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 Hanoi on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 82nd most-seen of the 97 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Korean Flycatcher in Hanoi on a given day, against under 5% in May–August and October–March, the lowest months. That is one of Hanoi's wettest months, with about 220 mm of rain against 20 mm in February.
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.
11th of 20
Of the 20 cities where we can rate Korean Flycatcher sightings, Hanoi ranks 11th at under 5%. The best odds are in Hefei (China, about 20%), Jinhua (China, about 10%) and Daejeon (South Korea, about 10%).
GBIF citizen-science records
It is estimated from how often the Korean Flycatcher is recorded against all the birds logged in Hanoi (8 verified sightings), 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.
