Copulation outside the pack occurs with males of all rank, but those within the pack occur only between the dominant male and female. Prior to copulation, the dominant female increases her rate of scent marking, play soliciting, food begging towards the dominant male, and aggressive behavior towards subordinate females. Ethiopian wolves mate over a period of 3-5 days, involving a copulation tie that lasts up to 15 minutes. Ethiopian wolf packs are territorial. C. simensis travels in packs to patrol its territory.
Packs maintain the boundaries of their territories by scent marking and vocalization.
Home ranges of packs are small for a canid of its size. Skirmishes between neighboring packs are frequent. Canis simensis makes several types of vocalization. Alarm calls are emitted at the sight or scent of man, dogs, or unfamiliar wolves. Canid Specialist Group and Wolf Specialist Group, the World Conservation Union, Gland, Switzerland.
