Sulphur-crested Cockatoo - Cacatua galerita (Latham, 1790) - is a large white cockatoo with a yellow crest.
They are very curious, intelligent and social birds, which makes them very popular as pets. However, they they require a lot of training and attention, otherwise they may develop mental issues like picking their feathers or scream very loud to attract attention!
Make sure to provide plenty of bird-safe toys as they love to chew on wood and other hard materials. Also make sure the aviary is build from strong materials; they have been reported to chew on soft timber on buildings and outdoor furniture!
Wild birds have a lifespan of 20-40 years but pet birds can be much older - some birds are reported having a lifespan of more than 75 years.
Make sure to quarantine new birds as they are susceptible to Psittacine Beak and Feather Disease (PBFD).
The overall plumage is white with a yellowish color under the wing and tail. The large crest is bright yellow and curves up when not raised or forward when raised. The bill is slate grey; the legs are grey.
The nominate form has a white eye-ring and pale yellow ear coverts; the bases of feathers of cheeks and throat are also pale yellow.

Sulphur-crested Cockatoo look similar to the Yellow-crested Cockatoo (Cacatua sulphurea), but the Yellow-crested is smaller, has a darker blue eye-ring and the crest has a different shape.
Sulphur-crested Cockatoo are found in large numbers in forests or woodlands in Australia, Tasmania, Aru Island, New Guinea and nearby Islands. They avoid arid areas with few threes.
They can also be seen in large numbers in suburban areas of Adelaide, Brisbane, Canberra, Melbourne and Sydney.
In some areas of Australia the Sulphur-crested Cockatoo can be found in such large numbers that they may cause damage to crops and may be considered a pest by local farmers. They are however a protected species under the Australian Commonwealth Law.
Sulphur-crested Cockatoo has been introduced to several other places outside their native regions; in Australia they have been introduced to Perth - outside Australia they have been introduced to e.g. New Zealand, Palau Islands, Micronesia Kai Islands and some islands of Eastern Moluccas in Indonesia.

The main diet should be based on pellets. Add a good mix of seeds and nuts as supplement and various vegetables and fruits.
When the flock seek food on the ground, at least one bird will stay in the threes to watch out for predators.
Wild birds nests in a hollow tree using a bed of wood chips.
A vertical box with the measurement of approx. 40 x 40 x 90 cm is recommended as nest box. The aviary should be at least 4,5 meters long.
