| opmerkingen | Adult female, found dead, skull retained in private collection E Soldaat (E Soldaat). This species has become a major rarity; 21 (60%) records were before 1980, seven between 1980 and 1990 and five between 1990 and 2000, showing an obvious decrease. The absence of long freezing winters could be the main cause. There are two records after 2000, in October 2001 and January 2002. Annual Report 2004. | |
