Dippers are found from northwest Africa and western Europe, across central Asia to central China. They are specialist feeders mostly on aquatic invertebrates which they catch by diving and swimming underwater in fast flowing streams or rivers with weirs.
In Britain they are most numerous in Scotland, Wales and in northern and southwest England, and are absent from lowland areas in central, southern and eastern England. They are sedentary and consequently there is little difference between their summer and winter distribution maps, though their numbers have been thinning out. Annual monitoring data revealed a 30% population decline between 1970 and 2010, believed to be the result of acidification of streams by run-off from conifer plantations leading to a reduction in the invertebtate populations.
In Wiltshire Dippers were first recorded in the 1880s and from then until the mid 1940s they gradually expanded their range, mostly along tributaries of the Bristol Avon and the Salisbury Avon. Since 1950 they have been in decline, in line with the national trend. Birds of Wiltshire recorded them in 18 tetrads, with breeding in 15 of them along two tributaries of the Bristol Avon (the River Frome and the By Brook). WTA2 found them in 12 tetrads with breeding confirmed only at five separate sites on the By Brook . There was also evidence of probable breeding at one of three locations on the River Nadder.
