Cacatua ophthalmica Sclater, 1864 |
The Blue-eyed Cockatoo, Cacatua ophthalmica is a large, up to 50cm long, white cockatoo with an erectile yellow white crest, grey color beak and feet, and a prominent light blue ring of featherless skin around each eye, that gives this species its name.
Both sexes appear very similar. Some males have a dark brown iris and some females have a reddish brown iris, but this small difference may not always be reliable as a gender indicator.
Like all cockatoos and many parrots, the Blue-eyed Cockatoo can use one of its zygodactyl feet to hold objects and to bring food to its beak whilst standing on the other foot; nevertheless, amongst bird species as a whole this is relatively unusual. They pair for life.
The Blue-eyed Cockatoo is distributed and endemic to lowland and hill forests of New Britain in Papua New Guinea, and it is the only cockatoo in the Bismarck Archipelago. A common species throughout its range, the Blue-eyed Cockatoo is evaluated as Least Concern on IUCN Red List of Threatened Species.
