well, i learned from watching them my whole life, but for a beginer i suggest going somplace where you can watch many ducks fly, look at the different sizes, shapes, and wing-beats of the birds, look for colors and other distinguishing features(the pin-tail on a pintail, green-head on a drake mallard) learn to tell ranges as well, for identifying how far away a bird is is one of the toughest parts of duck hunting
