Best Black Swan event - black swans are native to New Zealand too

In a conversation yesterday, I was asked whether I has read the book Black Swans by Nassim Nicholas Taleb? Yeah, I replied, and then said: ‘You know, the best Black Swan example to me (probably not in Taleb's book if I recall) is that Black Swans once lived in New Zealand too (and its islands 'Chaptam'), and not only Australia as commonly thought. They went extinct (by the Maori), were reintroduced, but have been found, in recent times, to have flown there on their own. They also have similar genetics.  That's the Black Swan of Black Swans I say.
