Please, do not put honey, Jell-O, brown sugar, fruit, or red food coloring in your feeder!Honey ferments rapidly when diluted with water and can kill hummingbirds. The effects of red dye have not been not scientifically tested, and it is not necessary to color the water to attract birds to your feeder. Further, there are unverified reports that red dye can cause tumors in hummingbirds; this may or may not be true, but why take the chance?
Here's a recipe for artificial nectar (syrup):
Use one part ordinary white cane sugar to four parts water.
It's not necessary to boil the water. The microorganisms that cause fermentation don't come from the water; they are transported to the feeder on hummingbird bills.
Store unused syrup in the refrigerator for up to two weeks.
This mixture approximates the average sucrose content (about 21%) of the flowers favored by North American hummingbirds, without being so sweet it attracts too many insects.
Distilled water may be used instead of tap water. However, some researchers are concerned that distilled water lacks minerals that hummingbirds need, and believe it would be prudent to add a pinch of sodium-free salt, which contain potassium chloride, to feeder solutions made with distilled or demineralized water. This should help bring the salt content of artificial nectar back in line with that of natural nectar and help prevent electrolyte deficiencies. Do not use table salt (sodium chloride). Adding salt is not necessary if well or tap water is used.
