Wild dogs in Botswana
Read about them here: Tracking Wild Dogs in Botswanas Okavango Delta
In the early publications about wild dogs, a great deal was made about their social structure being unusual for a mammal: the interpretations of the collective observations of the wild dogs in the Serengeti described them as patrilineally organized social carnivores, where males were described as the caregivers, raising and caring for the young, and the comparatively more philopatric sex, while females were the free-to-disperse sex (liberated so to speak, which I believe was embraced in the U.S. when it was first published at least partly because it was appealing in the socio-political environment of the early 1970s). Even though my research has attempted to correct this misperception (based on incomplete observations of long-term patterns), it persists even today in animal behavior textbooks as an unusual mammalian social system.
