What is the name of this bird usually found in Southern India?

The Nilgiri flycatcher is an Old World flycatcher with a very restricted range in the hills of Southern India. It was formerly referred to as the Nilgiri verditer flycatcher because of its similarity to the verditer flycatcher, a winter migrant to the Nilgiris, which, however, has distinct dark lores (details) and a lighter shade of blue. There are two small white patches at the base of the tail. It is found mainly in the higher altitude Shola forests of the Western Ghats and the Nilgiris.

This small and somewhat long-tailed flycatcher is about 13 centimetres (5.1 in). It is dark steely indigo blue with some violet-blue on the forehead. The female is duller with dark brown on the upper parts and dark grey below. Like most flycatchers, it makes sallies (trips) to capture insects and returns to its perch. The song is a series of rich warbling notes while the usual call is a soft nasal chipping 'eep'. They perch upright and produce the chipping note while flicking the tail up and down.
