Siskins breed in the northern half of Europe and in southern mountains from the Pyrenees through to Asia Minor and northern Iran as well as discontinuously across Asia to Sakhalin and north Japan. They nest in conifers. Those breeding in eastern and northern Europe, including in north Scotland, move south and southwest in winter, many reaching southern England.
In Britain in the 19th century breeding Siskins were confined mostly to Scotland's native pine forests, the felling of which, and the activities of bird catchers, around the turn of the century led to local declines in population numbers. By the 1930s the declines had stopped and Siskins were now regularly found breeding in northern England. The planting of new conifer plantations after the end of the second World War led to major increases in Siskin numbers in Scotland, Wales and northern England and eventually further south.
In Wiltshire in the 19th century Siskins were known as regular winter visitors, in some years in great numbers, and this has continued to be the case throughout the 20th and early 21st centuries. There have also been regular records of passage migrants, in varying numbers, in both spring and autumn. They were popular cage birds, and occasional sightings of Siskins in summer were thought likely to refer to escaped birds. It was not until the 1980s that breeding was first confirmed in the county. Small, but increasing, numbers have been recorded in every summer since 1988: Birds of Wiltshire recorded them in 35 tetrads, with breeding in five; WTA2 recorded them in 82 tetrads with breeding in 29.
