The Blue Rock Thrush (Monticola solitarius) is a species of chat. This thrush-like Old World flycatcher was formerly placed in the family Turdidae.
This species breeds in southern Europe and northwest Africa, and from central Asia to northern China and Malaysia.
The European, north African and southeast Asian birds are mainly resident, apart from altitudinal movements. Other Asian populations are more migratory, wintering in sub-Saharan Africa, India and southeast Asia. This bird is a very uncommon visitor to northern and western Europe.[wiki]
The Brown Rock Chat or Indian Chat (Cercomela fusca) is a bird in the chat (Saxicolinae) subfamily and is found mainly in northern and central India and only extends slightly into northeastern Pakistan. It is often found on old buildings and rocky areas. It resembles a female Indian Robin but lacks the reddish vent and differs in posture and behaviour apart from being larger. In flight it bears some resemblance to thrushes and redstarts. It feeds on insects, captured mainly on the ground.[wiki]
