Yellow-crested tends to show more yellow on its cheeks, but this is not a reliable distinction as Sulphur-crested also shows some yellow on the cheeks.īirdLife International. For purposes of field identification, their plumages are essentially identical. In most cases, Yellow-crested is most likely to be confused with Sulphur-crested. IUCN classifies it as critically endangered, following a precipitous decline from having been a common, widespread species in the mid-1900s. There is some variation within and among the natural populations-in particular, bill size seems to vary significantly. ![]() The Yellow-crested Cockatoo comprises somewhere between three and six subspecies (not including “Citron-crested”), each with fragmentary, depleted populations that inhabit isolated islands in eastern Indonesia and adjacent Timor-Leste. Sulphur-crested has been widely introduced and apparently viable populations are established in New Zealand (both North and South Islands), with potentially viable ones in Hong Kong, Singapore, and Taiwan. However, small numbers are kept in captivity elsewhere, and apparent escapees have been reported from other islands in the Bismarck Archipelago (mainly on New Ireland). There are no known introduced populations of Blue-eyed, so it remains mostly isolated within its native range on New Britain. Blue-eyed is named for its characteristic orbital skin coloration, but this distinction is only partly reliable for identification because the “Triton Cockatoo” typically has bluish orbital skin (and northern Australian populations of Sulphur-crested reportedly sometimes show this as well). Blue-eyed’s crest also tends to be a paler shade of yellow than the others, but the shades vary somewhat in all three species. ![]() On four forms the yellow feathers curl up and forward, whereas on Blue-eyed the yellow feathers curl down and backward. All five forms have yellow-and-white crests that consist of a white “shield” at the front with several yellow feathers behind. Blue-eyed differs fundamentally from the others in the shape of its crest. Always pay attention to your cockatoo’s behavior it will help create a stronger bond and keep the bird happier.Blue-eyed Cockatoo. The cockatoo crest helps us understand how the bird is feeling. They sometimes do it for absolutely no reason. Sometimes for no reasonĬockatoos raising crest does not always mean something. All he wants is more attention and affection. If your cockatoo does it, know he loves you and wants you to love him. They raise their crest and make lovely sounds to look gorgeous and appealing. They do it to impress their owners and female cockatoos and grab attention. ![]() To impress othersĬockatoos are very humble and attractive parrots that want to be adored and loved. In worst situations, they can bite with their strong beaks. They make noise if they are approached and are unhappy about it. When cockatoos are aggressive or upset, they raise their crest and puff their body feathers to look bigger. If the predators come closer, they also open their wings for defense and hiss to warn. When they feel any danger approaching them, they raise their crest and scream to alert the flock. And if they are confused, they stand still and stay alert. If that surprise makes them happy, they start shaking their head. If anything surprises them, they raise their head and crest, silently observing the situation. Sometimes they also move their feet and head during excitement. They also raise their crest feathers and shake their tail when interested in something. When cockatoos get excited (either because of their favorite food, place, or music), they raise their crests, shake their head, or move to and fro to express their happiness. ![]()
