I agree with the thrust of your statement but differ on interpretation
of one point. If the aim is to record where birds are nowadays, why
does it matter how they got there? If Australian dams become over-run
with say, greylag geese or mallards that are escapees/releases, are
they not there? I think ignoring birds because of their potential
heritage is foolish in the extreme and could ignore valuable data for
tracking trends etc.
