识别特征

雄鸟体长 16 到 19 厘米,其中外侧尾羽长 12 厘米,体重 5 到 6 克;雌鸟 9.7 到 11.7 厘米,4.5 到 4.7 克。嘴短而黑。指名亚种雄鸟头顶闪亮的翠绿,上体金属古铜绿,下体较暗的绿带橄榄色调,喉蓝或紫;内侧尾羽极短、外侧极长,尾上面闪蓝、绿、紫的虹彩,下面蓝黑。雌鸟尾短而略分叉,下体肉桂色。

栖息环境

安第斯山地的半开阔高大林地和林缘,吸食花蜜,留鸟。

分布

从委内瑞拉经哥伦比亚、厄瓜多尔、秘鲁到玻利维亚中西部的安第斯山区。东亚无分布,《观鸟笔记》将它列为异域鸟。

季节与习性

留鸟,分布区内全年可见。

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。

长尾在悬停时拖在身后像两条丝带,要留出下方的空间,竖幅;1/3200 秒凝固翅膀,长尾本身会轻微拖影,那正是动感。虹彩只在顺光和正对时出现。安第斯的观鸟小屋喂食器是现实的拍摄点。

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

拖着长尾悬停的蜂鸟;绿与紫的虹彩。

Identification

Males are 16–19 cm long including the 12 cm outer tail feathers and weigh 5–6 g; females 9.7–11.7 cm and 4.5–4.7 g. A short black bill. Nominate males have a shining emerald crown, metallic bronzy-green upperparts, duller olive-tinged green underparts and a blue or violet throat; the inner tail feathers are very short and the outer very long, the tail iridescent blue, green and violet above and bluish black below. Females have a short, somewhat forked tail and cinnamon underparts.

Habitat

Semi-open tall woodland and forest edge in the Andes, feeding on nectar; resident.

Distribution

The Andes from Venezuela through Colombia, Ecuador and Peru to west-central Bolivia. Absent from East Asia; Birdwatching Notebook lists it as an exotic.

Season and behaviour

Resident, seen all year within its range.

Photography tips

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

The long tail trails behind the hover like two ribbons, so leave space below and use a portrait frame; 1/3200 s freezes the wings while the tail itself blurs slightly, which is the movement. The iridescence appears only front-lit and head-on. Andean lodge feeders are the realistic place.

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

A hovering hummingbird trailing a long tail; green and violet iridescence.

Similar species

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.

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.
