The main consideration in captive breeding toward the ultimate goal of reintroduction to the wild should be to have a self-rearing captive population which are acclimatised to the climatic zone in which they are to be ultimately introduced.

Initially, if using at least some intensively reared stock, the priority is to develop a breeding stock of adult birds who consistently feed their young very well for the entire rearing period as fostering and hand-rearing techniques merely serve to inadvertently select against the vital trait of parenting ability. I have seen this in some of our captive stock in Australia where birds from regularly fostered stock will readily nest and lay eggs but fail to properly rear their young as they have been selected to simply produce eggs. These birds do not even attempt to brood the young for the first 9 -10 days after hatching which is vitally important to rearing success in outdoor aviaries. Even those who supplementary hand feed young in nests whilst the parents still feed the young are generally encouraging breeding birds who are poor feeders of young birds as these stocks still regularly produce young birds even with relatively poor parent-feeding of the young. The self-rearing trait is the most vital trait to select a stock of prospective reintroduction flock from.

Cheers,
