If a zoo doesn't like public comments on Facebook, they shouldn't have a facebook profile. Stupid public, huh? We should all shut up and pay, accept whatever conditions our local zoo provides the animals we see. If public opinion didn't matter, we'd all still be staring at bears in pits.
As for the case of babirusa breeding, this has more to do with the animals they recieved, the captive population is very old and inbred, that isn't the same as providing the right conditions for this species to breed. To suggest that South lakes is somehow above criticism becuase it has been successful with a species of wild pig is particularly naive, and implies that all other collections sitting with non-breeding pairs are somehow providing inferior husbandry to South Lakes.
Don't get me wrong, I love this collection, but I equally love the fact that we live in an age where a decision to show an endangered tiger cub to the public is questioned, rightly or wrongly, the scrutiny is important.
As far as I can tell, noone criticised the decision to hand rear on this thread. I am assuming these were comments made on Facebook. ZSL hand-reared their only (Sumatran) tiger cub of recent decades, he has gone on to be well-socialised enough to mate and father cubs of his own.
