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.

Lesser Redpolls are endemic to Europe. Originally found only in the British Isles and the Alps, since 1950 they have expanded their range into other countries bordering the North Sea, from northeast France to the southern fringes of Norway and Sweden, and to mountain areas of central Europe.
    In Great Britain they were limited originally to the northern highlands but by 1910 had spread into lowland Britain. Numbers fluctuated throughout the 20th century, with a large increase in the 1960s and 1970s, followed by an even larger decrease which saw the population fall by the turn of the century to barely a sixth of the numbers recorded in the 1988-91 Breeding Atlas. Bird Atlas 2007-2011 recorded a 22% contraction in their British breeding season range since 1988-1991, most of the decline occuring in northeast England, East Anglia and the English midlands. In summer they remain widespread in Scotland, northwest England and Wales but occur only patchily south and east of a line drawn from the Tees to the Severn estuaries. In winter they disperse more widely into the lowland areas.
    Wiltshire lies within the area which Lesser Redpolls largely vacated in the breeding season from the late 20th Century onwards. They were never common  in summer in the county, and the few records that did occur were mostly of late-staying winter visitors or of passage migrants. Birds of Wiltshire recorded them in 17 tetrads in the breeding season, but with breeding confirmed in only one. WTA2 did not record even one instance of breeding, though Lesser Redpolls were recorded in 31 tetrads in the course of the five years of summer fieldwork for the atlas. Their numbers were swollen in winter by birds moving away from colder, higher areas elsewhere in Britain - WTA2 recorded them present in 160 tetrads in Winter.
