Many thanks for the comments. Jack, thanks also for the comment about my website. I'm actually in the process of migrating it to a new host in the hopes of speeding up the viewing experience, so it may disappear for a few days while the changes propagate.
Dave, I got pretty lucky when I found that last bit of open water. A week earlier the entire lake was frozen and covered in a layer of snow, so the lake just looked like a big, snowy meadow. Then the temperatures rose above freezing for a while, and now the ducks have some room to paddle around again. There is a larger area of open water in the distance, and it was full of ducks. I was very lucky that they didn't decide to inhabit *my* opening instead because that would have spoiled the reflection. Anyway, as with most shots, this one resulted from a happy combination of planning and luck.
