  Auckland Islands Merganser - Wikipedia, the free encyclopedia
It was not found in a 1909 search, and a thorough 1972/1973 exploration of possible habitat concluded that it was long extinct (Williams and Weller, 1974).
Subsequent fossil discoveries suggest that this merganser was previously resident on the South Island and Stewart Island in New Zealand.
There exists a short remark mentioning "a merganser" found on Campbell Island in McCormick (1842), but this may just as well refer to the semi-marine Campbell Island Teal which is otherwise missing in his notes: he only mentions the Pacific Black Duck ("a New Zealand species of duck").

Although they are seaducks, most of the mergansers prefer riverine habitats, only Red-breasted Merganser being common on the sea.
Along with the Smew and Hooded Merganser, they are therefore often known as "sawbills".

 PHYLOGENETIC RELATIONSHIPS AND INCIPIENT FLIGHTLESSNESS OF THE EXTINCT AUCKLAND ISLANDS MERGANSER
The Auckland Islands Merganser was not, as claimed by Luther (1967), flightless; individuals were observed in flight by Hutton and Ranfurly (fide Kear and Scarlett 1970).
Although the introduction of exotic predators to the Auckland Islands, notably cats and pigs, posed a significant threat to the endemic birds of the Auckland Islands (Kear and Scarlett 1970), the reduced flight capacity ofM.
Mergansers are capable divers and are largely piscivorous, but unlike several other genera of the Mergini (e.g., Somateria, Melanitta, and Clangula), are strictly foot-propelled divers, i.e., strokes of the feet provide the sole propulsion at submergence and for underwater loco- motion (Townsend 1909; Kelso 1922; Brooks 1945; Humphrey 1957, 1958).

 Extinct birds - Wikipedia, the free encyclopedia
The taxonomy of the elephant birds is not fully resolved; it is almost certain that at least one taxon survived until Recent times, but it is not clear which species the reports refer to, if there were indeed more than one.
Generally believed to have been extinct by 1500, this is the only moa species that according to current knowledge might have survived until later times, possibly as late as the 1830s.
Officially critically endangered, it is known only from two specimens taken on an unspecified island at some date in the late 19th century, probably in 1884 or 1885.

Nice photo Alan, Brazilian Mergansers are very rare and i know a lot of conservation is going on at the moment, so your ID could be correct.

Both are similar, cept the head is dark on the Brazilian and has longer trailing feathers on the back of the head, breast has horizontal bars, Auckland does not as this one shows.
