Research on African Elephants shows that bulls can be sociable,
at least for a period of time:
"Male elephants have a reputation as loners. But in Amboseli National Park in Kenya, where the longest-running studies on male elephants have been conducted, bulls have been observed to have a best friend with whom they associate for years. Another study, in Botswana, found that younger males seek out older males and learn social behaviors from them. In my previous field seasons at Mushara, I’d noticed that males had not just one close buddy but several, and that these large groups of males of mixed ages persisted for many years. Of the 150 bulls that we were monitoring, the group I was particularly interested in, which I called the “boys’ club,” comprised up to 15 individuals—a dominant bull and his entourage. Bulls of all ages appeared remarkably close, physically demonstrating their friendship."
