It still seems to be working pretty well. I did redo the one baffle halo and it now has one less wire on it. I have one male sparrow that sometimes gets on there now, but that is it. One day I saw four goldfinches on the feeder, which I haven't seen going to the feeders in a long time. The house finches and chickadees also are doing well with it. Finally the red-bellied woodpecker is using the suet now too. The food is lasting a lot longer!
I read somewhere that it might be wise to not use the halos during mating and nesting season though, because it won't work as well. They might quickly get accustomed to it so that it won't work as well the rest of the year. Hopefully I won't have many house sparrows nesting either. I made the openings slightly smaller on the few birdhouses I have, and the house sparrows haven't used them since. The chickadees and house wrens still fit through though. It wouldn't be big enough for bluebirds, but I've never seen a one here, only at local forest preserves. We don't have the right habitat for them in our suburban yard.
