识别特征

中到大型鹮,体长 55 到 78.5 厘米,脸部裸露呈红色,枕部有一簇浓密下垂的冠羽。羽色随季节变化:冬季以白色为主,翅和尾带鲑粉色;夏季上体和胸淡灰,背上有一片深灰的「披肩」,下体白带粉。飞行时翅和尾的上面白色,飞羽和尾羽的下面浓浓的粉红。嘴长而强烈下弯,黑色带红尖;腿和脚红色。

栖息环境

温带山区的水田、河滩和湿地,在水田和浅溪里觅食泥鳅、蛙和水生昆虫,在高大的松树和栎树上营巢和夜宿;对农田的无农药环境依赖很深。

分布

曾广布中国东部、朝鲜半岛和日本,二十世纪后期野生种群仅剩陕西洋县的七只;经保护,2014 年野外约一千余只,2021 年总数已恢复到七千余只,并重引入到韩国和日本佐渡岛。日文名「朱鹭」,学名就是「日本」。新加坡无。

季节与习性

陕西汉中盆地全年可见,3 到 6 月繁殖,夏羽偏灰;冬季白中带粉,在收割后的水田里成群觅食。佐渡岛的放归种群全年可见。

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。

飞行时翅下的粉红是它最动人的颜色,要在逆光或侧逆光下、以天空或暗山为背景,1/1600 秒。冬季白中泛粉的羽毛在柔光里最准,直射光下容易过曝。洋县的鸟与农民相处多年,但仍要用长焦远拍,巢树和夜宿地一律不靠近,这是国家一级保护动物。

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

水田上空的粉红翅膀;温润的中国山村色调。

相似物种

白琵鹭(嘴扁平、不下弯);白鹭类(嘴直、腿黑、无粉色)。

Identification

A medium-to-large ibis, 55–78.5 cm long, with a bare red face and a dense drooping crest of plumes on the nape. The plumage changes with season: in winter largely white with salmon-pink tones on the wings and tail; in summer pale grey above and on the breast with a darker grey shawl across the back, white tinged pink below. In flight the upper wings and tail are white and the undersides of the flight feathers strongly flushed pink. The long, strongly downcurved bill is black with a red tip; legs and feet red.

Habitat

Paddies, river beds and wetlands in temperate hills, feeding on loach, frogs and water insects in paddies and shallow streams, nesting and roosting in tall pines and oaks; dependent on pesticide-free farmland.

Distribution

Once widespread across eastern China, Korea and Japan; by the late twentieth century the wild population was down to seven birds at Yangxian, Shaanxi. Protection brought about a thousand wild birds by 2014 and more than seven thousand in all by 2021, with reintroductions in South Korea and on Sado Island, Japan. Called toki in Japanese, and its scientific name is simply Japan. Absent from Singapore.

Season and behaviour

Seen all year in the Hanzhong basin of Shaanxi, breeding from March to June in greyish summer plumage; in winter, white tinged pink, it feeds in flocks on harvested paddies. The released Sado population is present all year.

Photography tips

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

The pink under the wings in flight is its most moving colour: backlight or side backlight against sky or a dark hill, at 1/1600 s. The pink-white winter plumage is truest in soft light and clips easily in direct sun. The Yangxian birds have lived beside farmers for years, but still use a long lens and never approach nest trees or roosts: a first-class protected species.

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

Pink wings over paddies; the gentle tones of a Chinese mountain village.

Similar species

Eurasian spoonbill (flat bill, not downcurved); egrets (straight bill, black legs, no pink).
