Résumé :	The species conservation programme for the Montagu's Harrier in Schleswig-Holstein has been co-ordinated since 1997 by the State Hunting Society. The Environmental Ministry of Schleswig-Holstein has published annual reports on the programme since 1997. The reports contain information on breeding numbers that do not agree with my own studies on this species. According to my data, the Montagu's Harrier population in Schleswig-Holstein decreased slightly during the 25 year period from 1966 to 1996 (not statistically significant). According to the above mentioned reports a dense local population of 13-14 pairs of Montagu's Harrier bred in a study area in Nordfriesland (TK 1118) in 1999 (Fig. 1., 1999 F). During a survey I carried out in the same study area in the same year, only 6-8 pairs were found to be breeding (Fig. 1, 1999 B). I conclude that the data presented in the above mentioned reports should only be used after careful checking and analysis.
