Tanimbar Corella
Cacatua goffiniana
Small white parrot with short crest, ring of grayish-blue skin around the eye, and pink patch between the eye and the bill. Yellow-tinged undersides of wings and tail often visible in flight. Endemic to the forests of the Indonesian Tanimbar Islands, where now uncommon and declining. Introduced populations are scattered widely around the world and have become established in suburban areas in Taiwan, Singapore, Puerto Rico, Indonesia's Kai Islands, and Japan.
识别特征
Tanimbar corellas weigh, on average, about 250 g (9 oz) for females and 300 g (11 oz) for males. They are about 31 cm (12 in) from head to tail.<p>Like all members of the family Cacatuidae, the Tanimbar corella is crested, meaning it has a collection of feathers on its head that it can raise or lower. Its body is mainly covered with white feathers, with salmon or pink colored feathers between the beak and eyes. The deeper (proximal) parts of the crest feathers and neck feathers are also a salmon color, but the coloration here is hidden by the white color of the more superficial (distal) areas of these feathers. The underside of its wing and tail feathers exhibit a yellowish tinge. The beak is pale grey and the eye colour is brown in females and black in males. The males are slightly larger, but otherwise look similar to the females.<p>In captivity, Tanimbar corellas live up to 30 years, making them one of the shorter-lived cockatoo species.

保护状况
Due to ongoing habitat loss on Tanimbar, limited range and illegal hunting, the Tanimbar corella is evaluated as Near Threatened on the IUCN Red List of Threatened Species. It is listed on Appendix I of CITES. In the 1970s, Japanese loggers ravaged the islands. Many of the dazed, disoriented birds were captured for the pet trade. Although many died from stress during shipment, there may be a small silver lining behind this ecological disaster, because many Tanimbar corellas have reproduced in captive breeding programs. As such, there are now more Tanimbar corellas in captivity than in the wild.[citation needed]

Ocellated Woodcreeper
Xiphorhynchus ocellatus
A medium-sized woodcreeper, found primarily in western Amazonia, south of the Amazon river. Lacks any truly distinctive visual features. Shows variable buffy streaking on head, back, and breast, and a scaly buffy throat. Bill is rather straight and typically dark grayish or silvery. Most easily identified by voice, a descending series of rather nasal notes, sometimes with a stuttered pattern. Typically seen singly or in pairs, often accompanying mixed-species flocks in the understory or mid-levels. Occurs in the lowlands and into the foothills of the Andes, usually in mature forest.
Kurrichane Thrush
Turdus libonyana
A gray-olive thrush with a white belly, buff-orange flanks, a distinctive bright orange bill and eye-ring, and a pale throat with a broad black moustache. Pairs occupy a variety of broadleaf woodland, thornveld, and open savanna, where it runs on the ground foraging for plant and animal matter. It gives a series of varied fluting notes and whistles, and is known to imitate the calls of other birds. The similar African Thrush also has a pale belly and occupies savanna, but its bill is yellow, not orange.
Nubian Nightjar
Caprimulgus nubicus
Small and compact nightjar of vegetated semi-desert habitats. Overall rather pale sandy-brown, but note the distinctive rusty hind-collar and buff tips on scapulars and coverts when sitting on the ground. In flight flashes big white patches on wings and tail corners and wings appear relatively short and rounded. Also note the rich rusty underwing. Breeds under bushes, forages in open habitats, and often sits on tracks in the road. Vocalizations sound similar to a distant double-bark, "Kau-kau, kau-kau…"
