I am interested in whether any of the following animals have extant introduced populations. Please note that I am not referring to reintroductions (e.g. the Western Capercaillie in Scotland). I am also not referring to cases in which a taxon is introduced to a part of its native country where it did not previously exist (e.g. the South Island Takahe on several islands off the North Island of New Zealand).
