizona Bird Observatory (SABO), and author of A Field Guide to Hummingbirds and Attracting and Feeding Hummingbirds, writes, “The bottom line is that ‘instant nectar’ products containing artificial coloring are at best a waste of your hard-earned money and at worst a source of disease, suffering, and premature death in hummingbirds.”
