The blue-and-white flycatcher (Cyanoptila cyanomelana) is a migratory songbird in the Old World flycatcher family Muscicapidae. The species is also known as the Japanese flycatcher. It breeds in Japan, Korea, and in parts of north eastern China and the Russian Far East. It winters in South East Asia, especially in Vietnam, Cambodia, Thailand, Sumatra and Borneo. This species has been recorded as a vagrant from the Sinharaja Rainforest in Sri Lanka in 2014.
The species was first described in 1829 by Coenraad Jacob Temminck under the binomial name Muscicapa cyanomelana, and was transferred to its own genus Cyanoptila by Edward Blyth in 1847, on the basis of structural differences from other flycatchers, including its wing length and bill dimensions.
The genus name comes from ancient Greek; "kuanos" meaning dark blue, and "ptilon", plumage. The specific cyanomelana also comes from "kuanos", paired with melas, melanos meaning dark, black. Wikipedia →

With luck
About 10% of wildlife watchers report a Blue-and-white Flycatcher sighting in Busan on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April
In that month about 20% of wildlife watchers report a Blue-and-white Flycatcher in Busan on a given day, against under 5% in June to March, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blue-and-white Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 19 cities where we can rate Blue-and-white Flycatcher sightings, Busan ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Daejeon (South Korea, about 10%) and Sendai (Japan, about 10%).
Same family: Muscicapidae
The closest relatives of the Blue-and-white Flycatcher that you can see in Busan (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Daurian Redstart (about 50%) and Blue Rock-Thrush (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue-and-white Flycatcher is recorded against all the birds logged in Busan (12 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.
