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).

British Birds – how it works
BB 2000 Ltd, the company that owns and publishes British Birds, is run by a board of directors, all of whom are volunteers. The company employs two full time staff – Roger Riddington is the journal’s editor while Hazel Jenner manages subscriptions and administration – and three part-time design/editorial staff.
The company is wholly owned by The British Birds Charitable Trust (BBCT, registered charity no. 1089422). Neither the company directors nor the trustees are paid for their services, providing their time and enthusiasm because they passionately believe in the value of BB. The Company is managed with a view to making a small profit which can be donated to the Trust to help fund its charitable work.
Over the past six years, this, combined with donations from other sources, has enabled the Trust to give almost £40,000 support to a variety of conservation and educational projects ranging from rat eradication on seabird islands to the study of cuckoo migration, as well as assisting young birders develop their interest.
A full list of projects is given here. The Trust is seeking to expand its charitable endeavours and would welcome donations from like-minded organisations and individuals.
