“…The temporary decline of whitetailed eagle, Eurasian sparrowhawk and osprey (Pandion haliaetus) as a result of biocides is comprehensively documented. Reference is made to work by Oehme (1987), Oehme and Manowsky (1991), Kenntner (2002), Helander et al (2002) on the white-tailed eagle; Bednarek et al (1975), Newton (1986), Gedeon and Oehme (1993), Weber et al (1997), Denker et al (2001) on Eurasian sparrowhawk and Wiemeyer et al (1988), Weber et al (2003) on the osprey. In comparison, species which hunt small mammals such as common kestrel (Falco tinnunculus), Montagu's harrier (Circus pygargus), red kite (Milvus milvus) and lesser spotted eagle (Aquila pomarina), are and were contaminated to a much lesser extent, biocide burdens being more than an order of magnitude smaller and thus uncritical (Conrad 1977;Ho¨lker 2002;Weber et al 1996Weber et al , 1998.…”
