Scorchingly hot weather is upon us in the Pacific Northwest, and it’s understandable to want to feed hummingbirds, but here’s the thing: Hummingbirds have no sense of smell and cannot tell if the sugar water in a feeder has gone bad. Deadly toxins can contaminate a sugar solution rather quickly in very warm weather—as fast as 24 hours—especially if the feeder receives some sunlight. Hummingbirds may become ill (and consequently more subject to predation) and even die from feeding at unattended feeders. And I don’t even want to think about a mother hummingbird’s nestlings who might starve to death after she’s been sickened by fermented sugar water that’s rich in mold and bacteria.
Real flowers are best
To avoid all these potential dangers, I always recommend growing plants (preferably native to your area so that other species benefit as well) that provide natural nectar which contains micronutrients, unlike refined sugar. Besides the nutrition and safety of real nectar, you won’t have to deal with unwelcome insects at feeders. Hummingbirds may also consume a sugary liquid from trees and often forage where woodpeckers called sapsuckers create sapwells from which hummers feed. Keep in mind, too, that these amazing little birds do not live on nectar alone—their diet includes a surprisingly large amount of tiny insects (and spiders) for protein, and the best way to provide that is, again, with native plants (and no pesticides, of course!). And, needless to say, fresh water is essential for all birds.
If you do feel a need to feed hummers via artificial feeders, here’s a handy chart for how often to clean and refill your feeder, courtesy the Wild Bird Shop:
♦ Refill with just the amount of sugar solution that will be consumed in the time period according to the temperature range.
♦ Keep feeders in the shade.
♦ Choose feeders that don’t have tubes or removable parts, which are very difficult to keep clean. I like the HummZinger feeders, which are VERY easy to clean. Rinse well after cleaning with hot soapy water (no bleach).
♦ Stay away from the colored, pre-mixed commercially available solutions—natural nectar is colorless, and adding red dye is adding an unnecessary, unnatural, and possibly harmful chemical to the birds’ food. If your feeder doesn’t have red on it, simply hang a red ribbon next to the feeder.
♦ Only use white cane sugar in a ratio of 4 parts water (preferably filtered, w/o chlorine) to one part sugar. No honey, molasses, or syrups.
