Yellow-rumped Flycatcher

The yellow-rumped flycatcher (Ficedula zanthopygia), also known as Korean flycatcher or tricolor flycatcher, is a species of flycatcher found in eastern 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.

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. Males have black upperparts with a white supercilium and wingpatch, rich yellow underparts and rump. Females are greyish or olive-green above, paler below, with wingbar and yellow rump. They may show yellow on the throat.
