Wow! What an impressive species they are. They are very high on my wishlist, would love to see them in the wild sometime but I'll settle for a captive one.
@MagicYoung Not normally, no. On the visit when all these pictures were taken, I managed to sneak in because there was a public event going on and so I could walk around without anyone noticing that I wasn't supposed to be there. I'd been once before a couple of years previously (there's good birding in the area around the centre with a birding trail that is open to the public) and wasn't able to get into the centre but could just about see a few things looking over the fence.
