“…According to these authors, the majority of movements of the young do not exceed a few hundred kilometres. However, there have been some cases in which young Kestrels covered distances longer than 1000 km (Mead et al 1993, Clark et al 2001 or even 3000 km (Appleton et al 1997). There are two interesting recoveries of the birds found in autumn as the adults in France (860 km, 1524 km), mentioned while describing the adult birds' movements.…”

In Poland, the Kestrel is an uncommon bird during the winter time. It rarely winters in the eastern part of the country; however, the reported numbers of regular wintering cases increase towards the southwest. The aims of this study were: to analyse the wintering area of Kestrels nesting in Poland, to compare distances covered by the birds migrating for the first time in their life to their movements in the following years, and to determine the origin of Kestrels wintering in Poland. The material for the analysis comprised 171 recoveries of the birds ringed in Poland or recorded in Poland but ringed abroad within the years 1931-2001. Out of 48 adult Kestrels ringed or recovered during both migration periods (autumn and spring), the great majority were recorded in Poland; only 2 birds were found as adult ones in France and 1 in Ukraine. We obtained 32 recoveries of Kestrels ringed in Poland as chicks or as individuals in their first year of life and recorded again during their first migration season (autumn-spring). Five of them were recorded outside the country. In Poland, there were reported 94 Kestrels that had been ringed abroad. Those birds came from Finland, Sweden, Norway, Germany, Denmark, Slovakia, the Czech Republic and Ukraine. These data show that mainly Kestrels nesting in the north of the continent migrate across Poland and some of them winter here as well. A great majority of recoveries referred to Kestrels ringed in Finland. These birds also came to Poland from Germany and from the areas located to the southwest of Poland.

This is the 64 th annual report of the British Trust for Ornithology's Ringing Scheme presenting work carried out and data received in 2000. Ringing birds is an important tool for conservation and research, providing information on survival, productivity and movements of birds. Much progress has been made in developing Integrated Population Monitoring (IPM) models to identify key aspects of a species' biology. Studies on Marsh and Willow Tits and on Bullfinches focussed on developing models for these species, which are of particular conservation concern. A further study described some advances in statistical theory that can be used in IPM models. A study of Redshank movements showed differences before and after closure of a tidal barrage in Cardiff Bay in south Wales. Data collected by the Constant Effort Sites (CES) Scheme showed mixed fortunes for breeding birds. Adult numbers increased significantly for four species (Long-tailed Tit, Sedge Warbler, Reed Warbler and Whitethroat) and four species showed significant declines (Linnet, Garden Warbler, Blackcap and Willow Warbler). Similarly, productivity increased significantly for three species (Blue Tit, Blackcap and Willow Warbler) and decreased significantly for three species (Reed Warbler, Chaffinch and Bullfinch). Initial work on a project to develop standard CES methods across Europe is described. 101 datasets for 43 species were submitted for the Retrapping Adults for Survival (RAS) Project. The number of birds ringed in 2000 (734,235) was 8% lower than the five-year mean 1995-1999. The recovery total (10,912) was 6% below the mean of the previous five years (1995)(1996)(1997)(1998)(1999). Recoveries of 156 BTO-ringed birds and 81 birds ringed abroad are presented in the report, including a number of significant movements of an unusual nature. Particularly noteworthy are the first report abroad of a BTO-ringed Shorelark, the first BTO-ringed Whinchat to be recovered on the wintering grounds and a Great Tit that was ringed at Rybachiy in Russia in September 1999 and recaught in Cleveland in February the following year.
