This is one of the reasons that twitchers keep good records of which
birds they have seen and where, especially if a future split is
possible. There's nothing worse for a twitcher than to learn that a
split has occurred somewhere and that he/she may not have bothered to
look for a particular species or ssp in that area - although I suppose
it gives good reason to go on another twitch.
Hence my recent twitch of the Striated Grasswren (whitei) in the Pilbara
which (may?) be given species status some time in the future, a nice
armchair tick if it happens, - but I did get the Red-legged Crake too.

Indeed splits always pose a bit of a problem for a "lister" - unless you
recorded which subspecies you saw or where you saw it (for a split that
happens on geographic lines with no overlaps) then you may actually have
to admit that you don't know which of the new species you have seen and
thus remove it from your list!
Lumps are much easier to process!
