The Rockhampton Regional Council has announced that a young chimpanzee named Cassie will be relocated to a different facility following unsuccessful attempts to reunite her with her mother after a challenging start to life. Cassie was born at the Rockhampton Zoo in June but suffered a broken leg when her mother accidentally dropped her just hours after giving birth.

Zoo staff provided intensive care for Cassie, striving to replicate the natural behaviors typical of chimpanzee interactions. After her recovery, zookeepers tried to reintroduce her to her mother, Sile, and another female from the troop, Mary. Unfortunately, both females exhibited aggressive behavior towards Cassie, resulting in bruises and bite marks on the young chimp.

Following these incidents, the zoo’s management indicated they would consult with experts to determine the best course of action for Cassie. In a social media update, Jo Thrower, the primate team leader, shared that discussions with specialists from Australia and Europe led to the conclusion that Cassie would benefit from joining a new troop.

Thrower emphasized the importance of Cassie being raised in an environment with other chimpanzees, stating that remaining in human care could lead her to develop a perception of herself as human, which could create challenges in her future integration with other chimps. “The sooner we can arrange this move, the better it will be for her,” she noted.

While acknowledging the affection the Rockhampton community has for Cassie, Thrower reiterated that the priority must be her welfare, as staying with the current troop could result in further harm to her. Cassie has been progressing well developmentally, meeting all necessary milestones.

The zoo has not yet disclosed the specific facility to which Cassie will be transferred, as it is still exploring options and plans to inform the public once a decision has been finalized. Cassie’s name honors both a long-time resident chimpanzee named Cassius, who lived at the Rockhampton Zoo for nearly 40 years, and a local woman named Cassie who provided colostrum to support the young chimp during her initial weeks after birth.

Currently, Cassie is part of a troop consisting of seven chimps, including four males aged between six and 30 years and three females aged from eight to 23 years.
