Black Swedish ducks look like they are wearing tuxedos, with their dark black feathering  and white 'bib' that runs from under the bill to half way down their breast. Swedish ducks also have some white on their wings. 

Swedish are very hardy ducks and good foragers. Drakes will weigh around six pounds. Hens will weigh up to five pounds and will lay mostly white eggs, with the occasional blue or gray tinted egg.
