No, it was your insistence that the NGS was somehow obligated to pay
attention to the BC RBC that caused this little round. Your aggrieved
response to the little note to tweeters pointing out that Xantu's was
in it as a BC vagrant.

Has it dawned on you yet that the person who posted that little tidbit
was firing a barb in your direction?

At least, I suspect it was intentional.

The whole thing's pretty funny, isn't it?

There's a simple solution - if you're offended that you and the
others on the committee weren't consulted by NGS, don't buy the book.

Unproven assumption: RBC records are accurate.

They're conservative, and hopefully records accepted by the RBC have
a high degree of reliability, but given that only a subset of sightings
are ever reported to RBCs, it is clear that they CAN'T be accurate.

Then, where's the beef?

Totally subjective. If you were to rigorously apply the same standard
of doubt to past records, you'd be weeding out a few, I'm sure. There
must be other vagrant records where it has not been proven beyond a
reasonable doubt (your words) that the bird flew there on its own.

The records can not be accurate, in any objective sense of the word.

Then write and sell your own field guide.

Well, we Americans tend to think that of Canada anyway, don't we :)

It's a field guide. It doesn't purport to be a book of official
records.

Let's put the shoe on the other foot, Michael - when did the RBC get
into the business of telling NGS what it can, or can not, publish?

I think I'm going to buy ten copies of it, too. And I know damned
well that I'll never submit a record to the BC records committee.

Yes, exactly as Hal describes, too - there was a total lack of empirical
evidence. Guessing isn't objective.

Perhaps because one member, at least, seems to feel he is the
sole judge of the definition of "properly"? And makes this clear
in repeated, condescending posts on the subject while making it
crystal clear that the decision was strictly subjective, with no
evidence to suggest anything other than arrival by natural means?

In other words, you voted no because its appearance astonished you.

And I suspect NGS will continue to use a variety of sources when compiling
distribution data, no matter how much you wish them to supplicate themselves
on your front stoop.
