I also noticed that I haven't had as much activity with hummers at my feeders. Usually, they seem more active early morning and late evening. Orioles will also feed on sugar water, no color necessary. I also put out oranges for the orioles, and have seen finches, red breasted woodpeckers, and others eating the oranges.Apples also work for most birds,gray catbird, cardinals, finches, rose-breasted grosbeaks.
