The inspiration for the image of Daffy Duck, of Disney fame, is probably a Black Swedish duck (Anas platyrhynchos domesticus) - the only difference is that Daffy has white on his neck and a Black Swedish has white bib on its chest. Swedish Ducks are one of the heartiest of all the breeds, with a calm disposition and are active foragers. Their body type is very close to the Pekin duck with carriage being a little more upright. They will hatch their own eggs if allowed to, and they are plentiful layers. They also have a striking visual appeal. When two Black Swedish breed, they breed true to colour and the ducklings are also black.
