Abstract:
Elephants in the wild live in herds of related females from several generations. Zoos, therefore, tend to house elephants in female groups, consisting where possible of related individuals. This type of group structure is very beneficial as it allows group members to experience events such as births in the group, and means that natural social interactions can take place between the group members. The behavior of four related female Asian elephants (Elephas maximus) at Dublin Zoo was recorded before and after the birth of a calf, to examine what effects it would have on the behavior and associations in the elephant group. The mother of the calf significantly decreased the amount of time she spent walking after the birth and the aunt of the calf showed significant decreases in both walking and standing. The mother spent the majority of her time closest to her calf after the birth, but the proportion of time she spent with each of the other individuals in the group did not change. The associations of the aunt also did not change after the birth. The older sister of the newborn calf increased the proportion of time she spent nearest to her mother after the calf was born, and reduced the time she spent close to another young elephant in the group. The new calf seems to have been successfully assimilated into the elephant group. Zoo Biol 31:442–452, 2012. © 2011 Wiley Periodicals, Inc.
