There are quite a few of these birds that can still be seen in the bird market in Jakarta. Are they really endangered or like many Indoneian animals species have most of them just moved to Jakarta?

I had the most fascinating telephone discussion with Bonnie Zimmermann, Vice President of the Indonesian Parrot Project, about the recent reported rediscovery of several individuals of the rarest cockatoo in the world. This species, known as the Masakambing (Abbott's) yellow-crested cockatoo, Cacatua sulphurea abbotti, is a subspecies of Yellow (Sulfur)-crested cockatoo, which are endemic to several small islands of Indonesia. Worldwide, five cockatoo species are critically endangered -- four of which are yellow-crested cockatoos that are found only in Indonesia. Last seen more than twenty years ago when the total population numbered between roughly five and ten individuals, these birds have remained enigmatic due to their rarity and to the immediate threat of extinction.
