Citron-crested cockatoo : ウィキペディア英語版 | Citron-crested cockatoo
The citron-crested cockatoo (''Cacatua sulphurea citrinocristata'') is a medium-sized cockatoo with an orange crest, dark grey beak, pale orange ear patches, and strong feet and claws. The underside of the larger wing and tail feathers have a pale yellow colour. The eye colour ranges from brown through very dark brown to black. Both sexes are similar. The smallest of the yellow-crested cockatoo subspecies, it is endemic to Sumba in the Lesser Sunda Islands in Indonesia. The diet consists mainly of seeds, buds, fruits, nuts and herbaceous plants. ==Conservation status== The citron-crested cockatoo is an 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.〔 Together with the other subspecies of the yellow-crested cockatoo, it is listed in appendix I of the CITES list.〔 Consequently, international trade is strongly regulated and trade in wild caught citron-crested cockatoos is illegal.
