It's not so much a debate as a discussion, though it has gone off topic a bit. 
I don't think anyone suggested that Ibis were anything good or bad but the 
increase in numbers would seem to be indicative of a wider problem, that is 
causing the decline of many other species (a fact that we would probably agree 
is a bad thing). It seems abundantly clear to me that access to more / better 
quality food is causing the increase and since the birds feed in farmland, this 
would suggest an expanding monoculture. Are there any farmers on birding-aus 
who can shed light on possible reasons for this?
