The Citron-crested Cockatoo, Cacatua sulphurea citrinocristata, is a medium-sized cockatoo prevalent to Sumba and Lesser Sunda Islands in Indonesia. The Citron-crested Cockatoo is classified as an endangered species. Its numbers in the wild have declined due to habitat loss and illegal trapping for the cage-bird trade.
This bird has an orange crest, dark gray beak, pale orange ear patches, and strong feet and claws. The undersides of the larger wing and tail feathers have a pale yellow color. The eye color ranges from brown through very dark brown to black. Both sexes are similar. The diet consists mainly of seeds, buds, fruits, nuts and herbaceous plants.
Citron-crested Cockatoos can make good pets, as they are friendly and sociable. They are not as noisy as most cockatoos, but are curious and like to chew. Generally they are quiet, but they can make a moderately loud honking or screeching sound. They can also make a repetitive quieter whistling or squeaking noise. They are not good at imitating human speech as some members of the parrot family, having a vocabulary of up to only 15 words or phrases. They readily learn tricks and they can be trained. They often raise the colored crest feathers in display or when surprised.
