识别特征

身体丰满、翅短、嘴大的海鸟,是海雀科角嘴海雀属唯一现存的种,与海鹦近缘,有人建议称它「犀牛海鹦」。名字来自繁殖期成鸟嘴基上角一样的突起,只在繁殖季出现;眼后和嘴角各有一道白色饰羽,上体深灰,下体淡灰到白,嘴橙黄。主食小鱼,也吃无脊椎动物。一夫一妻,配偶关系可维持多年。

栖息环境

北太平洋寒冷海域的沿岸,在有植被覆盖的海岛上挖洞营巢,夜间归巢喂雏;非繁殖期在近海和外海活动。

分布

繁殖于北太平洋两岸:亚洲一侧的库页岛、千岛群岛、北海道和本州北部、朝鲜半岛,北美一侧从阿留申群岛、阿拉斯加到加利福尼亚海峡群岛;越冬南到日本南部和朝鲜半岛。北海道天卖岛有世界最大的繁殖群之一。中国、新加坡无。

季节与习性

日本北部 4 到 8 月繁殖,天卖岛 5 到 7 月黄昏成千上万只衔鱼归巢;冬季在日本近海可见。种群数量庞大,无危。

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。

天卖岛的黄昏归巢是经典场面:几十万只在暮色里飞回,用高感光度、1/1600 秒和连续对焦拍衔着一排鱼的个体,广角拍漫天的群体。白天只能从船上拍水面上的个体。繁殖洞穴区禁止踩踏,留在观察步道上。

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

暮色中成群归巢的剪影;灰色海面的小鸟。

相似物种

角海鹦、簇羽海鹦(嘴更大更红,脸白,繁殖期有饰羽);扁嘴海雀(更小,嘴小)。

Identification

A plump, short-winged, big-billed seabird, the only living species of its genus and a close relative of the puffins, for which the name rhinoceros puffin has been proposed. The name comes from the horn-like extension at the base of the bill in breeding adults, present only in the breeding season; white plumes run back from the eye and the gape, the upperparts are dark grey, the underparts pale grey to white, the bill orange-yellow. It eats mainly small fish, also invertebrates. Monogamous, with pair bonds lasting years.

Habitat

Cold North Pacific coasts, nesting in burrows on vegetated islands and returning at night to feed the chicks; offshore and inshore waters outside the breeding season.

Distribution

Breeds on both sides of the North Pacific: Sakhalin, the Kurils, Hokkaido and northern Honshu and Korea on the Asian side, and from the Aleutians and Alaska to California's Channel Islands on the American side; winters south to southern Japan and Korea. Teuri Island off Hokkaido holds one of the world's largest colonies. Absent from China and Singapore.

Season and behaviour

Breeds in northern Japan from April to August; at Teuri from May to July thousands return at dusk with fish; seen off Japan in winter. A very numerous species of least concern.

Photography tips

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

The dusk return to Teuri is the classic: hundreds of thousands flying in through the twilight, with high ISO, 1/1600 s and continuous focus for a bird carrying a row of fish, and a wide lens for the sky full of them. By day only birds on the water from a boat. The burrow slopes are closed to walking, so stay on the viewing paths.

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

Silhouettes of flocks returning at dusk; a small bird on a grey sea.

Similar species

Horned and tufted puffins (bigger redder bills, white faces, plumes when breeding); ancient murrelet (smaller, small bill).
