The Japanese paradise flycatcher (Terpsiphone atrocaudata), also called the black paradise flycatcher, is a medium-sized paradise flycatcher. It was previously classified with the Old World flycatcher family Muscicapidae, but the paradise-flycatchers, monarch flycatchers and Australasian fantails are now normally grouped with the drongos in the family Dicruridae, which has most of its members in Australasia and tropical southern Asia.
