I will say this in defense of the article- I do not put out hummingbird feeders. never have and never will. I do plant for them and thats where they go to eat. I think that hummingbird products are just there to make money and I won't buy into them. I keep my feeders clean and the area clean and make sure the bird bath is scrubbed. And they use that bath all winter long because it doesn't freeze.
