野外识别 │ 雄鸟上体灰褐色，部分覆羽沾蓝色，初级飞羽内侧具白色横斑。颏至上胸银灰色，下体余部黄白色，具宽的黑褐色横斑。尾羽褐色，羽端微具白色，羽轴两侧有成对排列的白斑。雌鸟有棕色型和灰色型。鸣声为“ sit hoop-hoop-hoop ”，第二个音节较长和响亮、传播很远，重复 5~10 次。

居留及分布 │ 分布于西伯利亚至堪察加半岛、日本、朝鲜、亚洲中部、印度东北部、缅甸。越冬于中南半岛至澳大利亚。在中国分布有两个亚种，主要为夏候鸟。在南岭也为夏候鸟，在大顶山、乳阳有分布。

生境及习性 │ 栖息于山地针叶林、针阔叶混交林和阔叶林等茂密的森林中，偶尔也出现于山麓平原人工林和林缘地带。常单独活动，多站在高大而茂密的树上不断地鸣叫。主要以昆虫为食。繁殖期 5—7 月。无固定配偶，也不自己营巢和孵卵，将卵产在雀形目鸟类的巢中。

Field identification │ Slightly smaller than Common Cuckoo subspecies bakeri but very similar in appearance and on current knowledge not separable in the field unless giving its territorial call—a four-note phrase consisting of a short introductory note followed by three mellow longer notes sit hoop hoop-hoop .

Distribution & status │ Breeds from the Himalayan foothills of Nepal and N India through Myanmar to eastern China, and winters in Indonesia and the Philippines. It is a summer visitor to parts of southern, central and eastern China, including Nanling where it has been recorded at Dadingshan and Ruyang.

Habitat & habits │ Himalayan Cuckoos occur in a variety of wooded habitats including hill forests, where they feed on insects including caterpillars and flying ants. They are nest-parasitic, but host species in Guangdong are unknown.
