识别特征

中型海鸥。成鸟上体淡灰,头和下体白,翼尖纯黑像蘸过墨水、没有白斑;嘴黄色无红点,腿短而黑,眼深色。冬羽后颈有一块灰斑。幼鸟翅上有黑色的「M」形斑纹,颈后有黑色半环,尾端黑带。英文名来自它的叫声「kittee-wa-aaake」。

栖息环境

鸥类中最远洋性的一种,除 5 到 9 月的繁殖期外几乎都在海上;繁殖于最陡峭的海崖上,巢筑在极窄的岩架上。

分布

北极到亚北极的海岸鸟,北大西洋从加拿大到格陵兰、欧洲,北太平洋从阿拉斯加到西伯利亚沿岸;越冬区南到新泽西、中国、马尾藻海和西非外海。日本沿海冬季常见(尤其北部),中国东部沿海少量;新加坡无。全球数量下降,列为易危。

季节与习性

日本北部沿海 11 月到次年 3 月,北海道的渔港和海岸能见到群体;中国东部沿海冬季零星。在海面上轻盈地拍打飞行,常跟随渔船。

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。

墨黑的翼尖是识别和构图的重点,飞行时从船上或防波堤顺光拍,1/2000 秒。它比其他鸥飞得更轻快,追焦要早。冬日灰色海面和灰白的鸟是一体的低饱和调子,适合留白的极简构图。

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

灰海与白鸥的极简;墨色翼尖的细节。

相似物种

红嘴鸥(翼前缘白、冬羽耳后黑点、腿红);普通海鸥(翼尖黑中有白斑,腿黄绿);幼年的「M」纹与小鸥幼鸟相似但大得多。

Identification

A medium-sized gull. Adults are pale grey above with white head and underparts and wingtips of solid black as if dipped in ink, without white spots; the bill is yellow without a red spot, the legs short and black, the eye dark. In winter a grey smudge on the nape. Juveniles have a black M across the wings, a black half-collar and a black tail band. The English name comes from its call, kittee-wa-aaake.

Habitat

The most pelagic of the gulls, almost always at sea except in the May to September breeding season, when it nests on the sheerest sea cliffs on the narrowest ledges.

Distribution

A coastal bird of Arctic and subarctic regions, across the northern Atlantic from Canada to Greenland and Europe and in the Pacific from Alaska to the Siberian coast; the winter range extends south to New Jersey, China, the Sargasso Sea and off West Africa. Common in winter off Japan, especially the north, and in small numbers off eastern China; absent from Singapore. Declining worldwide; listed as vulnerable.

Season and behaviour

Off northern Japan from November to March, with flocks in Hokkaido's fishing ports and along the coast; scattered off eastern China in winter. A buoyant flier over the sea that often follows fishing boats.

Photography tips

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

The inky wingtips are the mark and the point of the picture: front-lit flight from a boat or breakwater at 1/2000 s. It flies more lightly than other gulls, so start tracking early. Grey winter sea and grey-white bird are one low-saturation tone, made for minimal compositions with empty space.

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

Grey sea and white gull; the detail of ink-black wingtips.

Similar species

Black-headed gull (white leading edge, dark ear spot in winter, red legs); common gull (white spots in the black wingtips, yellow-green legs); the juvenile M pattern resembles a young little gull but is much larger.

Related badge

The album badge "a gull" unlocks when the vision model explicitly names a a gull in your photo and you rate the analysis. The badge stops at "a gull": 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.
