Dear Richard,
First of all, I am not agitated, I am perhaps a bit fanatic. Keep in mind, we are on the bird paleontology subforum, here we discuss fossil birds, recently extinct but also extinct longer ago. We also discuss lists of fossil birds, as you have noticed. All I have done is give Markus some suggestions for his list. He seems to like them. Some people, like you and Nutcracker have arguments why they want to draw a line at a certain year. All I try to do is try to show that these arguments are weak and unnecessary and make the resulting list very incomplete and not very helpfull to amateur and proffesional ornithologists. And for Tommy Tyrberg, a member of Markus´ committee, he knows far more about fossil birds than I do and is well able to make such a list.`
You wrote: “The fact is, like it or not, that the four popular world checklists summarise the classification, distribution and common names of birds known in recent/modern times. I'm sure that the vast majority of users prefer it that way, and wouldn't want the lists to be cluttered by large numbers of long-extinct taxa (which could anyway only provide a very incomplete picture, riddled with question marks), and with range statements complicated by the inclusion of much earlier historical distributions”.
Markus is trying to make a list of extinct birds not included in the IOC list, that means Holocene birds extinct birds before 1500.
I’ve tried to show that you end up with two lists, not knowing which species is on which list, not a very senseble thing to do.
While he’s busy I gave him some suggestions how to make the list even more interesting, what is wrong with that?
But as always, if somebody is thinking aloud, other people try to shut him up.
So stop trying to think of reasons why this list should not be made, but of reasons and ways how to realize such a list! Birds unfortunately did not start in 1500 and did not go extinct before 1500! and people have the right to be informed as completely as possible.
It is about scientific correctness and people should care about that.
And before you say it, I am not angry, 'wrong', and 'nonsense!' are not strong terms, they are as far as I know normal English wiords, it is not my intend to hurt anybody with my words, but I have to give my (in my opinion strong) arguments to support my view.
All the best,
Fred Ruhe
