Ethiopian wolves live in close-knit territorial packs numbering between 3 and 13 adults, but individual pack members tend to forage alone (2) (3). Afro-alpine endemics such as the giant molerat (Tachyoryctes macrocephalus
) and three species of grass rats make up the majority of the diet of these wolves; prey are skilfully stalked out in the open or dug out of their burrows (3). All adults gather to patrol and mark the territory at dawn and dusk repelling any intruders, and rest together during the night, usually spent curled up in the open. Strong social bonds exist between members of the group, who greet each other excitedly (3). Male wolves seldom disperse, whereas many females leave their natal pack at maturity to seek a breeding opportunity elsewhere, occasionally 'floating' between established pack ranges (5). The dominant female of each pack gives birth between October and December, to a litter of two to six pups who spend their first three weeks of life inside a closely guarded den (2). Most matings occur with males from neighbouring groups in order to avoid inbreeding (5). Other members of the pack will assist with guarding the den from avian and terrestrial predators. They also regurgitate food for the pups for the first four months of their life, and subordinate females may even suckle the litter (5).
