识别特征

小型角鸮,羽色多变,眼黄色,耳簇羽并不总是竖起。有灰色和棕红色两种色型,也有中间型。与领角鸮的区别是肩部有一道白色条纹、下体斑纹清楚、没有淡色的颈环。雌雄相似。受惊时会半闭着眼僵住不动。叫声是重复的、像水滴一样的「tuk tok torok」。

栖息环境

干燥的落叶林、疏林、公园和寺庙的古树;在树洞里营巢,2 到 4 月繁殖。白天贴着树干休息,靠羽色隐蔽。

分布

分布极广,横跨东亚和南亚,从俄罗斯远东到泰国;中国东部和日本(日本称「木叶木菟」)为夏候鸟,越冬于东南亚,新加坡每年过境季在公园里都能发现停歇的个体,是观鸟者的热门目标。

季节与习性

中国东部、日本 4 到 10 月,夏夜在林中反复鸣叫;新加坡 10 到 12 月和 3 到 4 月过境。白天在公园的树上休息时常被鸟友围观。

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。

它白天一动不动,围观的人才是问题:站远、用长焦、别超过十分钟,更不要用闪光灯或回放叫声。黄色的眼睛半闭时拍不出神采,等它自然睁眼的一瞬。树干纹理和羽色几乎一致,用大光圈把背景分离出来。

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

树干纹理里的伪装肖像;低饱和的灰棕。

相似物种

领角鸮(更大,眼橙或褐色,有淡色颈环);巽他领角鸮(眼深色,热带);日本角鸮(琉球,叫声不同)。

Identification

A small scops owl of variable plumage with yellow eyes and ear tufts that are not always raised. Grey and rufous morphs with intermediates. Told from the collared scops owl by a whitish scapular stripe, well-marked underparts and no pale collar. Sexes alike. When disturbed it freezes with half-closed eyes. The call is a repeated liquid tuk tok torok.

Habitat

Dry deciduous forest, open woodland, parks and old temple trees; nests in tree holes from February to April. Roosts by day pressed against a trunk, hidden by its plumage.

Distribution

Extremely widespread across eastern and southern Asia from the Russian Far East to Thailand; a summer visitor to eastern China and Japan, wintering in South-East Asia, and every passage season birds rest in Singapore's parks, a favourite of birders.

Season and behaviour

In eastern China and Japan from April to October, calling through summer nights in the woods; passage in Singapore in October–December and March–April. Daytime roosts in parks often draw a crowd.

Photography tips

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

It does not move by day; the crowd is the problem. Stand back, use a long lens, stay no more than ten minutes, and never use flash or playback. Half-closed yellow eyes have no life, so wait for the moment it opens them naturally. Bark and plumage match almost exactly, so a wide aperture separates the background.

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 portraits in bark texture; muted grey-brown.

Similar species

Collared scops owl (larger, orange or brown eyes, pale collar); Sunda scops owl (dark eyes, tropics); Ryukyu scops owl (Ryukyus, different call).

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.
