Today, two southern white rhino calves played, chased impalas, and met giraffes and African crowned cranes as they explored the expansive African Plains habitat at the San Diego Zoo Safari Park—and at the same time, two greater one-horned rhino calves jogged and gave themselves mud baths in their Asian Savanna habitat.

The San Diego Zoo Safari Park is offering free admission to all active firefighters throughout the month of September, to honor the hard-working men and women who help protect people, wildlife and structures across the region.
