BIRDS SPECIES ESTABLISHED IN WESTERN AUSTRALIA At least twenty seven species of foreign birds have been introduced into the wild in this State. Kookaburra (Dacelo gigas) Many more may have been released, but the details have not been well documented. Eleven species are Kookaburras were acclimatized from the now established, most of them being restricted in Zoological Gardens from 1897 onwards.
