The yellow-rumped flycatcher, Korean flycatcher or tricolor flycatcher (''Ficedula zanthopygia'') is a species of flycatcher found in Asia. A distinctive species with almost no look-alike other than the narcissus flycatcher. It breeds in eastern Asia including parts of Mongolia, Transbaikal, southern China, Korea and western Japan. They winter in parts of the Malay Peninsula and South Asia. ==Identification==
In all plumages the yellow rump is distinctive. The white supercilium of the male is distinctive, separating it from the narcissus flycatcher and the Chinese flycatcher. Females and first year males are olive grey above with blackish tail. Hartert (1910) treated this as a part of the ''narcissina'' group. Some individuals with yellow supercilium have been considered as hybrids with the narcissus flycatcher. Included in this species complex was the species called Elise's flycatcher, usually treated as a subspecies of the narcissus flycatcher. Both ''elisae'' and ''zanthopygia'' have been observed to breed separately in the same area of oak forest near Peking strengthening the case for their distinctness. There are also clear call and morphological difference between the two. The genus ''Muscicapa'' has been noted to have been polyphyletic and is still in the process of being resolved although the genus ''Ficedula'' is now considered monophyletic with their origins in east Asia, with diversification following climate changes in the Pliocene.
