识别特征

大型鹤,站高约 140 厘米,体重 4.9 到 8.6 公斤,翼展 210 到 260 厘米。成鸟通体雪白,只有初级飞羽、小翼羽和初级覆羽黑色,飞行时才显露;前额、脸和头侧裸露呈砖红色,嘴深色,腿粉红,虹膜淡黄。幼鸟脸部有羽毛,体羽暗褐。没有其他鹤那样延长的三级飞羽。叫声不像多数鹤的号角声,而是像雁一样的高亢哨音。

栖息环境

繁殖于北极苔原的湿地;越冬于浅水湖泊和沼泽,在浅水里挖食水生植物的块茎,是最依赖湿地的鹤。

分布

两个繁殖种群:东部种群繁殖于西伯利亚东北部,越冬于中国,几乎全部在鄱阳湖;西部种群繁殖于西西伯利亚,越冬于伊朗(以前还有印度的巴拉特普尔),已仅存个位数。全球约四千只,列为极危。日本偶有迷鸟,新加坡无。

季节与习性

鄱阳湖 11 月到次年 3 月,是全球几乎全部白鹤的越冬地,常与白枕鹤、灰鹤和各种雁鸭混群;3 月底北迁。

拍摄建议

以下为 FilmAnalysis 编辑的拍摄经验,不是资料来源中的内容。

鄱阳湖的草洲和浅滩是唯一的主场,用车或隐蔽帐篷,600mm 起步,让画面留足空间:白色大鸟在冬日的黄褐色草洲上本身就是画。清晨薄雾里的群体和起飞时露出黑色翼尖的瞬间最好,1/1600 秒。白羽毛减半档。它们是极危物种,与群体保持数百米距离。

拍鸟守则:与鸟保持它不改变行为的距离;不靠近、不公开巢和繁殖地点;不用食物、录音回放或闪光灯引诱;不修剪巢周围的枝叶;在保护区遵守观察区和步道的规定。

适合的摄影风格

湖滩薄雾中的白色大鸟;黑色翼尖的瞬间。

相似物种

白枕鹤(头顶红、颈侧灰白条纹、体灰);丹顶鹤(颈黑、三级飞羽黑、头顶红);东方白鹳(嘴粗直、腿红,次级飞羽也黑)。

Identification

A fairly large crane standing about 140 cm, weighing 4.9–8.6 kg with a wingspan of 210–260 cm. Adults are pure white except for black primaries, alula and primary coverts, visible in flight; the forecrown, face and head sides are bare brick-red, the bill dark, the legs pinkish, the iris yellowish. Juveniles have feathered faces and dingy brown plumage. There are no elongated tertials as in other cranes. The call is not a trumpet but a goose-like high whistle.

Habitat

Breeds on Arctic tundra wetlands; winters on shallow lakes and marshes, digging the tubers of water plants in the shallows, the most wetland-dependent of all cranes.

Distribution

Two breeding populations: the eastern breeds in north-east Siberia and winters in China, almost entirely at Poyang Lake; the western breeds in western Siberia and winters in Iran (formerly also at Bharatpur, India) and is down to a handful of birds. About four thousand remain worldwide; critically endangered. An occasional vagrant to Japan; absent from Singapore.

Season and behaviour

At Poyang Lake from November to March, where nearly all the world's Siberian cranes winter, often with white-naped and common cranes and many geese and ducks; departs north in late March.

Photography tips

These are the FilmAnalysis editors' notes, not content from the sources.

The grasslands and shallows of Poyang are the only stage: a car or hide, 600 mm upwards, and room in the frame, since a great white bird on tawny winter grass is the picture by itself. Groups in early mist and the take-off that reveals the black wingtips are the best moments, at 1/1600 s; half a stop under for white plumage. A critically endangered species: keep hundreds of metres from the flock.

Field ethics: keep a distance at which the bird does not change its behaviour; never approach or publish nest sites; no baiting, playback or flash; never clear vegetation around a nest; follow reserve rules and stay on paths.

Photographic styles

Great white birds in lake mist; the instant of black wingtips.

Similar species

White-naped crane (red crown, grey-and-white striped neck, grey body); red-crowned crane (black neck and tertials, red crown); Oriental stork (thick straight bill, red legs, black secondaries too).

Related badge

The album badge "a crane" unlocks when the vision model explicitly names a a crane in your photo and you rate the analysis. The badge stops at "a crane": it does not tell species apart, and this page existing unlocks nothing.

Why it is listed: this species comes from the Birdwatching Notebook species list (names checked against IOC 15.2). Names follow the IOC World Bird List 15.2; the facts follow the sources below; photo recognition is not offered.
