Is the red dye that is found in premixed hummer solution bad for hummingbirds?

[Andrew]

Though no conclusive scientific evidence exists showing harmful effects of red food dye on hummingbirds, this additive is certainly not necessary. Brightly colored flowers are nature’s way of attracting a foraging hummingbird. When they feed at a series of flowers, hummers are acting as pollinators. So the red solution in feeders is aimed at attracting hummingbirds as red flowers are. Bright red feeder parts or a bright red ribbon hung near the feeder can be just as attractive as red-dyed solution. In fact, even with no color at all, hummers will find the feeder.
