I asked this question a while ago and someone gave me an interesting link. I thaught there were only a few non-mallard species but there is alot!So I was skimming thro story guide to raising ducks and this came to mind. Might be confusing, but worth time to ask.
All common breeds (Pekin, Rouen, Cayuga, Swedes, Runners, ect.,) meaning the ones that have been bred for thousands of years and were heavily domesticated in Eurasia are of Mallard descent. The only domestic breed that isn't descended from Mallards are their close cousins, Muscovies. There are many other duck species, but they aren't considered domestic by most standards. Mallards (and Mallard-descended breeds) can hybridize with Muscovies to produce (an almost always sterile) hybrid, which are called different names depending on which parent is which and the gender of the duck itself. Hope this helps!So I was skimming thro story guide to raising ducks and this came to mind. Might be confusing, but worth time to ask.
Yup! You are right!So, the mallard derived breeds include:
And then the non-mallard(I'm pretty sure these are non-mallard) ducks that I can think of are:
So yes, most domestic ducks are derived from the mallard.
