Tawny Owls are resident in north-west Africa, all of Europe - except Iceland, Ireland, northern and central Fenno-Scandia and northern Russia – western Siberia, parts of the Middle East and along the Himalayas east to China, Korea and Taiwan. They occur widely throughout Great Britain except in the northern and some of the western islands of Scotland.
    Being nocturnal they are poorly covered by most surveys but such evidence as is available suggests a generally stable British population with some moderate decline in Scotland and south-west England since 1970. In Wiltshire they remain widespread with only a slight decrease between Birds of Wiltshire (where they were recorded in 338 tetrads, with breeding in 167) and WTA2 (298 tetrads, breeding in 162).
