Appearance
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.
Naming
This species was earlier placed in the genus "Muscicapa" and it has been suggested that it is closer to the "Niltava" flycatchers.References:
