Two female and one male Przewalski’s horses enjoy their new surroundings at the San Diego Zoo’s Wild Animal Park 23 May 2006. Keepers transferred four mares from one exhibit to another at the San Diego Zoo’s Wild Animal Park as part of a transportation renovation project. The females were released into what was previously a zebra exhibit, where a male Przewalski’s horse awaited. The move is part of a coordinated effort to place the Park’s Asian animals in one region and the African animals in another in order to offer passengers a voyage through the two continents once the new transportation system is completed. The Przewalski’s horse, originally found in Asia, is the only true wild horse in existence. The Przewalski’s horse is an endangered species that became extinct in the wild, but with reproduction and reintroduction programs zoos, including the Wild Animal Park, are succeeding in maintaining this species.
