Here is an
article by
Penny Elliston, a licensed hummingbird rehabilitator, about the dangers of relying too heavily on commercial mixes.
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 the 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.
