Blue-eyed cockatoo

The blue-eyed cockatoo (Cacatua ophthalmica) is a large parrot, measuring around 50 cm (20 inches) in length, recognized by its predominantly white plumage, a mobile crest, and a distinctive light blue ring of featherless skin around its eyes. This unique eye-ring is the feature that gives the species its common name. Like other cockatoos, it possesses zygodactyl feet, enabling it to hold objects and bring food to its beak while standing on its other foot, a trait that is relatively unusual among bird species.

Habitat and Distribution

This species is endemic to the lowland forests of New Britain, an island situated east of New Guinea, making it the sole cockatoo species found within the Bismarck Archipelago. Its habitat encompasses primary (untouched) forests, selectively logged areas, and gardened forests managed by indigenous people. While they are not overly particular about tree types for nesting, they are most abundant and active in primary forests. Nests are typically situated in very large trees, often at an average height of 41 meters (135 feet). There is also a suggestion that blue-eyed cockatoos may engage in altitude and seasonal migratory movements throughout the year.

Diet

The diet of the blue-eyed cockatoo is varied, primarily consisting of seeds and nuts. They supplement this with berries, fruits, insects, and their larvae. Their foraging habits are integral to their survival within their forest ecosystems.

Behavior and Pet Qualities

Blue-eyed cockatoos are known for their intelligence and social nature. They are described as demanding but excellent house pets, with some considering them the friendliest and most loving of all cockatoo species. They exhibit engaging household behaviors, such as mimicking their owners, enjoying play, and even playfully lying on their backs. Due to their high level of interaction ability, these birds require significant attention. A lack of adequate interaction can lead to self-mutilation, including feather plucking.

Conservation Status

Initially classified as least concern by the IUCN in 2004, the blue-eyed cockatoo was uplisted to vulnerable in 2008. The primary threats to the species are the rapid clearing of lowland forests for oil plantations, which destroys their nesting sites and impacts breeding success, and the pressures from illegal trade. Trapping methods can be damaging, further contributing to population decline. Unlike some other endemic bird species that can adapt to less dense forest areas, the blue-eyed cockatoo appears to rely heavily on primary forested regions for its survival. As of 2012, the population was estimated to range from 10,000 to 15,000 mature individuals, but this number is unfortunately declining.
