识别特征

中型海鸟,体长 30 到 32 厘米,翼展 52 到 58 厘米,体重 300 到 460 克。繁殖羽通体黑色,只有翅上一大块白斑;腿脚和口腔内鲜艳的珊瑚红色,嘴黑。秋季换羽后上体变成灰白相间的横斑,头淡灰,下体白,腿脚淡红,翅上白斑保留。雌雄在野外无法区分。

栖息环境

海岸和潮间带水域以及近海,比其他海雀更靠岸;在岩缝、巨石堆和码头的缝隙里营巢,多数地区为留鸟,高北极的种群冬季南迁。

分布

北欧、北大西洋和北极部分地区:加拿大、格陵兰、冰岛、不列颠群岛、斯堪的纳维亚和俄罗斯的海岸;太平洋一侧的是近缘的海鸽。日本仅有极个别记录,中国、新加坡无。

季节与习性

在东亚基本见不到;北大西洋的繁殖地 5 到 8 月在港口的防波堤上就能看到它们,红脚最醒目。

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。

繁殖期它停在防波堤和礁石上,红脚和张嘴时的红口腔是重点,顺光下 1/1000 秒;黑羽毛容易死黑,稍减曝光。它潜水前的一瞬和拍翅露出白斑的动作用连拍。

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

黑白红的海岸小品;港口礁石上的肖像。

相似物种

Identification

A medium-sized seabird, 30–32 cm long with a wingspan of 52–58 cm and weighing 300–460 g. In breeding plumage totally black except for a large white patch on the upper wing; legs, feet and the inside of the mouth bright coral red, bill black. After the autumn moult the upperparts are barred pale grey and white, the head pale grey, the underparts white and the feet pale red, the white wing patch retained. Sexes cannot be told apart in the field.

Habitat

Coastal and intertidal waters and inshore seas, staying closer to shore than other auks; nests in rock crevices, boulder scree and gaps in harbour walls; resident over most of its range, high-Arctic birds moving south in winter.

Distribution

Northern Europe, the North Atlantic and parts of the Arctic: the coasts of Canada, Greenland, Iceland, the British Isles, Scandinavia and Russia; the Pacific has the closely related pigeon guillemot. Only a very few records from Japan; absent from China and Singapore.

Season and behaviour

Hardly ever seen in East Asia; at North Atlantic colonies from May to August it sits on harbour breakwaters, the red feet the first thing you notice.

Photography tips

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

In the breeding season it perches on breakwaters and rocks: the red feet and the red gape when it calls are the point, front-lit at 1/1000 s; black plumage blocks up, so a little under. The moment before a dive and the wing flap that shows the white patch want bursts.

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

Black, white and red coastal studies; portraits on harbour rocks.

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.
