I expect Arnoud to follow the broadest possible definition of Cat C, but all of them have (or in case of the culled House Crow: had) self-sustaining populations, so I actually agree – not something I say everyday, haha!
Two of them would be "C5" when using the UK categories: the Chilean Flamingos from the Zwillbrocker Venn winter in Zeeland; Sacred Ibises from western France have occurred in the Netherlands.
Not sure Arnoud really thinks of this list as having to meet any definition of Cat C... (And, indeed, the definition currently used in Belgium is probably one of the strictest possible. Note Mandarin is not on the list... Not that I really care, btw.)
Chilean (and European) Flamingos from the ZV have occurred in Belgium as well but these are treated here (both spp) as escapes (Cat E). (We would need the population to be in Cat C in the country where it breeds to accept it as such here. It's not.)
