Zappey's Flycatcher

Zappey's flycatcher is a large, 17 cm songbird of the Old World flycatcher family. It is migratory, breeding in central China from central Sichuan north-east to the mountains west of Beijing, and wintering south to the Malay Peninsula, Sumatra and Java. (Wikipedia, general species account)

It is closely similar to the blue-and-white flycatcher, with which it was formerly considered conspecific and which breeds further east from north-eastern China to Japan. The males have slightly greenish turquoise-blue upperparts, a greenish-black face and upper breast and pure white underparts, faintly greyish on the flanks. (Wikipedia, general species account)
