Not during winter hunting season. Drakes get full plumage and the blue bill later in the spring. This is winter plumage, drake and hen. Super tiny birds fun to shoot.
You may consider the ident-I-cards. They are waterproof 4x6 cards for hunters to ID ducks. I don't believe anyone who's identifying birds in flight with their light behind the bird early in the morning or late in the evening. The sharp angle of the light prevents most humans from quick color identification. That said there are many birds I ID by their profile, flight pattern and definitely noise before light is defused and colors are discernible.
I saw black scoters on the OH river towards the end of the season. They were just flying past me. I had a shot but never raised my gun because I didn't recognize them.
