Map explanation

This map shows where changes occurred in the relative abundance 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.

Yellow Wagtails breed from North Africa and western Europe right across Eurasia to western Alaska. They winter in Africa (mostly south of the Sahara), the Indian subcontinent  and southeast Asia down to north Australia. Not surprisingly, given their wide distribution, there are many subspecies (Handbook of the Birds of the World - Lynx Edicions - lists 17). Most of those seen in Britain belong to the race Motacilla flava flavissima which are also found in coastal areas of mainland Europe from Norway to France. The nominate race, M. flava (" Blue-Headed Yellow Wagtail"), the main continental race, also occurs increasingly in Britain, interbreeding with M.f.flavissima. There has been at least one British record of a pure bred pair successfully nesting.
    In Britain they are found mainly in a few scattered areas on the east coast of southern Scotland and then down the eastern side of England with the densest concentrations in East Yorkshire, Lincolnshire, the Fens, the Norfolk Broads and the coastal marshes of Essex and Kent. Elsewhere there are smaller populations on the Welsh borders and across central England. This follows a significant range contraction in the last half-century - Bird Atlas 2007-2011 recorded a 31% reduction since the 1968-72 Breeding Atlas, mainly from northwest England, the West Midlands, parts of East Anglia and the southern counties from Devon across to Sussex. This range reduction has been accompanied by a 72% population reduction mainly attributed to habitat loss caused by changes in agricultural methods.
    In Wiltshire, Yellow Wagtails were reportedly common in the 19th century, but only "fairly common" in the first half of the 20th century and "far from common" in the 1950s. Birds of Wiltshire recorded them in 127 tetrads, almost all to the north of Salisbury Plain, with breeding reported from 64 tetrads, WTA2 recorded them in 108 tetrads, still almost entirely in the north half of the county, with breeding in only 43
