Don't use red dyed hummingbird feeder. Instead, use pure cane sugar.
Red dye #40, named Allura Red AC, is petroleum based. Initially it was made from coal tar, but now made mostly from petroleum. It puts stress on the kidneys as it comes out red in their waste indicating that it never gets metabolized. Opt instead for using pure cane sugar with a ratio of 1 part sugar to 4 parts water.
