    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).

    -Dromedary (Camelus dromedarius) (outside of Australia)
    -Domestic Bactrian Camel (Camelus bactrianus)
    -Zebu (Bos indicus)
    -Rattus species, excluding R. rattus, R. norvegicus, R. exulans, and R. tanezumi
    -Bamboo Rat species
    -Domestic Guinea Pig (Cavia porcellus)
    -Shrew species, excluding the Asian House Shrew (Suncus murinus)
    -Eurasian Corvus species, excluding the House Crow (Corvus splendens) and Western Rook (Corvus frugilegus frugilegus).
    -Icteridae (under the aforementioned criteria, Hawaii does not count)
    -Macaw species (outside of Florida)
    -Rallidae, excluding the Gough Moorhen (Gallinula comeri) and members of the Porphyrio porphyrio complex.
    -Cygnus species, excluding the Mute Swan (Cygnus olor) and Black Swan (Cygnus atratus)
    -Red Junglefowl (Gallus gallus); i.e. populations derived from the truly wild species and not derived from domestic chickens.
    -Alectoris species, excluding the Chukor (Alectoris chukar) and Red-legged Partridge (Alectoris rufa)
    -Cuculiformes, excluding the Smooth-billed Ani (Crotophaga ani)
    -Tyto species (under the aforementioned criteria, Lord Howe Island and Hawaii do not count)

    Spot-breasted Oriole is introduced in Florida, and Western Meadowlark is introduced in Hawaii.

    There are some truly wild Red Junglefowl on some Hawaiian mountains.

    Are you sure? Do you know where they were imported from, and when?

    They came with the Polynesians. I saw this mentioned in Birds of Hawaii (by the Hawaiian Audubon Society). I will get back to you on where as soon as I find the book on my shelves.

    I visited Gibraltar at the height of the British/Spanish tension when the garrison was at full operation and the Spanish border closed. Contacts in the British military allowed us access to the cave systems and tunnels closed to the public; and onto the Windmill Hill Flats, the southern plateaux of the Rock where there were considerable numbers of (very wild) Barbary Partridges. We were there under the escort of the local ornithological society as this area too was under military restrictions. Much of the flora and fauna on the Rock is of North African origin and has not extended its range over the isthmus onto the Spanish mainland. They considered the Partridge native and not introduced. I think it is the National Bird of Gibraltar.

    Apparently there are wild-type Red Junglefowl introduced in Georgia.

    Wild-type Red Junglefowl are also introduced in Sabah, Borneo.
