识别特征

中型鸮,体长 35 到 40 厘米。头圆,没有耳簇羽,深褐色带淡色细点;羽色暖黄褐,杂以浅褐、深褐和白色;胸淡褐与白色相间,带深褐色纵纹,翅和尾较深,有白色横带。面盘较淡,黄色小钩嘴,眼深色。雌雄外形相同。夜行性,在分布区大部分地方都难得一见,研究很少。

栖息环境

山地的针叶林、阔叶林和混交林,在树洞和岩缝里营巢;夜间在林中捕食小型哺乳动物和鸟类,白天贴着树干休息。

分布

喜马拉雅山脉到东亚:从尼泊尔、不丹经中国西南、华中到华东、华北山区,以及台湾和朝鲜半岛。曾被视为灰林鸮的亚种。日本、新加坡无。数量在减少但分布广,列为无危。

季节与习性

留鸟,全年可见;2 到 4 月的夜里发出「呼、呼呼」的叫声,是定位它的主要线索;白天偶尔在公园和寺庙的大树上被发现。

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。

白天在大树的树干旁找到它休息时,隔着距离用长焦,1/250 秒配合稳定;深色的眼睛在柔光里才看得出轮廓。绝不用闪光灯和回放,也不长时间围观;一旦它睁大眼睛盯着你就退后。

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

树干旁的圆头剪影;暖褐色的低调。

相似物种

灰林鸮(欧洲和西亚的近缘种,曾合并);长尾林鸮(更大、尾更长、面盘灰,东北);褐林鸮(更大,面盘黑边,华南)。

Identification

A medium-sized owl, 35–40 cm long. Round head without ear tufts, dark brown with pale speckling; warm tawny plumage marked light brown, dark brown and white; the breast light brown and white with dark brown vertical streaks, wings and tail darker with white bars. A paler facial disc, a small hooked yellow bill and dark eyes. Sexes alike. Nocturnal and rarely seen over most of its range, with few studies.

Habitat

Mountain conifer, broadleaf and mixed forest, nesting in tree holes and rock crevices; hunts small mammals and birds in the forest at night and roosts by day against a trunk.

Distribution

The Himalayas to East Asia: from Nepal and Bhutan through south-west, central, eastern and northern China's hills to Taiwan and Korea. Formerly a subspecies of the tawny owl. Absent from Japan and Singapore. Declining but widespread; least concern.

Season and behaviour

Resident, seen all year; its hooting on February to April nights is the main clue; occasionally found by day in big trees in parks and temple grounds.

Photography tips

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

When you find it roosting against a big trunk by day, use a long lens from a distance at about 1/250 s with stabilisation; the dark eyes read only in soft light. Never use flash or playback and never crowd it; once it opens its eyes wide at you, step back.

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

Round-headed silhouettes beside a trunk; quiet warm brown.

Similar species

Tawny owl (the European and West Asian relative, once lumped); Ural owl (larger, longer tail, grey disc, north-east); brown wood owl (larger, dark-rimmed disc, southern China).

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.

The illustration is original FilmAnalysis artwork. The photograph is from Wikimedia Commons; its licence and author are under it.

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.
