Taxonomy
Eight races are usually recognised: columbarius, the Taiga Merlin, in Alaska and northern Canada, suckleyi from British Columbia to northern California and richardsonii in the Great Plains. The large and dark F.c.subaesalon breeds in Iceland and the Faroes and winters in the British Isles, rarely on European coasts from Norway to France, aesalon breeds from Europe to western Siberia and the paler insignis breeds in eastern Siberia and winters in Japan and China. Another pale race pallidus breeds in west-central Asia, lymani in the eastern Altai, Tien Shan and western China.
