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!

Hi Keith
He/she would only get the "8 more ticks" if they had seen all 8
populations of the now split species.
This, I would think, would be quite reasonable.

So if a twitcher sees the antbird before it's split, I assume he gets 8
more
ticks in his lounge room the moment the split occurs.
After all, the ticks mean more than the genetics don't they? : )
