Keith,

I "give a shit what Rare Birds Committees think"! I can't speak for BARC. 
However, in my "American life" I was a member of the New Jersey Rare Birds 
Committee (NJBRC, the New Jersey counterpart of BARC) and in my "German life" I 
was a member of the Hessen Rare Birds Committee (AKH) and the 
Schleswig-Holstein Rare Birds Committee (AKSH) (two German counterparts of 
BARC). The idea of Rare Birds Committees is NOT to 'kill' a tick on someone's 
'list'. No, the most important job of Rare Birds Committees is to peer review 
the documentation of a 'rare bird' (reports and photos, sketches, sound 
recordings - or whatever you submit), to collect, publish, and archive the 
records that prove that a 'rare bird' occurred. Therefore, documentation must 
eliminate any other species that might be confused with the claimed rarity. 
Some documentation is clear cut, such as a good photograph which shows 
identification characters. Some documentation is less clear cut, and that's why 
there is a large committee with a variety of specialties, opinions,
 and skills to vote on the evidence. To learn about recent range expansions of 
certain species it is also important to get an idea if a bird came on its own 
or was released by someone.
Serious scientific journals only use data that were accepted by the responsible 
Rare Birds Committee for their analysis. That's why I'd like to encourage 
observers of a 'rarity' to document it, so that it can be used for scientific 
studies.

Cheers,

Nikolas

Well it's a bird and at least it's in the geographical confines of what most
of us think of as "Australia".

Who really gives a shit what BARC thinks anyway? More interested in weird
vagrants found in territorial waters than anything mere mortals could hope
to twitch.
