I have never seen a bluebird in the area of southeast Michigan. Do they even reside here? I get my fair share of the starlings, grackles, pigeons, but also chickadees, cardinals, finches, sparrows, woodpeckers, robins, hummingbirds, red-wing blackbirds. I have never seen orioles, either. I've seen the feeders to attract them, but I doubt any would come. Any information would be appreciated. Thank you.
