The species seems to have been susceptible to extinction from the get-go. Its not like humans wiped them out down to a last few flocks. People did over hunt them to be sure, but a species that required flock groups of tens to hundreds of thousands to propagate would seem to me to be living on borrowed time. Attempts to breed them in captivity failed because of the massive numbers that seem to be required. So this effort to reintroduce the population will require quite an effort, they will need a first generation in the tens of thousands at a minimum.
