A baby gorilla was accidentally killed at a zoo in Canada when it was struck in the head by a door, officials said Thursday. The 2-year-old female gorilla, Eyare, was roaming from room to room when a zookeeper activated the wrong hydraulic door to separate her, according to the Wilder Institute/Calgary Zoo. The accident left the ape with “traumatic head injuries” and veterinary staff administered CPR. The zookeeper “was immediately removed from the workplace following the incident,” the zoo said. The zoo said it launched an investigation into the incident and “doesn’t take these findings lightly.” All zookeepers will undergo retraining to prevent further accidents. “This tragedy has struck us all in the deepest way imaginable,” said Colleen Baird, director of Animal Care, Health and Welfare, in a statement. “Eyare’s short but impactful life brought so much joy to our community, and she will be deeply missed by all. We will do everything we can to prevent future incidents.”
