Mystery duck

FRIDAY AFTERNOON: I picked up this duck an hour ago after getting a call from town. The bird was rescued as a newly hatched duckling in Pinedale this past summer after it had been separated from its mom and siblings.

At first I thought it's a ruddy but that's not right. The eye ring has me baffled. Then maybe redhead, nope, how about lesser scaup? Can't see that either. It's not very large and is obviously a juvenile and may be a female. Not a woodie either. I've even posted a question on David Sibley's facebook page hoping he will see it and be able to give me a positive ID on this duck.

Any thoughts everyone? I'm going to take it to Beck or Alkali and release it on Sunday.

UPDATE: It's now 11 o'clock on Sunday morning and the mystery duck is back in the wild. I drove to Beck Lake and finally decided on a release site. I gently tossed the bird toward the water thinking she'd slowly swim away. NOT! She decided she'd had enough of people and took off flying. I never saw her land. This isn't the best photo but it's all I could get in the nanoseconds she gave me to press the camera button.
