Redwings breed right across northern Eurasia, from Iceland to eastern Siberia. Redwings from northern Europe winter in the British Isles and adjacent continental countries from Denmark and Germany, southward to North Africa then eastward through other Mediterranean countries to the Black Sea, Asia Minor, the Levant and the southern Caspian region.
    Although primarily winter visitors to Great Britain, Redwings were first recorded nesting in Scotland in 1925 and have nested sporadically there ever since, with a maximum of around 300 pairs in 1972 diminishing to between nine and 38 pairs annually in the last decade of the 20th century. Bird Atlas 2007-2011 recorded them present in the breeding season in seven hundred and eighty 10km squares throughout Great Britain from the Shetland Islands to the Scilly Isles, but the great majority of these were late departing migrants recorded in May. The total did however include confirmed or probable breeding in 25 squares and possible breeding in a further 35 in Scotland, plus two more possibles in northern England.
    In Wiltshire there was an egregious report from an observer who recorded having shot one of a group of three or four Redwings at an unspecified (but by implication in summer) date between 1868 and 1877and subsequently located a nest with young which were raised to maturity. Otherwise all records in Wiltshire have been in winter, when they are seen throughout the county. Birds of Wiltshire recorded them in 66% of the tetrads surveyed. The more comprehensive surveys carried out for WTA2 found them in 91% of tetrads.
