Saw this duck last week... Hybrid or weird molting phase mallard?

What do you guys think? Full white front.

  See them quite often in park and golf course ponds.

Chances are its a domestic breed. Not necessarily a hybrid. The swedish breeds have a white bib on the front like that one does. They look like hybrids with the coloration but its standard to the breed(s).

Sent from my space modulator.

Most likely hybrid.  I see drake mallards with a chocolate brown heads instead of green at parks too.

Park duck!  Domestic.

Probably a hybrid.
Come mating season... any hen is fair game for mallards.
We used to raise ducks as kids, and I've seen groups of 6-8 mallard drakes raping every single one of our "pet" ducks.
Female... or male....

Blue Swede, my parents raised them when I was young. I have seen them different times at public parks. People letting their pets go possible?

I was going to say hvidbrystet dansk   or Danish white breasted, a domestic breed.
