Range extension of Long-tailed Rosefinch into Western Palearctic

Published on 01 October 1999 in Main articles

ABSTRACT Records of Long-tailed Rosefinch Uragus sibiricus in the Western Palearctic are generally attributed to escapes from captivity. The species has, however, greatly expanded its Siberian range and now occurs during nomadic movements as far west as the eastern fringes of the Western Palearctic in Russia, where it has also bred. Observers are therefore alerted to the possibility of genuine vagrancy in other parts of Europe.ccording to Dement’ev & Gladkov (1954), the western limit of the range of the Long-tailed Rosefinch Uragus sibiricus (nominate sibiricus) runs roughly from Ust’-Kamenogorsk (southwest Altai, Kazakhstan) to Barnaul, Novosibirsk and Tomsk; from there, the limit continues north and east, reaching Yeniseysk and then turning south to Nizhneudinsk and Irkutsk (Lake Baykal) before ­ as reported by Stepanyan (1990) ­ contin-uing east through the Vitimskoe plateau at 55°N (fig. 1). See also small-scale map of World range in Clement (1993). Recent summaries have indicated an extension farther to the north and west: to the upper Vasyugan river (roughly 57°50’N, 77°E), Surgut in the Ob’ river basin (Tyumen’ region), and Uvat in the Irtysh valley, 125 km north of Tobol’sk (Ivanov 1976; Stepanyan 1990: fig. 1).
