In this clip, two American Black Ducks hang around the shoreline of the Sapsucker Woods Pond. American Black Ducks are often confused with female Mallards but have darker bodies overall.

Mallards Dabbling Near Shore on a Rainy Day

These Mallards were seen dabbling (as they do) around the Sapsucker Woods Pond shoreline. Easily recognizable, Mallards are one of the best examples of a sexually dimorphic species, meaning that males and females appear differently from one another. Sexual Dimorphism can manifest in a variety of interesting ways, including differences in color, shape, size and other secondary sexual characteristics. The most striking example in the Mallards' case is the differences in the male and female plumages. For most of the year, the dark green sheen of the head, ringed neck, pale body, and curved central tail feathers set male Mallards apart from their streaky brown female counterparts.
