Résumé :	Migrating Golden Plovers from Fennoscandia, and northern Russia are staging in increasing numbers in Denmark. During a coordinated, countrywide survey around 11 October 2003, a total of 346363 Golden Plovers was Counted in the country (Table 1), or 380000 in total when estimated numbers present at uncovered sites were included. A similar count in October 1993 gave 218000 Golden Plovers counted and a total of 240000 estimated. The results thus suggest an increase between 1993 and 2003 of almost 60%; compared with estimates from the 1970s, the total in 2003 had increased by 117%. The survey in 2003 was timed around full moon and took place 19 days earlier than the full moon count in 1993, but this earlier timing is not believed to have influenced the result to any major extent, so the higher count in 2003 very likely reflects a real increase.The geographical distribution of the Golden Plovers within the country was similar in 1993 and 2003, but the increase in numbers was strongest in the western part (Jutland), cf. Table 2. East of the Great Belt overall numbers did not increase at all. The international criterion of 8000 birds was met at eight of the 13 SPAs designated in part because of staging Golden Plovers (Table 3), while a further four SPAs designated for other reasons held qualifying numbers (Table 4).A total ban on hunting of Golden Plovers since the autumn of 1983 is believed to have affected the number of staging birds by reducing the frequency of disturbances. The Danish counts in 2003 formed part of the international counts of Golden Plovers carried out throughout northern Europe on the same days. A total of 912000 Golden Plovers were counted in Denmark and surrounding countries (Table 5), and the results demonstrate the importance of Denmark for staging Golden Plovers in continental northern Europe in autumn - an importance that has increased substantially during the last decades. Very likely this is an effect both of a changed autumn distribution within northern Europe and of a population increase.
