Map explanation

This map shows where changes occurred in the breeding season distribution of the species in Wiltshire between 1995-2000 and 2007-2012, as revealed by the fieldwork for Birds of Wiltshire (Wiltshire Ornithological Society 2007) and the shared fieldwork for Bird Atlas 2007-2011 (BTO 2013) and for Wiltshire Tetrad Atlas 2007-2012.

Dunnocks breed in Asia Minor across to Iran but otherwise only in Europe east to the Urals, excluding Iceland and also much of Ukraine and the southern parts of Mediterranean countries. North and east European Dunnocks migrate south in winter, some reaching Mediterranean islands and north Africa. British Dunnocks on the other hand are sedentary.
    In Britain they are absent only from treeless stretches of the Scottish Highlands and from parts of the Outer Hebrides and the Northern Isles, and there has been little change in range since the 1968-72 Breeding Atlas.There was however a 46% population reduction in the last quarter of the 20th century, the causes of which remain little understood. There has been some recovery in numbers since then and they remain one of the country's commonest birds.
    In Wiltshire they are common and widespread, absent only from a few areas, such as the open expanses of Salisbury Plain, where their favoured habitat - low dense cover - is missing. Birds of Wiltshire recorded them in 839 tetrads with breeding in 594 of them. WTA2 recorded them in 853 tetrads with breeding in 481.
