When the two young elephants showed up unaccompanied, it was obvious they had lost their mother. Arriving at the park after a long absence, Chastity and her sister were from a family known to spend time in an area with security risks. Their mother's body was never recovered, so it was unclear whether they lost her at the hands of a gun, or from natural causes. Surprisingly, as the orphaned sisters milled about, they didn't stay with the family group their mother had long been affiliated with. Normally, African elephant mother-calf groups are very cohesive, spending 50 to 60% of their time in multi-family "bond groups". But Chastity seemed to shun those previous relationships, and took great interest in a less familiar family, says George Wittemyer of Colorado State University in Fort Collins. These young elephants provided Wittemyer's first close experience of watching an orphan, its social strategy, and its absorption into another group. They prompted him to investigate the behaviour of elephant orphans. There are plenty of them, thanks in no small part to poachers that kill adult elephants for their ivory. Can these parentless animals find their way, and create new families for themselves? There are a lot of unanswered questions, but so far they are proving impressively adaptable.
