Zappey's flycatcher (Cyanoptila cumatilis) is a songbird in the Old World flycatcher family Muscicapidae. It is migratory, breeding in central China from central Sichuan northeast to the mountains west of Beijing, and wintering south to the Malay Peninsula, Sumatra, and Java. It closely similar to, and was formerly considered to be conspecific with, the blue-and-white flycatcher, which breeds further east from northeastern China east to Japan.
It is a large flycatcher, 17 cm long. The males have slightly greenish turquoise-blue upperparts, greenish-black face and upper breast, and pure white underparts, faintly greyish on the flanks; the tail is similar colour to the back, with two small white patches on the sides at the base of the tail. Zappey's flycatcher differs from blue-and-white flycatcher in the greener-toned blue and black, compared to the more intense dark blue and black of its relative.
The females are similar pattern, but greyish-brown rather than blue, and have a white throat. Immature (yearling) males are intermediate, with blue wings, rump, and tail like adult males, but grey-brown head and mantle and white throat like females. The bill and legs are dark grey to black, and the eyes brown. Wikipedia →

Rare
Under 5% of wildlife watchers report a Zappey's Flycatcher sighting in Khao Sok National Park on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 163rd most-seen of the 213 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.
February and March
In those months about 10% of wildlife watchers report a Zappey's Flycatcher in Khao Sok National Park on a given day, against under 5% in April to January, the lowest months. Those are among Khao Sok National Park's driest months, with about 45 mm of rain a month against 280 mm in October.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Zappey's 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.
Yes
Of the 2 parks where we can rate Zappey's Flycatcher sightings, Khao Sok National Park has the highest daily chance: under 5%. Next come Doi Inthanon National Park (Thailand, under 5%).
Same family: Muscicapidae
The closest relatives of the Zappey's Flycatcher that you can see in Khao Sok National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are White-rumped Shama (about 60%), Asian Brown Flycatcher (about 40%) and Oriental Magpie-Robin (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Zappey's Flycatcher is recorded against all the birds logged in Khao Sok 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.
