Hang on Laurie - If a vagrant turns up and no-one twitches it, how might we
know that it was ever there ??
On your second point concerning BARC acceptances ,can those people just
returning from Christmas and Cocos add all those exciting new birds to their
Oz lists straight away without waiting for the submissions to be made to
BARC and for the tedious assessment process to take place ?( I say tedious
because it often takes a long time for a determination). Or might it be OK
for them to add them to their lists because in part those people make up the
BARC committee and know most of their ultimate submissions will be accepted?
My bet is that they have added them already ( as would I if I were among
them).
Hey ! I just checked TP's Totals and there they are !! All added on with
great glee. Hah!, just as I suspected.

Or do you mean "if a vagrant turns up and no-one twitches it, was it
really there?". More to the point, "if a vagrant turns up and no-one
twitches it, does anyone really care?"
The big question for the twitcher might be "if a vagrant turns up and
BARC doesn't accept the observation, can I add it to my list?" ;)
