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 →

Likely
About 40% of wildlife watchers report a Verditer Flycatcher sighting in Royal Manas National Park on a given day, based on 546 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 388 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
March to May
In those months about 50% of wildlife watchers report a Verditer Flycatcher in Royal Manas National Park on a given day, against about 10% in December to February, the lowest months. August and September have too few records to rate.
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.
Yes
Of the 30 parks where we can rate Verditer Flycatcher sightings, Royal Manas National Park has the highest daily chance: about 40%. Next come Doi Inthanon National Park (Thailand, about 30%) and Khao Yai National Park (Thailand, about 30%).
Same family: Muscicapidae
The closest relatives of the Verditer Flycatcher that you can see in Royal Manas National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Blue Whistling-Thrush (about 50%), Oriental Magpie-Robin (about 50%) and White-capped Redstart (about 40%), 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 Royal Manas National Park (546 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.
