Hooded Merganser

On Sunday, 30 November, Erika and I hiked in the Minnesota River Valley National Wildlife Refuge from the Bass Ponds to the Old Highway 77 Bridge. On the one open pond swam about a dozen Hooded Mergansers. Because of their pale bills, I believe these birds are hens. Males have darker bills and usually have yellow irises.  The leading bird, because of her more flamboyant crest, is likely an adult. The other merganser is probably an immature. In any event, I found the different water patterns to be intriguing.
