Oh, goodness, I love that feeder and everything else! Mine is a plain-Jane clear plastic one with a red base. It holds about a quart and my hummers are now going through that much every week or so. I know I have at least three. They love sparring with each other, and you are right about them being gutsy. When I'm reading on my deck sometimes they will buzz around my head. I tell myself they're just saying hello but they may be saying something else entirely. The standard ratio of plain white granulated sugar to boiled water is 1:4, which I use, but FullClip gives his the strong stuff and they seem to do fine with it. (Well, actually they are apparently addicted! LOL) Boiling kills germs and also gets rid of any chlorine in the water. I mix my sugar in while the water is coming to a boil, and then I just let it sit to cool. I only mix a quart at a time, but could do more and put it in the refrigerator. I haven't had to change the food every few days, but I thoroughly clean the feeder every time I refill it. Mine is not in direct sun which probably helps it not go bad as quickly. Mine hangs from my wide soffit just past the railing on my back deck. I can see it through the glass doors from my chair. I may have to order one like yours, though. It is gorgeous! Hopefully your birds will find it quickly. Sometimes patience is needed at first. Mine seem to return year after year. Like Caver, I keep food out until they stop eating in the fall. The birds will enjoy the bird bath, too. I love watching all "my" birds. If you have regular bird feeders, I've found that squirrels don't like safflower seeds. I like squirrels too but don't want to encourage them to get in my attic again. I love your whole set-up. Lucky little fellas there!
