识别特征

体长 28 厘米,平均体重约 120 克。上体沙米色,胸灰白,次级飞羽和初级飞羽尖端有闪亮的深蓝色;嘴长而下弯,额有一道黑纹(黑色的头顶)。尾黑色,中文名由此而来。腿长,在地面奔跑迅速,不喜飞。

栖息环境

温带荒漠:稀疏的盐生灌木和半灌木地带,偏好砾石地面;在灌木里筑巢,吃昆虫、种子和小型爬行动物,会藏食。

分布

中亚干旱区:蒙古西部和南部、中国新疆北部和东部、青海到内蒙古西部,以及哈萨克斯坦和俄罗斯邻近地区(模式产地新疆莎车)。受栖息地丧失和破碎化威胁。日本、新加坡无。

季节与习性

留鸟,全年可见,清晨在戈壁上奔跑觅食最活跃;4 到 6 月繁殖。

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。

它在戈壁上奔跑,用车慢慢跟,等它停在石头或灌木顶上张望,长焦顺光拍;蓝色的翅斑只在翅膀张开的瞬间和顺光下闪现,1/2000 秒。沙色的鸟在沙色的地上要靠影子和轮廓,早晚的低光最好。

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

戈壁砾石上的沙色鸟;一闪的蓝。

相似物种

白尾地鸦(尾白、头顶黑,仅新疆塔里木盆地);其他地鸦分布不重叠。

Identification

28 cm long, averaging about 120 g. Sandy-beige upperparts, off-white breast, iridescent dark blue on the secondaries and primary tips; a long decurved bill and a black stripe on the forehead (black crown). Black tail, hence the Chinese name. Long-legged, running fast over the ground and reluctant to fly.

Habitat

Temperate desert: sparse saltbush and semi-shrub country, preferring gravel surfaces; nests in a bush, eats insects, seeds and small reptiles and caches food.

Distribution

The arid heart of Central Asia: western and southern Mongolia, northern and eastern Xinjiang and Qinghai to western Inner Mongolia in China, and adjacent Kazakhstan and Russia (type locality Yarkand, Xinjiang). Threatened by habitat loss and fragmentation. Absent from Japan and Singapore.

Season and behaviour

Resident, seen all year, most active running over the gobi at dawn; breeds from April to June.

Photography tips

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

It runs across the gobi: follow slowly by car and wait for it to stop on a stone or bush top, then a front-lit long lens; the blue wing flashes only in the instant the wings open in front light, at 1/2000 s. A sand-coloured bird on sand needs shadow and outline, so the low light of morning and evening is best.

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 sand-coloured bird on gobi gravel; a flash of blue.

Similar species

Xinjiang ground jay (white tail, black cap, Tarim Basin only); other ground jays do not overlap.

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.
