...populations in California and Oklahoma could be described as obsessively social: individuals were rarely alone. If a single individual was observed, unless it was the last member of a group to depart a particular area, there was another one somewhere nearby.

Individuals return to natal areas to visit with parents and former group members, and also visit siblings living elsewhere, sometimes moving in with them. They were attracted to each other and often seemed as if they "wanted" to be a part of what others were doing.
