In the message from Pairi Daiza they talk about the Eudyptes chrysocome filholi. This species would according to Zootierliste not be kept in Europe. So I assumed that this was a mistake.
Then I suddenly remembered a text from the 2019 EAZA TAG Reports. It said: "As long as a proper taxonomy of the (sub) species of rockhoppers is not in place, a tiny population of Eastern rockhoppers (E. chrysocome filholi) in one facility will still be kept separate from the others."
So it could well be that these are the E. c. filholi. That would mean that the other animals are at Marineland. The three birds in Pairi Daiza came from three different couples, so Marineland would have at least six animals.
No, these are the same as all others in Europe. I’m not sure where the filholi are but it’s not Antibes.
