Just reviving an old thread;
It's 50 years ago this month that Taronga had its first black rhino birth, which at the time was a big deal (still is, I suppose) and was reported all over the world.
Thank you for reminding us Ara. I remember the event well but, of course, had not recorded the date. We might have to collaborate on "the book". [Should make Zoo_Boy happy!]
Sir Edward Hallstrom was surely a man ahead of his time in many ways.
