They often feed in large flocks, particularly when ground-feeding. The second and larger branch is formed by the genus Cacatua, comprising 11 species of white-plumaged cockatoos and four monotypic genera that branched off earlier namely the pink and white Major Mitchell's cockatoo, the pink and grey galah, the mainly grey gang-gang cockatoo and the large black-plumaged palm cockatoo.Ĭockatoos prefer to eat seeds, tubers, corms, fruit, flowers and insects. The five large black-coloured cockatoos of the genus Calyptorhynchus form one branch. The remaining species are in two main clades. The phylogenetic position of the cockatiel remains unresolved, except that it is one of the earliest offshoots of the cockatoo lineage. On average they are larger than other parrots however, the cockatiel, the smallest cockatoo species, is a small bird. Their plumage is generally less colourful than that of other parrots, being mainly white, grey or black and often with coloured features in the crest, cheeks or tail. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia.Ĭockatoos are recognisable by the prominent crests and curved bills. Along with the Psittacoidea ( true parrots) and the Strigopoidea (large New Zealand parrots), they make up the order Psittaciformes. This species is listed as Least Concern by IUCN and under Cites Appendix 11.A cockatoo is any of the 21 species of parrots belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. It is no longer legal to import this bird into the United States, according to the Wild Bird Conservation Act.
Sulphur-crested cockatoos can live up to 100 years in captivity. This species’ average lifespan in the wild is forty years. If a predator is detected, they let out a deafening warning call. Large groups of birds will feed on the ground with sentinel birds in high trees taking turns acting as lookouts for predators. They are also intelligent and very curious. They are very noisy birds, with a loud raucous call that can be heard for long distances. Even though they may travel long distances to forage, they return to the same roosting area at night. These birds are most active immediately following sunrise. Little information is known about mating in areas other than Australia. The young fledglings will remain with their parents for a number of months after fledging. Incubation of their clutch of two to three eggs lasts from twenty-five to twenty-seven days, with both parents sharing incubation duties and raising the nestlings for the next nine to twelve weeks. Typically a bed of wood chips makes up their nest. This species competes with other birds for nesting sites generally in a high tree hollow. The birds typically preen each other’s feathers prior to mating.
The courtship ritual includes crest raising, head bobbing, and moving the head from side to side in a figure eight pattern while uttering soft chattering sounds. In northern Australia the breeding season is from May to September, and in southern Australia from August to January. This species reaches reproductive maturity at three to four years of age and breeds once a year in Australia. They will also eat newly planted and ripening grain crops.
These birds will feed on the ground and in trees, eating mainly nuts, fruits, seeds, blossoms, insects, and insect larvae. Sulpher-crested cockatoos are 18 to 20 inches tall (45 to 50 centimeters). Males have darker brown eyes and females have red tinted brown eyes. Males and females are similar in appearance. Its feathers are pale yellow under the wings and on the tail. This large white bird has a distinctive sulphur yellow-colored crest that may be erected or folded down on the top of their head. It can also be found in urban and suburban areas in parks and gardens. Sulphur-crested cockatoos live in tropical and subtropical rainforests and savanna areas. It has been introduced in New Zealand, Palau, and Singapore. This species is found in Australia, Tasmania, New Guinea, and nearby islands. The Aquarium’s sulphur-crested cockatoo Lola (a male) is one of the ambassador animals that participate in meet-and-greets at various locations around the Aquarium, including regular appearances at the Pacific Visions entrance.
