A gorilla at the Calgary Zoo has died.

The Wilder Institute/Zoo in Calgary announced in a news release Tuesday that a member of its western lowland gorilla troop has died suddenly.

The zoo plans to share more details at a press conference Tuesday afternoon. CTV News Calgary will broadcast the event live.

This is the third animal death announced in the past week, with the zoo sharing news of the deaths of two of its elderly animals on Friday.

Callie, an 18-year-old Rocky Mountain bighorn sheep, was euthanized last month due to “age-related degenerative changes” that were affecting her quality of life.

The zoo also said goodbye to Wilbur, a wild boar featured in the Exploration Asia exhibit, who was also euthanized due to degenerative changes.

This is a last minute update. More details to come…
