I love the window above my desk, which looks out onto the backyard -- and more specifically, two of our bird feeders. In the last 10 minutes I've seen a male cardinal, goldfinches, a nuthatch, various other finches (including perhaps a red finch, or house finch? My daughter is much better at identifying these), and a European starling. We also have attracted catbirds, mourning doves, robins (of course!), many woodpeckers and a couple of days ago we caught a glimpse of a blue jay. In fact, we have a bird identification guide, and we try to mark off the birds we've seen in the yard.
What unique birds do you attract to your yard, and how do you do it?
