Eared Grebes. Look at the bills. Horned has a fairly thick bill that tapers evenly at the tip (and that tip at close range is pale). Eared's is much thinner with an upturn and is black its entire length.
Anyway, this swan threw me for a second. It was just too cold to stand at Tiscornia and so I pulled up to the boat launch at North Lake at Grand Mere. It has a plain black bill without a yellow pip but with a (fairly prominent at some sun angles) salmon gape line. A trumpeter, right?
No such identification problems with male wood ducks.
Some flyby mergs in New Buffalo.
Finally a Red-shouldered that perched nicely along US-12. Somehow it was well into fall before I found one last year.
