Duck ID challenge

There is a photograph of a small flock of ducks on page 7 of the winter edition of Kites Tales. Can you identify them? The answers are at the end of this post.

Can you identify these ducks?

Thanks to everyone who took part in the duck identification challenge. Many of you got one or two of the three species in the picture, but only one person got all three. Well done Jason Guerard! There are 5 ducks in the picture. There is a male American Wigeon  at the top of the picture and a female Northern Pintail below him. There are 2 female American Wigeon bunched in tight, below and behind the pintail, and there is a male Gadwall tagging along below them and to the rear.
