You could have, if you hadn't put it up before BARC:-)

The big question for the - might be "if a vagrant turns up and BARC
doesn't accept the observation, can I add it to my list?" ;)

It has always struck me as a little strange that a vagrant that
turns up once is added to the list, yet a bird that goes extinct is
removed from the list. Perhaps if a vagrant does not turn up again
for (say) 50 years it should also be removed from the list? There is
also the interesting question of how often does a vagrant have to
come before it ceases to be a vagrant? And - to be really
philosophical - if a vagrant turns up and no-one twitches it then
does it exist???

How long do you have to reside at a place before you are considered
to be part of the population? Do you include tourists and short-
term foreign students? I'm not sure what the average "half-life" of
internment on Christmas Island is. The long-term residents of
Christmas Island are made up of three ethnic groups: Chinese, Malays
and mainland Australians.
Shifting the focus of attention to the birds, would you include all
the vagrants exciting the twitchers in the bird populations of Xmas
and CCK Islands?

Tom,
I heartily agree. You could almost say that birding on Christmas and
Cocos was SE Asian birding for xenophobes, except for the fact that
the population of Cocos is mainly Malay and the population of
Christmas is mainly Middle Eastern, albeit they are banged-up in a
concentration camp
Cheers,

Hi Frank,
I think you are missing the point regarding that comment, as
exciting as
Christmas and Cocos sound (I would love to go birding there!) they
are not
in the same faunal zone as Australia so many birders don't see the
relevance. You may as well go New Caledonia and add those species to
your
'French' list.
Tom
And I remember there was a comment about the possible Short-toed
Eagle in
Victoria being better than the rarities reported on Cocos and
Christmas in
December. Sorry. Not even close!!! I saw 11 new birds for my
Australian
list, and I dipped on two. Even Mike Carter added 9 birds to his
Australian
list.
