Unknown duck-like birds

These ducks have been seen in Buenos Aires, Argentina.
The first one is probably a juvenile, because of the small size and the feathers, but I have no idea of what it can be.
The second one (2-3 photos) was little, too, but bigger than the previous one, so I don't think it is a juvenile.
What do you think?
Thanks

They're not ducks. They're White-tufted Grebes (at least the two adults are, and the chick looks rather grebe like, so I'd say so too).

2 & 3 are the White-tufted Grebes (Rollandia rolland). About 1 I have no idea.

First is obviously a downy young grebe. If you saw it together with adult White-tufted Grebes in breeding plumage, then I'll bet that it is one of their chicks.

There were some White-winged Coots and some ducks in the lagoon, too. So, I guess you are right.
By the way, these birds looked like Mallard, Domestic Mallard and Domestic Muscovy Duck to me, but Mallards aren't found in Argentina. What do you think they are?

Thanks again

these are domestic mallards, maybe wild ones aren't found in Argentina, but descendants of escaped farmyard stock are.
