Social organization in the African bat, Myotis boccagei

In northeastern Gabon (lat.: 0.4 degrees north, long.: 12.5), the social organization of the vespertilionid bat Myotis boccagei was studied. In four groups, all individuals (55) were marked and monitored regularly for 38 months. The basic social organization in Myotis boccagei is the "harem". In each group, a single adult male is invariably found, accompanied by from 2 to 7 adult females and recent young.
