Oriental Stork
Ciconia boyciana
Endangered stork of expansive wetlands and fields in East Asia. Adult white with sharply contrasting black flight feathers, black bill, and red legs; juvenile similar but orange-billed. Compare very different Siberian Crane, with shorter bill, black restricted to outer portion of wing. Stately, elegant bird in flight and on ground, where it forages for grain, fruit, invertebrates, and small animals. Breeding display involves loud clattering of bills, but typically silent.
识别特征
It is typically larger than the white stork, at 100–129 cm (39.5–51 in) long, 110–150 cm (43–59 in) tall, a weight of 2.8–5.9 kg (6.2–13.0 lb) and a wingspan of 2.22 m (7.3 ft). Unlike its more widespread cousin, the Oriental stork has red skin around its eye, with a whitish iris and black bill. Both sexes are similar. The female is slightly smaller than male. The young are white with orange bills.
分类信息
The species was first described by Robert Swinhoe in 1873. It is closely related to and resembles the European white stork (C. ciconia), of which it was formerly often treated as a subspecies.

分布与栖息地
The Oriental stork is found in Japan, China, Korea and Siberia. It was once extirpated from Japan and the Korean Peninsula. However, in May 2007 a hatchling was reported in Japan for the first time in 40 years in the wild. It was an offspring of two storks who were bred in captivity.

保护状况
Due to habitat loss and overhunting, the Oriental stork is classified as endangered on the IUCN Red List of Threatened Species. It is listed on Appendix I of CITES.There have been efforts to reintroduce the storks to the wild, but there must be changes to the environment first. The storks were harshly impacted by the growth of the rice industry and the subsequent use of pesticides. There is a push for rice farmers to grow their plants organically so that the storks may breed and grow safely in their environments.

其他鸟类
Greater Yellow-headed Vulture
Cathartes melambrotus
Widespread and common vulture in lowland rainforest. Head may not appear yellow unless seen at close range. Best identified by steady flight with wings held at a slight dihedral. Similar to Turkey Vulture, but has broader wings which it holds flatter and does not teeter from side to side as often. Occurs in rainforest, cities, and agricultural areas.
Zoe's Imperial-Pigeon
Ducula zoeae
A large pigeon of lowland and foothill forest. Pale gray head, yellow eye and short green tail. Pale pinkish breast and whiteish belly are divided by a distinctive thin, black breast band. Fairly common but not seen too often as it keeps more to the forest interior. Distinguished from all other imperial-pigeons by chest band. Its distinctive call betrays its presence. A long, muffled note followed by a series of chuckles “wooo wuhuhuhu wuhuhuhu”.
Sandwich Tern
Thalasseus sandvicensis
Pale medium-sized tern with a geographically variable bill pattern: black with a distinct yellow tip in most of its range; entirely yellow in the Caribbean and parts of South America. Shows a shaggy black cap in breeding plumage; nonbreeding birds develop white forehead. Strictly coastal; most commonly found on beaches and estuaries, often mixed with flocks of other terns. Harsh grating calls similar to other terns.
