My husband is a hummingbird freak also. I do mix a bit more sugar than called for, probably 2 1/2 cups to 7 cups of water and one cup of ice to cool it down.
I have a well, is that water okay?
I have orioles at the feeders all spring and most of the summer and house finches as long as the feeders are out.
The hummingbirds have been coming in since the first of May, one or two at a time. They come in skinny, stay a day or two until they are fat and are off again.
I think they are black chinned hummers, they look black/dark at the feeder although one came through with a red head.
I just saw my very FIRST bright orange 'Hooded Oriole' and I nearly jumped in the air when I saw it. WOW. I thought it was just migrating but then I saw it AGAIN yesterday. Beautiful bird!
