野外识别 │ 通体黑色，具蓝色光泽，尾呈浅叉状，尾下覆羽和外侧尾羽具白色横斑，飞羽内侧有白色横斑和块状白斑。鸣声由 4~6 个均匀的pi音节组成，似口哨声，音阶渐次升高，恰如“I am a drongo cuckoo”。

居留及分布 │ 分布于亚洲南部、亚洲东南部、中国等地，国内分布于西南和南部。在南岭为夏候鸟，分布于秤架、大东山、乳阳等地。

生境及习性 │ 栖息于山地和平原茂密的森林中，也出现于林缘次生林、灌木林和耕地及村屯附近稀树荒坡地带，在树上活动和栖息，常停息在乔木中上层顶枝间鸣叫。以昆虫为食，偶尔也吃植物的果实和种子。繁殖期 3—5 月。自己不营巢和孵卵，常把卵产于卷尾、燕尾等鸟类的巢中。繁殖数据缺乏。

Field identification │ A slim, drongo-like cuckoo with a slightly forked tail and a slender, arched bill. Adults are glossy bluish-black overall except for the undertail coverts and outermost undertail feathers which are finely barred white. Juveniles are dull blackish with a variable amount of white spotting on the body, wing-coverts and tail-tips. The territorial call is a loud clear 4-6 notes whistle which rises in tone (rendered in English as“I’m a drongo cuckoo”).

Distribution & status │ Breeds from eastern India through Myanmar and N Indochina to southern China, and presumably winters south, though the wintering quarters are unknown. Subspecies barussarum is a summer visitor to parts of southern and central China including Guangdong. In Nanling, it is a fairly common summer visitor, recorded at Chengjia, Dadongshan and Ruyang.

Habitat & habits │ Drongo Cuckoos occur singly or in pairs in a variety of wooded habitats including hill forests, where they forage for insects, especially caterpillars. They are nest-parasitic. Host species in Guangdong are unknown.
