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.

Long-tailed Tits are found right across Eurasia, from Iberia to China and Japan, and, in Europe, from the Mediterranean to Finno-Scandia. They are sedentary and can suffer high mortality during hard winters, but the size of their broods means that their numbers recover relatively quickly.

The species is widespread throughout most of Great Britain, being absent mainly from some upland areas of mainland Scotland, and from the Northern Isles and the Outer Hebrides. They expanded their breeding distribution only by a marginal 2% between the 1968-72 Breeding Atlas and “Bird Atlas 2007”. Their winter range on the other hand increased by 14% between the 1981-84 Winter Atlas and Bird Atlas 2007-2011 which means that they are now more widespread in winter than in summer.

In Wiltshire, Long-tailed Tits are absent only from large parts of Salisbury Plain and from a few other patches of exposed downland. Birds of Wiltshire recorded them in 615 tetrads, with breeding in 210 of them. WTA2 recorded them in 709 tetrads, with breeding in 469.
