Hello Ellen:
Thanks for the comments on Tiritiri Matangi Island birds.
You are absolutely right, my list is "my list" and I can could birds in
zoos or on television if I want. But the ABA rules apply DO APPLY to the
world lists of ABA members who report their list totals to the ABA. For a
list to be ABA compliant, for areas outside the Americas it has to follow
Clements for taxonomy. And rather than maintain various versions for
various lists, my personal lists now conforms to ABA rules, even ABA rules
that I disagree with.
Under ABA rules, I don't think history matters, i.e., I think that
re-introduced birds are under the same criteria as birds introduced where
they never occured before. So, for example, in my opinion, the
"countability" of Trumpeter Swans in the northeast is the same, whether
they occurred here before, Columbus or not.
So, I think that if a species was extirpated from Tiritiri Matangi Island,
then that species would need to be solidly established there (again) to be
"countable" under rules. So, I'd like to know how well established the
birds are on Tiritiri Matangi Island, and for how long.
Thanks!
David
