A wildlife charity says rare Ethiopian wolves are making a comeback after losses from disease and drought.

The Britain-based Born Free Foundation said Friday that the birth of 60 new wolf pups has been recently recorded in the stronghold of the species in the Bale mountains of southern Ethiopia.

The foundation says there are fewer than 500 Ethiopian wolves remaining in a few mountain enclaves. The largest enclave is the Bale range, where the have endured deadly outbreaks of rabies and canine distemper virus, as well as , in the last three years.

A loss of habitat also threatens the wolf species as people move to the Ethiopian highlands because of their high rainfall and that is suitable for agriculture.
