识别特征

小型昼行猛禽,以灰白色为主,肩部有黑色斑块,翅尖和贯眼纹黑色。翅长似隼,停栖时翅尖超过尾端;飞行时尾短而方,不像鸢属那样分叉。朝前的大眼睛红色,眼上有骨质眉棱遮光。停在路边电线上时常上下抖尾保持平衡。雌雄相似。

栖息环境

开阔的草原、农田、半荒漠和疏林,常在田野上空像红隼一样悬停,捕食鼠类和大型昆虫;在树上筑巢。

分布

分布于东洋界和非洲,另见于新几内亚、伊比利亚半岛、尼罗河流域和北非沿海;中国华南、华东近年明显扩张,新加坡的开阔草地和填海区常见;日本仅为迷鸟。

季节与习性

热带和华南全年可见,留鸟,随鼠类数量波动而增减。多在清晨和傍晚悬停觅食,白天停在电线和枯枝上。

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。

悬停时它比红隼更稳,侧光下白翅和黑肩的对比很干净,1/1600 秒即可;红眼要靠长焦大光圈拍停栖的肖像。傍晚它常停在同一根电线或枯树顶,用暖色天空做背景拍剪影加红眼的细节。

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

白与黑的几何;田野黄昏的剪影。

相似物种

澳洲黑肩鸢和北美白尾鸢是近缘种,分布不重叠;红隼(褐色,悬停姿态相似);鸥类飞行轮廓不同、不悬停。

Identification

A small diurnal raptor, mostly grey and white with black shoulder patches, wingtips and eye stripe. The long falcon-like wings extend past the tail when perched; in flight the tail is short and square, not forked like the Milvus kites. The large forward-facing eyes are red, shaded by a bony brow. On a roadside wire it jerks its tail up and down as if balancing. The sexes are alike.

Habitat

Open grassland, farmland, semi-desert and light woodland, hovering over fields like a kestrel for rodents and large insects; nests in trees.

Distribution

The Oriental region and Africa, with outposts in New Guinea, the Iberian Peninsula, the Nile valley and coastal North Africa; spreading noticeably in southern and eastern China and common over Singapore's open grass and reclaimed land; only a vagrant to Japan.

Season and behaviour

Resident and seen all year in the tropics and southern China, its numbers following the rodents. Hovers mainly at dawn and dusk and sits on wires and dead branches by day.

Photography tips

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

In the hover it is steadier than a kestrel, and in side light the white wings and black shoulders are clean at 1/1600 s; the red eye needs a long lens at a wide aperture on a perched bird. In the evening it returns to the same wire or dead treetop: a silhouette against the warm sky with the detail of the red eye.

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

Geometry of white and black; field silhouettes at dusk.

Similar species

The Australian black-shouldered kite and American white-tailed kite are close relatives whose ranges do not overlap; common kestrel (brown, similar hover); gulls have a different outline and do not hover.

Related badge

None yet. No validated photo recognition exists for this species, so no badge is tied to it: a name in the encyclopedia is not evidence in a photograph.

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.
