识别特征

最大的紫耳蜂鸟,体长 13 到 14 厘米,雄鸟 5.8 到 8.5 克,雌鸟 6 到 7.5 克。指名亚种雄鸟上体金属蓝绿,颏蓝紫,腹蓝,其余下体绿;耳部覆盖着长而可竖起的蓝紫色羽毛,尾金属绿、近端有钢蓝色带。雌鸟相似但更小,眼后常有白点。叫声响亮,领域性极强。

栖息环境

多种半开阔生境,包括基多等大城市的花园和公园,常是分布区内最常见的蜂鸟;比绿紫耳蜂鸟更偏好潮湿环境。

分布

南美洲北部和西部的高原:安第斯山脉从阿根廷北上、委内瑞拉海岸山脉和特普伊桌山。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,终日在固定的花丛和喂食器前守卫领域。

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。

它守着一丛花反复回到同一根枝上,预对焦在那根枝上,顺光,1/2500 秒;竖起的紫色耳羽在它驱赶对手时最明显。城市公园和旅馆花园里就能拍,不必进林子。

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

城市花园里的蓝绿蜂鸟;竖起的紫耳。

相似物种

绿紫耳蜂鸟(更小,腹绿不蓝,颏不紫);褐紫耳蜂鸟(褐色)。

Identification

The largest violetear, 13–14 cm long, males 5.8–8.5 g and females 6–7.5 g. The nominate male is metallic bluish green above with a bluish-violet chin, blue belly and green on the rest of the underparts; long erectile bluish-violet plumes cover the ears, and the tail is metallic green with a steely blue band near the end. Females are similar but smaller, often with a white spot behind the eye. Highly vocal and territorial.

Habitat

A wide range of semi-open habitats including gardens and parks in major cities such as Quito, often the commonest hummingbird in its range; prefers moister places than the lesser violetear.

Distribution

The highlands of northern and western South America: the Andes from Argentina northward, the Venezuelan Coastal Range and the tepuis. Absent from East Asia; Birdwatching Notebook lists it as an exotic.

Season and behaviour

Resident, seen all year within its range, guarding a patch of flowers or a feeder all day.

Photography tips

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

It guards one clump of flowers and returns to the same perch: prefocus there, front-lit, 1/2500 s; the raised violet ear plumes show best when it drives off a rival. City parks and hotel gardens are enough, with no need to enter the forest.

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 blue-green hummingbird in a city garden; raised violet ears.

Similar species

Lesser violetear (smaller, green not blue belly, no violet chin); brown violetear (brown).

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.
