The name is normally applied to the more robust ground-feeding flycatchers found in Europe and Asia.
These species were formerly classified as members of the thrush family (Turdidae), but now placed in the Old World flycatcher family (Muscicapidae).
Chats make up most of the sub-family Saxicolinae, or commonly known as bush chat.

The European robin or simply robin belongs to the Chat sub-family.
