The citron-crested cockatoo is a critically endangered bird whose population has declined due to habitat loss and illegal trapping for the cage-bird trade. A 1993 survey of Sumba estimated the species' numbers at less than 2,000 individuals.[1] By 2012, the estimate had dropped to 563.[2] Together with the other subspecies of the yellow-crested cockatoo, it is listed in appendix I of the CITES list.[3] Consequently, international trade is strongly regulated and trade in wild caught citron-crested cockatoos is illegal.
