Blue-eyed Cockatoo
Cacatua ophthalmica
A large, bulky white parrot with a tall yellow-and-white crest that it often raises when perched and bright blue skin around the eyes. In flight, underwing and undertail washed yellowish. Prefers lowland tropical forest up to 100 meters of elevation. Often common around villages at the forest edge. Unique within its range. Voice loud and obtrusive, including a screaming and gull-like “rehhhhh rehhhhh.”
识别特征
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. The sexes are very similar in appearance. 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 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. The blue-eyed cockatoo reaches full maturity after 4 years and lives an average of 50 years.<p>Blue-eyed cockatoo has been known to make demanding, but great house pets. This bird has been called by some as the friendliest and most loving of all the cockatoo species. Household skills include mimicking owners, laying on the back of loved ones, and their love of play. Due to their interaction ability, these pets require quite a bit of attention. A lack of interaction could result in self-mutilation from the bird, that includes feather plucking.

分布与栖息地
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. These low-land forests consist of primary (untouched) forests, selectively logged forests, and gardened forests, or ones tended by indigenous people. In the 1960s, researchers found it difficult to find the majestic bird due to their flight routes they took in these gardened forests. Packs of the bird would fly 3,280 feet in the air, resulting in a difficult time catching a sighting of them. 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. The nests are usually located in very large trees, at an average height of 41 m (135 ft). Psittacine habits also suggest that blue-eyed cockatoos may make altitude and seasonal migratory movements throughout the year. As of 2012, the blue-eyed cockatoo's population ranges from 10,000 mature individuals to 15,000 individuals in general. This population, however, is declining.

Naretha Bluebonnet
Northiella narethae
Brown parrot with yellow belly, red undertail, and blue face, found in dry woodland habitats of the extreme southeastern part of Western Australia, on the western fringe of the Nullarbor Plain. In flight, the blue wings and red shoulders contrast with pale brown back; lacks the bright green back of other desert parrots. Identify from the very similar Greater Bluebonnet by a completely yellow belly and also by range.
Andaman Masked-Owl
Tyto deroepstorffi
A medium-sized owl with a prominent facial disc. Very similar to the Barn Owl, but the Andaman Masked-Owl is smaller and much browner overall, with darker upperparts and heavily spotted pale brown underparts. Found around forest edges, farms, and habitations. The call is a short but loud dry screech.
Brown-breasted Kingfisher
Halcyon gularis
A fairly large kingfisher of lowland and foothill open country and forest edge. Chocolate brown on the underparts and hood, down to the upper back. Back, tail, and wings bright blue, with large black shoulder patches, small black wingtips, a white throat, and a bright red bill and legs. Somewhat similar to Stork-billed Kingfisher, but Brown-breasted has chocolate brown rather than orange underparts. Song is a rapid, descending series of a dozen or so sharp notes, trailing off in volume.
