The Ethiopian wolf (Canis simensis) is a carnivorous mammal of the family Caniae. It is also known as the Abyssinian wolf, red jackal, red fox, Simien fox or Simien jackal). The numerous names reflect previous uncertainty about its taxonomic position, but it is now thought to be related to the wolves of the genus Canis rather than the foxes it superficially resembles. The Ethiopian wolf is found in the Afro-alpine regions of Ethiopia, about 10,000 feet (3,000 meters) above sea level. It is the most endangered canid, with only about seven populations remaining, totalling roughly 550 adults. The largest population is found in the Bale Mountains in southern Ethiopia, although there are also smaller populations in the Simien Mountains in the north of the country, and in a few other areas. Claudio Sillero-Zubiri at the University of Oxford is the zoologist most closely associated with efforts to save this species of wolf, particularly with his work for an oral rabies vaccine to protect them from the disease passed from local dogs. His work is supported by the Born Free Foundation. A rabies outbreak in 1990 reduced the largest known population, found in the Bale Mountains National Park, from about 440 wolves to less than 160 in only two weeks.
