Colours of soft parts as in C. t. tickelliae.
Measurements. Wing 67 to 73 mm.

Nidification and Habits differ in no way from those of Tickell's Blue Flycatcher. It is a resident bird wherever found and breeds from the level of the plains to some 4,000 or 5,000 feet. In winter it wanders about a good deal in the open and is therefore more conspicuous but it is nowhere more than locally migratory.
