Unfortunately, I was only able to get some ugly photos of a sleeping duck.

Not much to look at. The Tufted Duck is the dark one in the middle, flanked by a female (left) and male (right) Ring-necked Duck. Notice how dark the bird is compared to the female Ring-necked Duck: no white on the face, colder chocolate coloring, etc.
But here's my field sketch and notes.

Sometimes you get great looks and satisfying photos. Other times, not so much. But a great little bird and I'm glad it has stuck around long enough for me to drive over to see it.
