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.

European Reed Warblers breed from northwest Africa, across Europe to southern Finland, Russia and western Anatolia. They winter in sub-Saharan Africa from Senegal. east to the Red Sea and south to at least Zambia.
In Britain at the end of the 19th century they were breeding in much of Wales and in England from Cornwall to Lacashire and Yorkshire. Since then their range has been expanding northwards in increasing numbers: Bird Atlas 2007-2017 recorded little apparent change in the first half of the 20th century but numbers more than doubling in the last 40 years of the century and increasing by a further 35% between 1995 and 2010.
In Wiltshire in the first half of the 20th century Reed Warblers were reckoned to be not uncommon though certainly much less common than Sedge Warblers, a difference that persisted to the end of the century. Unsurprisingly, the main concentrations are along the valleys of the Thames, both Avons and the Kennet, plus on the Kennet & Avon Canal and at the CWP and Coate Water. Birds of Wiltshire recorded them in 96 tetrads, with breeding in 58. WTA2 found them in 128 tetrads with breeding in 63.
