It is a question of statistics. Can anyone tell us what percentage of birds
are flagged? (And as an accurate statistic - not a wild guess.) If it a
small number, and most flagged birds are not observed again, this means
nothing - you are simply flagging birds which will not be seen again
anyway - or not by the small percentage of birders who report it. If it is
most birds (> 60%), which I doubt, then we probably should stop flagging if
they are not seen again.

I await accurate statistics.
