The whistling thrushes comprise a genus Myophonus (Myiophoneus) of the Old World flycatcher family Muscicapidae.

They are all medium-sized mostly insectivorous or omnivorous birds. They are all brightly coloured species found in India and southeast Asia. The male is usually blue, and the females are either similar to the male or brown. The brighter blue patches found on the shoulders and sometimes the head, of whistling thrushes, uniquely for a passerine, reflect strongly in the ultraviolet.
