These mallards aren’t in eclipse plumage, but in mid-summer after breeding, the drake molts into a dull, basic plumage, called an eclipse plumage. Drakes in eclipse plumage look like hens, but their bills are yellow, while the hens' bills are orange marked with black. The sexes can be differentiated by their bill colors just as they appear here in their breeding colors.
