They are diurnal, active during the day, and roost in large groups at night. In terms of behavior, cockatoos are social and intelligent birds, known for their loud calls and playful nature. These birds require large territories for foraging and are often seen in flocks, especially in regions where food is abundant. Some species, like the Galah and the Sulphur-crested Cockatoo, have adapted well to urban environments. Their habitats are diverse, ranging from rainforests and mangroves to open woodlands and mountain forests. Habitat and DistributionĬockatoos are native primarily to Australasia, including Australia, Indonesia, Papua New Guinea, and some Pacific islands. Sexual dimorphism is present in many species, often visible in eye color differences males typically have darker eyes compared to females. They possess strong, curved beaks designed for cracking nuts and seeds, and zygodactyl feet (two toes facing forward and two backward) ideal for climbing and grasping. The sizes range from the relatively small Cockatiel, measuring around 12 inches in length, to the larger species like the Umbrella Cockatoo, which can reach up to 24 inches. Their coloration varies widely among species: from the predominantly white Sulphur-crested Cockatoo with its iconic yellow crest to the deep black of the Red-tailed Black Cockatoo, adorned with vibrant red tail feathers. They typically exhibit a striking crest of feathers on top of their heads, which they can raise or lower. Sulphur-crested Cockatoo DescriptionĬockatoos are renowned for their distinctive physical appearance. Subspecies variations often involve slight differences in size, feather patterning, and habitat preferences. For instance, the Sulphur-crested cockatoo is known for its bright yellow crest and white plumage, while the Major Mitchell’s boasts a multi-colored crest and a more nuanced color palette. Key differences among these species include size, coloration, and crest shape. The Red-tailed Black Cockatoo ( Calyptorhynchus banksii) and the Palm Cockatoo ( Probosciger aterrimus) are other notable species. The smaller cockatoos, like the Cockatiel ( Nymphicus hollandicus), belong to different genera. The genus Cacatua includes the larger cockatoos like the Sulphur-crested ( Cacatua galerita) and the Major Mitchell’s Cockatoo ( Cacatua leadbeateri). Least Concern to Critically Endangered ( IUCN Red List)Ĭockatoos are classified into several species and subspecies, each with distinct characteristics.
