Female mallard or close relative. Actually I gave up waterfowl hunting because I couldn't tell the legals from the illegals. :)
Great Photos! I used to go duck hunting years ago but I would much rather look at pictures of them than shoot nowadays. And it a lot warmer :-)~Ron
Looks like a female mallard to me. Nice photo.
Those are great shots. I just put up some owl shots last night, my first ever!
Whatever she is she has lovely blue feathers.
