Blue-eyed Cockatoo

The Blue-eyed Cockatoo, Cacatua ophthalmica, presents a striking figure with its predominantly white plumage, contrasting black beak, and the distinctive light blue periophthalmic ring. This large bird, reaching about 50 cm in length, is adorned with a mobile crest of yellow and white, and stands on dark grey legs. Both sexes appear similar, though subtle differences in iris coloration may be observed.

Identification Tips

Distinguishing the Blue-eyed Cockatoo can be a delightful challenge for the avid birdwatcher. Look for its rounded crest with a pronounced white frontal part, and the vibrant blue eye-ring that sets it apart from its relatives, the Yellow-crested and Sulphur-crested Cockatoos. Mature at 4 years, these birds can grace the skies for an average of 50 years.

Habitat

The Blue-eyed Cockatoo is endemic to the lowland forests of New Britain, east of New Guinea, within the Bismarck Archipelago. It thrives in a variety of forest types, from untouched primary forests to those altered by selective logging and indigenous gardening practices.

Distribution

This species is known for its elusive flight patterns, often soaring at altitudes of 3,280 feet, making sightings a rare treat. Nesting typically occurs in large trees at impressive heights, averaging 41 meters above the forest floor.

Behaviour

The Blue-eyed Cockatoo exhibits a strong preference for primary forests, although it has been observed in other forested areas. It may undertake altitudinal and seasonal migrations, a behavior consistent with other psittacine birds.

Diet and Feeding

A diet rich in variety, the Blue-eyed Cockatoo feasts on seeds, nuts, berries, and fruits, and will also consume insects and their larvae to supplement its nutritional needs.

Conservation Status

Once considered of least concern, the Blue-eyed Cockatoo's status has shifted to vulnerable due to habitat loss and illegal trade. The rapid conversion of lowland forests to oil palm plantations poses a significant threat to their nesting sites and, consequently, their breeding success. The population, estimated between 10,000 to 15,000 individuals, is on a decline, with conservation efforts becoming increasingly critical for this species' survival.
