Gadwall (duck) , male, in full Breeding plumage does his "mating dance" and call for other ducks on a small freshwater inlet in Newfoundland. Other ducks, not being female gadwalls, are not too impressed.

I put this video together because I used to find it difficult to identify a gadwall amongst a flock of female mallards.

Both the male and female gadwall have a white patch at the base of the hind wing. The female mallard has a blue patch in the same place. This is the easiest way to tell them apart particularly at a distance.

Video was taken at Slimbridge WWT in March 2008. Edited in IMovie HD 6.0.4. Filmed on handheld Canon MV880X.
