识别特征

中型鸮,身形纤细、翅长,有可竖起的长耳簇羽,位置比多数鸮更靠近头顶中央。底色赭黄褐色,带灰或褐色的罩染,覆盖着深色纵纹,翅和背最明显;肩羽有白斑。面盘橙黄色,眼橙色。飞行时翅下腕部有深色斑和淡黄到近橙的翼板。

栖息环境

半开阔的环境,尤其是林缘:在茂密的林带里夜宿和繁殖,到开阔地上空捕食鼠类;冬季在公园、墓园和防风林的常绿树上集群夜宿,一棵树上可有十几只。

分布

广布欧洲、古北界和北美。中国北方繁殖,华北到长江流域越冬,北京等北方城市的公园冬季有稳定的集群栖息点;日本北部繁殖、全国越冬;新加坡无。

季节与习性

中国东部、日本 11 月到次年 3 月最容易观察,白天在柏树或松树里一动不动;3 到 6 月繁殖,利用喜鹊等的旧巢。

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。

冬季集群是最好的机会,也是最需要克制的时候:别靠近到让它们睁大眼睛竖起耳羽,那已经是受惊的信号;用 600mm 从远处拍半闭眼的安睡状态。枝叶间的缝隙用大光圈虚化;绝不用闪光灯,也别在栖息点附近喧哗或久留。

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

针叶枝间的肖像;低调的褐与橙。

相似物种

短耳鸮(耳簇羽极短,眼黄,在开阔草地白天活动);雕鸮(大得多);纵纹腹小鸮(小,无耳羽)。

Identification

A medium-sized owl, slim and long-winged, with erectile ear tufts set closer to the centre of the head than in most owls. Ochraceous-tawny with a grey or brown wash, overlaid with dark vertical streaks most apparent on wings and back; the scapulars are marked whitish. Orange-buff facial disc, orange eyes. In flight the underwing shows dark carpal patches and buff to near-orange panels.

Habitat

Semi-open country, particularly woodland edge: roosts and nests in dense stands of trees and hunts rodents over open ground; in winter it roosts communally in evergreens in parks, cemeteries and shelterbelts, sometimes a dozen in one tree.

Distribution

Widespread in Europe, the Palearctic and North America. Breeds in northern China and winters from the north to the Yangtze basin, with regular winter roosts in the parks of Beijing and other northern cities; breeds in northern Japan and winters throughout; absent from Singapore.

Season and behaviour

Easiest to watch in eastern China and Japan from November to March, motionless by day in a cypress or pine; breeds from March to June in old nests of magpies and other birds.

Photography tips

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

The winter roost is the best chance and the time for most restraint: never go close enough for them to open their eyes wide and raise their tufts, which is already alarm; use 600 mm from a distance for the half-closed sleeping look. A wide aperture softens the gaps in the foliage; never use flash, and do not linger or talk near a roost.

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

Portraits among conifer branches; quiet brown and orange.

Similar species

Short-eared owl (very short tufts, yellow eyes, hunts open grassland by day); eagle owl (much larger); little owl (small, no tufts).

Related badge

The album badge "an owl" unlocks when the vision model explicitly names a an owl in your photo and you rate the analysis. The badge stops at "an owl": it does not tell species apart, and this page existing unlocks nothing.

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.
