Happy International Tiger Day—also known as Global Tiger Day—on July 29! For this very special episode of Amazing Wildlife, Rick and Marco are joined by Lori Hieber, lead wildlife care specialist for the primate and carnivore team. Lori, who has worked with tigers for 15 years, describes the different subspecies of tigers and their various sizes. In addition, Lori tells us more about the four tigers currently at the San Diego Zoo Safari Park, and how the team can identify them through their unique markings and personalities.
