识别特征

粗壮的鹀类,有一个厚厚的黄色食籽嘴。夏季雄鸟头和喉黑色,白色眉纹,后颈栗色,下体白,背黑灰色带浓重纵纹;其他羽色(雌鸟、冬羽)头部为较朴素的橙褐色,背更褐,后颈和翅上有栗色斑块。体长 15 到 16 厘米,体重 22 到 33 克,翼展 22 到 29 厘米。后爪很长,是「铁爪」的由来。

栖息环境

开阔地区:北极苔原繁殖;冬季栖息于草地、沼泽、平原农田和丘陵的稀疏林地,常在收割后的田里成群在地面奔走觅食种子,与云雀、雪鹀混群。

分布

环极地繁殖于北极欧洲、古北界、加拿大和美国最北部;越冬于俄罗斯草原、美国南部等地。中国东北、内蒙古、河北、江苏、湖北、四川、甘肃等地冬季有分布,华北平原的农田常见;日本为少见冬候鸟;新加坡无。

季节与习性

中国北方 10 月到次年 4 月在农田成群活动,雪后在裸露的地面上最容易看见;5 到 7 月在北极繁殖。

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。

冬羽朴素,栗色的后颈和翅斑是辨识的线索,趴在田埂上用长焦等它们走近。雪地背景加一档曝光。春季 3 到 4 月北迁前部分雄鸟换出黑脸,是一年里最好的机会。群体起落频繁,1/1600 秒。

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

雪后农田上的褐色小鸟;朴素的冬日纪实。

相似物种

雪鹀(翅有大片白色);田鹀、黄眉鹀等鹀类(无栗色后颈和长后爪);云雀(有短冠羽、嘴细)。

Identification

A robust bunting with a thick yellow seed-eater's bill. The summer male has a black head and throat, white eye-stripe, chestnut nape, white underparts and a heavily streaked black-grey back; other plumages have a plainer orange-brown head, browner back and chestnut nape and wing panels. 15–16 cm long, 22–33 g, wingspan 22–29 cm. The long hind claw gives the name longspur.

Habitat

Open country: Arctic tundra when breeding; in winter grassland, marsh, plain farmland and sparse hill woodland, running over the ground of stubble fields in flocks for seeds, mixed with larks and snow buntings.

Distribution

Circumpolar breeder across Arctic Europe, the Palearctic, Canada and the northernmost United States; winters on the Russian steppes, in the southern United States and elsewhere. In China in winter in the north-east, Inner Mongolia, Hebei, Jiangsu, Hubei, Sichuan and Gansu, common on North China Plain farmland; a scarce winter visitor to Japan; absent from Singapore.

Season and behaviour

In northern China from October to April in flocks on farmland, easiest on bare ground after snow; breeds in the Arctic from May to July.

Photography tips

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

Winter plumage is plain, and the chestnut nape and wing panels are the clue: lie on a field bank with a long lens and let them walk up. Add a stop for snow. Before northward migration in March–April some males show the black face, the best chance of the year. Flocks rise and settle constantly, so 1/1600 s.

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

Brown birds on snow-dusted fields; plain winter documentary.

Similar species

Snow bunting (large white wing areas); rustic, yellow-browed and other buntings (no chestnut nape or long hind claw); skylark (short crest, thin bill).
