The male has black upperparts, a white eyebrow and wing patch, and yellow underparts and rump. The female is brown above with yellow underparts and rump.
Among the declining species in the South Korean study, Yellow-rumped Flycatcher was one of five estimated to occur in fewer areas at the start.
For all five, the estimated share of survey areas where they were present fell by more than half between the two periods.
An extinction-risk assessment has not been added yet.
