. Just because their species isn't specified, it doesn't mean that they shouldn't be including in the match! If they are Australian, which most of them very likely are, then they should be included. I'm not sure why you are arguing about this anyway given the triviality of the situation. You don't need to go nit-picking in a massive species list where there is very likely errors anyway, which didn't even come from me.
The issue is that if you don't know whether a species should be listed or not, the default should not be "the zoo is in Australia so they are probably an Australian species" or similar; for instance, when compiling the list upthread of species relevant to this challenge which are held at Chester, there were quite a few bird species native to mainland Africa or the Lesser Sundas which I omitted for that reason, because although I thought their ranges extended into Madagascar or the Moluccas respectively I wasn't certain. As for your second point; given the fact you did curate the list from Wikipedia to some degree, removing species such as European Rabbit and various domestics, those species which have been erroneously retained cannot be dismissed as outside your control.
Basically, you're doing a good job providing this information - and in point of fact you're one of the few people on the other side of the discussion who has bothered to provide any such information, between this list and your above post showing the tree kangaroo exhibit - but being open to improving the quality of the information provided in the future can only be a good thing
