识别特征

体型最大的巨嘴鸟,平均体长 56 厘米。身体有光泽的黑色,喉和胸白色(有时带柠檬黄和一道红带),尾上覆羽白,尾下覆羽红。最显眼的是巨大的黄橙色嘴,基部黑色,末端有一大块黑斑。眼褐色,周围一圈细蓝环,眼周裸皮硫黄到橙色。不会被认错。

栖息环境

与多数栖息在雨林深处的巨嘴鸟不同,它偏好开阔的半开阔生境:稀树草原、林地、河岸林和种植园,在树洞里营巢,吃果实、昆虫和其他鸟的卵雏。

分布

南美洲特有,从圭亚那向南到阿根廷北部和乌拉圭,近年分布向南扩张。东亚只在动物园和鸟园可见,新加坡飞禽公园有饲养;《观鸟笔记》将它列为异域鸟。

季节与习性

鸟园全年可见;野外为留鸟。

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。

巨嘴是焦点,侧面才能看出它的长度和黑斑,顺光下橙色最饱和。黑色身体与橙嘴反差极大,对准嘴测光再加三分之一档。鸟园的个体常停在固定的横枝上,中焦就够;别喂食引它靠近。注明圈养。

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

橙与黑的大色块;巨嘴的侧面轮廓。

相似物种

其他巨嘴鸟(嘴色不同、体型更小);东南亚的犀鸟嘴上有盔突,不是近缘。

Identification

The largest toucan, averaging 56 cm long. Glossy black body, white throat and chest (sometimes with a citrine tint and a red band), white uppertail coverts and red undertail coverts. Its most conspicuous feature is the huge yellow-orange bill with a black base and a large black spot at the tip. Brown eye in a narrow blue ring with sulphur-yellow to orange bare skin around it. Unmistakable.

Habitat

Unlike most toucans of the deep rainforest, it prefers open and semi-open country: savanna, woodland, gallery forest and plantations, nesting in tree holes and eating fruit, insects and the eggs and chicks of other birds.

Distribution

Endemic to South America from the Guianas south to northern Argentina and Uruguay, its range expanding southward in recent years. In East Asia seen only in zoos and bird parks, including Singapore's; Birdwatching Notebook lists it as an exotic.

Season and behaviour

Seen all year in bird parks; resident in the wild.

Photography tips

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

The bill is the focus and only a profile shows its length and black spot, the orange most saturated in front light. Black body against orange bill is extreme contrast: meter on the bill and add a third of a stop. Park birds use fixed perches, so a medium lens is enough; do not feed it closer. Label it captive.

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

Big blocks of orange and black; the profile of a giant bill.

Similar species

Other toucans (different bill colours, smaller); South-East Asian hornbills have a casque and are unrelated.

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.
