Cyornis

Cyornis is a genus of birds in the Old World flycatcher family Muscicapidae most of which are native to Southeast Asia.

Taxonomy
The genus Cyornis was introduced by the English zoologist Edward Blyth in 1843. He listed three species in the genus but did not specify which he considered to be the type species. The type was subsequently designated by George Gray in 1855 as Phoenicura rubeculoides Vigors, 1831, the blue-throated blue flycatcher. The genus name combines the Ancient Greek kuanos meaning "dark-blue" with ornis meaning "bird".

The genus contains the following 32 species:

Seven of the above species, all with "jungle flycatcher" in their English names, were previously placed in the genus Rhinomyias but were moved to Cyornis based on the results of a 2010 molecular phylogenetic study. There are also "jungle flycatchers" in the genus Vauriella.
