Hi, Bob -
Unlike "Common" Scoters, Mandarin Ducks are pretty common in captivity, and
documented escapes are pretty common. Also compared to "Common" Scoters, their
native range is further south and their migrations are much shorter, which
makes them less likely intercontinental vagrants.
The real issue here is whether enough of these escapees have fared well enough
in the wild, and enough have found each other, to be successfully reproducing
outside of captivity.

On the subject of Mandarin Duck it seems to be universally accepted that every
such occurrence is a captive escapee. It isn't on the ABA checklist . But if
one was going to show up in the US Oregon would be a very likely spot.
But it does seem unlikely - see the attached URL which shows that its range is
not very wide nor very far north, and its migratory path is short . There are
no records from Attu since there are no ABA records at all.
It's also highly unlikely that a Common Scoter would ever show up in Oregon.
Hmmmm?
