As Andrew Adcock just restated ' a list is a personal thing, do whatever
makes you happiest'. I agree with this . I'm a twitcher.
As a twitcher I tend to be a 'splitter' largely following Schodde's
listings for Australia, but of course have no scientific status in this
forum so when a new bird is called and I see it I tend to tick it and
let the experts argue about it for the next ' n' months or years through
BARC or whatever. It's what turns them on, but I have no intention of
waiting off for their decisions. If they subsequently dismiss a sighting
which I have earlier ticked, it's easy enough to delete it from my
tally. Given the recent results of BARC deliberations published in a
recent Wingspan one could wait as much as five or even eight years for
an answer, and given my present age I may not have that long to wait. (
crosses himself and says ten Hail Marys).

Science is great but who wants to wait ?
All flack gratefully received.

The DNA analysys for sibling species is best done with mitocondrial DNA
as it changes faster..
AS you will know, most DNA is silent (has no know biological function)
and so you can compare mtDNA in the same silent gap for many related
species. It is an oversimplification to say that <x% difference - same
species, >x% different species, but that is the rough idea.

At the risk of getting too technical, how does DNA evidence
prove/disprove whether or not they are the same species? Given that DNA
is just a sequence of genes do they just draw a line 40 genes along the
sequence and declare "if it's the same to here they are the same
species". DNA or otherwise, isn't species level classification a
biological construct based on grouping similarities?
