Ruddyduck, take a chill pill. My waterfowl kills are in the thousands. (not bragging, just a fact) I'm color blind and I have a hell of a time identifying ducks in the air. Sometimes I can't even tell the difference between a drake and a hen mallard unless it's a clear day and the sun is bright. I still keep hunting and if I shoot a limit of hens, I have to quit for the day. Don't be a douche to your fellow hunters.
