Observations have been made of the blue-eyed cockatoo in other areas of the forest, but the density of these birds seems to be greatest in the primary forest region. Unlike other bird species endemic to these forests, which may have been able to fare well in less densely forested areas such as "forest gardens", the blue-eyed cockatoo apparently relies on primary forested areas. The traps used often prove to be damaging to the bird, some even consisting of branches covered in glue to capture them. Illegal trade has also caused a market for this species, adding pressure to their decline. This rapid clearing is to be thought to have an effect in the cockatoo's breeding, which would cause a decline in the population. The threat of this species is most likely due to the rapid clearing of lowland forest into oil plantations, in which the blue-eyed cockatoo make its nesting sites. Consequently, it was uplisted to vulnerable in 2008. Initially classified as a species of least concern by the IUCN in 2004, it is suspected to have become much rarer in recent times than was assumed previously. As of 2012, the blue-eyed cockatoo's population ranges from 10,000 mature individuals to 15,000 individuals in general. Psittacine habits also suggest that blue-eyed cockatoos may make altitude and seasonal migratory movements throughout the year. The nests are usually located in very large trees, at an average height of 41 m (135 ft). They are not very particular of the types of trees they choose to nest, but are found more abundantly and actively in primary forests versus gardened forests. Packs of the bird would fly 3,280 feet in the air, resulting in a difficult time catching a sighting of them. In the 1960s, researchers found it difficult to find the majestic bird due to their flight routes they took in these gardened forests. ![]() These low-land forests consist of primary (untouched) forests, selectively logged forests, and gardened forests, or ones tended by indigenous people. The blue-eyed cockatoo is endemic to the lowland forests of New Britain east of New Guinea, and it is the only cockatoo in the Bismarck Archipelago. They are also known to feed on insects and their larvae. The blue eyed cockatoo's diet mainly consists of various seeds and nuts, berries, and fruits. A lack of interaction could result in self-mutilation from the bird, that includes feather plucking. Due to their interaction ability, these pets require quite a bit of attention. Household skills include mimicking owners, laying on the back of loved ones, and their love of play. This bird has been called by some as the friendliest and most loving of all the cockatoo species. The blue-eyed cockatoo reaches full maturity after 4 years and lives an average of 50 years.īlue-eyed cockatoo has been known to make demanding, but great house pets. The blue-eyed cockatoo is easily mistaken for the yellow-crested and sulphur-crested cockatoos, but has a more rounded crest with more white to the frontal part, and a brighter blue eye-ring. Some males have dark brown irises and some females have reddish-brown irises, but this small difference is not always reliable as a gender indicator. ![]() The sexes are very similar in appearance. The blue-eyed cockatoo is a large, about 50-cm-long, mainly white cockatoo with an erectile yellow and white crest, a black beak, dark grey legs, and a light blue rim of featherless skin around each eye, that gives this species its name. ![]()
