An investigation by the Calgary Zoo determined a 2-year-old female western lowland gorilla named Eyare died from "human error."

A 2-year-old female western lowland gorilla died at the Calgary Zoo after sustaining head injuries from the closing door, zoo officials said. This marks the third accidental animal death due to human error in recent years at the zoo.

Eyare, a 2-year-old western lowland gorilla, died last week after being struck in the head by a hydraulic door a staff member accidentally activated, the zoo said in a statement Wednesday. The worker was trying to separate Eyare from other members of the gorilla troop for a solo training session.

After the European Union opened a competition investigation into Corning earlier this month, citing concerns over alleged exclusive dealing, the Gorilla Glass maker has offered a raft of changes to its contract clauses aimed at settling the probe.

A young, two-year-old western lowland gorilla has died from traumatic head injuries sustained by a hydraulic door at a Canadian zoo in Alberta, on November 12th. Information about the death was just released to the press on November 23rd.
