识别特征

体长 24.5 到 28 厘米,翼展 52 到 59 厘米,雄鸟 51 到 101 克,雌鸟 67 到 95 克。上体灰褐带深色纵纹,后颈有淡黄色领环,有白色的髭纹;收起的翅灰色带淡黄斑,下体灰褐带褐色横纹和淡黄斑。嘴黑,虹膜深褐,腿脚褐色。羽毛柔软,飞行无声而轻盈,翅长而尖。雄鸟飞行时三枚初级飞羽上有白斑、外侧两枚尾羽端白,雌鸟没有白色。

栖息环境

开阔的林地、林缘、荒地和新伐区,白天贴在地面或顺着树枝休息;黄昏在空中捕食飞蛾和甲虫。中亚夜鹰仅根据 1929 年新疆的一件标本描述,现在一般视为它的同种异名。

分布

繁殖于欧洲大部分地区和古北界到蒙古和中国西北;六个亚种越往东越小越淡;全部迁徙,越冬于非洲。中国新疆、内蒙古西部为夏候鸟;日本、新加坡无。属名来自夜鹰吸羊奶的古老传说。

季节与习性

新疆 5 到 8 月,黄昏后雄鸟发出持续数分钟的「嘟噜噜」颤音;白天极难发现。

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。

白天找到它靠运气和眼睛的反光,找到后远远用长焦,别靠近也别打灯。黄昏飞行用高感光度、1/800 秒追焦,对着亮天空拍剪影,雄鸟翅上的白斑是识别点。它在碎石地上的伪装拍成特写就是题材本身。

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

伪装与地面纹理;黄昏天空的剪影。

相似物种

Identification

24.5–28 cm long, wingspan 52–59 cm, males 51–101 g, females 67–95 g. Greyish-brown upperparts with dark streaking, a pale buff hindneck collar and a white moustachial line; the closed wing grey with buff spotting, the underparts greyish-brown with brown barring and buff spots. Blackish bill, dark brown iris, brown legs and feet. Soft plumage makes the flight on long pointed wings silent and very buoyant. In flight the male shows a white patch across three primaries and white tips to the two outer tail feathers; females show no white.

Habitat

Open woodland, forest edge, heath and clearings, resting by day on the ground or along a branch; hawks moths and beetles at dusk. The Vaurie's nightjar, described from a single 1929 Xinjiang specimen, is now generally treated as a synonym of this species.

Distribution

Breeds across most of Europe and the Palearctic to Mongolia and north-western China; six subspecies grow smaller and paler eastward; all migrate to winter in Africa. A summer visitor to Xinjiang and western Inner Mongolia; absent from Japan and Singapore. The generic name recalls the old myth that nightjars suckled goats.

Season and behaviour

In Xinjiang from May to August, the male churring for minutes on end after dusk; very hard to find by day.

Photography tips

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

Finding one by day is luck and the glint of an eye; then a long lens from far off, no approach and no light. For dusk flight use high ISO and 1/800 s tracking against the bright sky for a silhouette, the male's white wing spots the mark. Its camouflage on gravel, shot as a close-up, is the subject in itself.

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

Camouflage and ground texture; silhouettes against the dusk sky.
