South Georgia Pintail vs Mallard: common questions
Which one eats carrion, unlike most ducks?

Which one is the ancestor of domestic duck breeds?
The mallard holds this distinction, being the wild ancestor of nearly every domestic duck breed, a role the geographically isolated South Georgia pintail does not share.
Which one has the more restricted range?
The South Georgia pintail has the far more restricted range, confined to a single sub-Antarctic island group, while the mallard is found across nearly the entire Northern Hemisphere and beyond.
