The BTO Bird Atlas shows the stonechat is a bird of the north and west of the British Isles.
The stonechat's scientific name is Saxicola rubicola, meaning rock-dwelling bramble-dweller. Its common name obviously comes from its call, as described by Thomas Bewick in A History of British Birds, although he was hedging his bets.
Bewick also gave its other names of stone-smith and moor-titling.
