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 →

Rare
Under 5% of wildlife watchers report a Verditer Flycatcher sighting in Ranthambore National Park on a given day, based on 39 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 174th most-seen of the 251 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.
November and December
In those months about 10% of wildlife watchers report a Verditer Flycatcher in Ranthambore National Park on a given day, against under 5% in January to October, the lowest months. Those are among Ranthambore National Park's driest months, with about 10 mm of rain a month against 270 mm in August.
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.
24th of 30
Of the 30 parks where we can rate Verditer Flycatcher sightings, Ranthambore National Park ranks 24th at under 5%. The best odds are in Royal Manas National Park (Bhutan, about 40%), 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 Ranthambore National Park (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Indian Robin (about 60%), Oriental Magpie-Robin (about 60%) and Black Redstart (about 20%), 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 Ranthambore National Park (39 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.
