The Citron-crested Cockatoo, Cacatua sulphurea citroncristata, is the smallest of the Greater Sulphur Crested Cockatoos with a orange crest instead of the typical yellow. Pale orange ear patches with yellow among the white body feathers, and yellow under the wings and tail feathers identify this variety.
It is a race of the critically endangered Lesser Sulphur-crested Cockatoo. Origin is in Indonesia, Lesser Sunda Islands and Sumba.
These birds make great pets, but require a lot of attention as with most cockatoos. They are not as noisy as most cockatoos, but are curious and like to chew. They often will hide toys and bits of food under their wings while playing. They are not common in pet stores, but are becoming more common with breeders and are endangered in their place of origin.
