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 Nanjing on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 150th most-seen of the 162 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
December
In that month about 10% of wildlife watchers report a Verditer Flycatcher in Nanjing on a given day, against under 5% in January to November, the lowest months. That is one of Nanjing's driest months, with about 40 mm of rain against 240 mm in July.
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.
26th of 41
Of the 41 cities where we can rate Verditer Flycatcher sightings, Nanjing ranks 26th at under 5%. The best odds are in Bhubaneshwar (India, about 20%), Chhatrapati Sambhajinagar (India, about 20%) and Kathmandu (Nepal, about 10%).
Same family: Muscicapidae
The closest relatives of the Verditer Flycatcher that you can see in Nanjing (family Muscicapidae, Old World Flycatchers, Robins, and Chats) are Oriental Magpie-Robin (about 60%), Daurian Redstart (about 30%) and Blue Whistling-Thrush (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 Nanjing (5 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.
