I live in Michigan's Upper Peninsula, and an old coworker's rule was: "Put the feeders out after Memorial Day, and bring them in after Labor Day." And that seems to be right on. The hummers I've seen come looking for where the feeders hung the previous year, if I don't have them out yet! And taking them in after Labor Day stops you from worrying about preventing freezing. They seemed to really hit the feeders hard the last couple of weeks in August..wow...Great birds!
