The verditer flycatcher (Eumyias thalassinus) is an Old World flycatcher. It is found from the Himalayas through Southeast Asia to Sumatra. This species is named after its distinctive shade of copper-sulphate blue and has a dark patch between the eyes and above the bill base. The adult males are intense blue on all areas of the body, except for the black eye-patch and grey vent. Adult females and sub-adults are lighter blue.
The verditer flycatcher is also interesting among the flycatchers in that they forage above the canopy level and perch on electric wires or exposed tree top branches. This species was earlier placed in the genus Muscicapa and it has been suggested that it is closer to the Niltava flycatchers. Wikipedia →

Possible
About 30% of wildlife watchers report a Verditer Flycatcher sighting in Khao Yai National Park on a given day, based on 748 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 43rd most-seen of the 278 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January and February
In those months about 50% of wildlife watchers report a Verditer Flycatcher in Khao Yai National Park on a given day, against under 5% in April to June, the lowest months. Those are among Khao Yai National Park's driest months, with about 40 mm of rain a month against 330 mm in September.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Verditer Flycatcher sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
3rd of 30
Of the 30 parks where we can rate Verditer Flycatcher sightings, Khao Yai National Park ranks 3rd at about 30%. The best odds are in Royal Manas National Park (Bhutan, about 40%) and Doi Inthanon National Park (Thailand, about 30%).
Same family: Muscicapidae
The closest relatives of the Verditer Flycatcher that you can see in Khao Yai National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Taiga Flycatcher (about 40%), White-rumped Shama (about 40%) and Asian Brown Flycatcher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Verditer Flycatcher is recorded against all the birds logged in Khao Yai National Park (748 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.
