The breeding distribution of this species (feral birds and their offspring) was never recorded before but may have been slightly underestimated. The species is most abundant in the lowlands, especially in and around urban habitat. The number of breeding pairs is difficult to quantify, perhaps some 3000-4000. An additional 4000-6000 non-breeders do occur.
