The Verditer Flycatcher is a flycatcher with striking blue-green plumage. It hunts insects in the middle and upper canopy and breeds from the Himalayas into Southeast Asia.
Its plumage is blue-green overall. Males have a dark area between the eye and bill; females and subadults have a pale gray area there and fine bars on the chin.
At Kuankuoshui Nature Reserve in southwestern China, Verditer Flycatchers and Daurian Redstarts bred in 21 houses in an open area within natural forest. Researchers counted nests and breeding pairs during May–July in 1999, 2002, 2004–2006, and 2008–2015, a total of 13 breeding seasons. After the reserve was upgraded, 95% of residents moved outside the reserve. The number of residents fell from 280 to 18, while the number of houses stayed the same.
After residents moved, the number of Verditer Flycatcher breeding pairs was 43, compared with 51 before 2008; the difference was not statistically significant. By contrast, the proportion of nests lost to predation increased from 7.84% to 27.91%. Daurian Redstart breeding pairs declined significantly. Because Verditer Flycatchers nested in houses after people had left, the researchers inferred that the houses themselves served as nesting sites.
An extinction-risk assessment has not been added yet.
During 52 weekly morning surveys at the Tuensang market in Nagaland from May 2009 to April 2010, researchers recorded 32 Verditer Flycatchers (Eumyias thalassinus).
