Who would be the ‘Zorro’ ducks?

If someone referred to 'Zorro' ducks, would they mean the Silver Teal? Also known as the Versicolor Teal, this attractive little duck is widely distributed in South America. Or maybe it would be the much bigger Puna Teal, once considered conspecific with its aforementioned cousin with which it also differs by always lacking yellow on its relatively long bill. We have recently added both of these species to our ID section.
