Chimpanzees

From the documentation shown in the HBO docuseries, PETA is pushing for Tonia Haddix and her conspirators to be charged with perjury and obstruction of justice — and for her Animal Welfare Act license to be revoked.

Tonia Haddix had previously claimed Tonka the chimp died of natural causes. His discovery in a Missouri basement gives lie to that claim.

Tonka’s owner, a Missouri woman named Tonia Haddix, says he is dead. PETA doesn’t buy it.

In October, St. Louis Zoo chimpanzee Utamu gave birth to a baby girl. Two months later, the infant — named Raven — is starting to reach exciting milestones, like reaching for objects and trying to mimic chimpanzee vocalizations.

St. Louis Zoo resident Utamu is pregnant. The 18-year-old chimpanzee is expected to give birth this fall. Primate manager Helen Boostrom joins St. Louis on the Air to discuss how a new baby may alter the group dynamics of the facility’s nine chimpanzees.
