Interesting and complicated plurals. I do really like Platipi, but perhaps Platipus is easier. Anyway, we saw two and were later told by the owner of the vineyard that they had had babies, but we did not see those. The owner of the vineyard was a very interesting character. Eric Purbrick was in his 80s, his grandson was really running it, but he liked to talk to visitors and as we were studying wine with the Wine and Spirit Education Trust, he took us on a guided tour, explained all his vinification processes, opened some serious wines for us to taste and in the end gave us a book on the history of the vineyard which he signed. Fabulous afternoon.
Sorry TerryJ this has got well off-topic and I am the main culprit.
