Unusual Age Structure of the Winter Aggregation of Nyctalus Noctula (Mammalia, Chiroptera) in Kyiv
Abstract We analysed the sex and age composition of a large colony of Nyctalus noctula (605 specimens), wintering in Kyiv, Ukraine. Age was identified in 113 individuals using the method of counting growth layer groups in dentine. Males contained ca. 70 % both in the colony and in the sample of anim...
