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 color. The eyelid color is a very light blue. Both sexes are similar. Females have a coppered colored eye where as the male has a very dark black eye.
The smallest of the yellow-crested cockatoo subspecies, it is endemic to Sumba in the Lesser Sumba Islands in Indonesia. The diet consists mainly of seeds, buds, fruits, nuts and herbaceous plants.

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.
