It’s a terrible photo (and not exactly on the Chicago River), but here is the answer to one of my earlier questions: my first hooded merganser of the season. An unmistakable bird, with a bright amber eye, he was not at all happy to have me too close. He fled with the three mallards to the middle of the pond.
Now that the cold-weather birds are coming in, I can start bringing my camera with me and take decent photographs with something better than my phone. For example, this red-breasted merganser from the same pond two winters ago. A handsome fellow!
