The Old World flycatchers are a large family, the Muscicapidae, of small passerine birds restricted to the Old World, with the exception of several vagrants and two species, bluethroat and northern wheatear, found also in North America. These are mainly small arboreal insectivores, many of which, as the name implies, take their prey on the wing. The family is relatively large and includes 351 species which are divided into 54 genera.

The northern wheatear or wheatear is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher, Muscicapidae. It is the most widespread member of the wheatear genus Oenanthe in Europe and North and Central Asia.
