Gorillas' Viral Window Bangs at Abandoned Bristol Zoo

A troop of western lowland gorillas at Bristol Zoo's old Clifton site went viral after urban explorers filmed them pounding on enclosure windows. This occurred after the zoo closed to visitors in 2022, leaving the animals without public interaction for over a year.

The eight gorillas, including the 45-year-old silverback Jock, were eventually relocated to a new Central African forest habitat at Bristol Zoo Project earlier this month. Jock, born in France in 1981, was a significant participant in Europe's breeding program for the critically endangered species.
