Social Behavior
Although the Ethiopian wolf is primarily a solitary hunter of rodents, it lives in packs that share and defend an exclusive territory. This differs from most larger social carnivores that live in groups for the purpose of hunting cooperatively. In areas with little human interference, packs may average 6 adults, 1–6 yearlings, and 1–13 pups. Typically, packs are an extended family group formed by all males born into the pack during consecutive years and 1–2 females. One study showed that the sex ratio of adult pack members in optimal habitat was biased toward males by a ratio of 2.6:1.
Social gatherings among different packs are more common during the breeding season, and take place in close proximity to the den.
Inter-pack confrontations occur at the territorial border. Ethiopian wolves become highly vocal during these interactions, which invariably end with the smaller group retreating from the larger.
Males do not disperse from their natal pack, while females will leave at the age of two years, joining another pack should a breeding vacancy occur.
