What a shame that what was an excellent original post has descended into such personal diatribe.
I think BUBO and the people who run it are exactly what i want, well-balanced, pleasant, non-sniping birders who are trying to maximise everyone's personal enjoyment regards listing.
I cannot see how any system can work perfectly for everyone though - one man's own list addition regards a BBRC-determined 'unproven' bird is another man's fraudulent claim or example of cheating. But as many have pointed out, you can only cheat if you are trying to beat someone else (though i accept you may point you are cheating yourself), and a claim of a sighting IMO is only fraudulent if that act is 'intentional deception made for personal gain or to damage another individual'. Again this is subjective, but again in my opinion it may be worth having some sort of indicator highlighting that person wishes to be non-competitive. Perhaps those individuals could then appear on the same lists but that indicator would show. It is very very difficult, and which ever alternative you look at, you can see a downside too.
Someone said that most top listers do not yet use BUBO - in my opinion long may that continue based on the sniping competitive nature of some of them, maybe that's what makes BUBO the best listing site available, and with its creative flair and basic common sense and good customer care, I can only see it going from strength to strength!
Maybe the serious top listers could simply run their own "premier league" of birding listing site - as with it's football counterpart devoid of morality & win at all cost mentality.
I wonder how many people still use logbooks? I accept I do not take notebooks with me, but I write up every birding trip in the Birdwatcher's Logbook (currently on book eleven since 1998 when I started birding). I write up field characteristics and observations of birds I have made a mental note of, at the end of the day. I cannot draw, but by writing things up (anything about a birds plumage or behaviour) I learn a lot and its a good way of jogging the memory about long gone days out including funny mishaps such as leaving books on top of the car and driving off, to being desperate to use the loo on a twitch, to falling aslepp standing up at a twitch due to tiredness. My most embarrassing moment was being in a line of 15 birders at Spurn Point looking for a Rustic Bunting that I dipped ! I was intensely looking through low vegetation at a Little Bunting (which I didnt need), at exactly the same time the other 14 were looking the other way at the Rustic that had simultaneously emerged behind me. As you do, people were saying lovely bird, chuntering as you do quietly. What I hadnt realised was that whilst I was commenting on the Little Bunting, the others were commenting on the Rustic! Only when both birds retreated into vegetation and binoculars were put down did I realise with immense embarrassment, that we had been looking at different birds. Prize ***** I felt I can tell you!
