GENEVA (msnbc) The Western Black Rhino of Africa was declared officially extinct Thursday by a leading conservation group. The International Union for Conservation of Nature said that two other subspecies of rhinoceros were close to meeting the same fate. The Northern White Rhino of central Africa is now "possibly extinct" in the wild and the Javan Rhino "probably extinct" in Vietnam, after poachers killed the last animal there in 2010. A small but declining population survives on the Indonesian island of Java.
