Back in December(12-13) when I took these pics there were several large flocks of common goldeneye hanging around in the river near Prescott. It sometimes made it difficult to find the harlequin duck, who would often swim with groups of golden eye. this was difficult because the goldeneye and harlequin are about the same size and both are diving ducks so they have similar behavior. As winter continued on the number of goldeneyes that stayed decreased.
I usually tend to stay away from photographing female ducks, let alone posting the pics, because so many different types of female ducks are difficult to identify because they look so similar to females of other types. However since this duck had just captured a huge fish I decided to capture a couple of her images on my camera and now the blog.
I believe that it is a mallard but since the mallard is a dabbling duck, as compared to a diving duck, it would be lot less likely to be eating a large fish. As a dabbler mallards typically eat aquatic vegetation as well as insects and invertebrates although a little extra protein during the winter is nothing to turn your beak on. It is very possible that the fish was already dead when the mallard found it. Either way as soon as she got the fish lined up correctly in her bill she tipped her head back and ate it whole.
