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 green-backed flycatcher. Females and first year males are olive grey above with blackish tail.
Hartert (1910) treated this species as a member 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 differences... Wikipedia →

Rare
Under 5% of wildlife watchers report a Korean Flycatcher sighting in Cuc Phuong National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 102nd most-seen of the 159 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Korean Flycatcher in Cuc Phuong National Park on a given day, against under 5% in June and September–March, the lowest months. July has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Korean Flycatcher sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 9
Of the 9 parks where we can rate Korean Flycatcher sightings, Cuc Phuong National Park ranks 5th at under 5%. The best odds are in Khao Luang National Park (Thailand, about 10%), Way Kambas National Park (Indonesia, about 10%) and Kaeng Krachan National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Korean Flycatcher is recorded against all the birds logged in Cuc Phuong National Park (17 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
