Most zoos have signs that say something like “Don’t feed the animals” but have you ever seen a sign that tells you not to provoke them?
The Henry Doorly Zoo & Aquarium in Omaha, Nebraska might need one after this incident of a gorilla cracking the glass, which was the only thing separating it from a family of onlookers:
You can see the look of dumbfounded expression on the family members’ faces as the gorilla slams into the glass:
Seconds before it charged the family, a little girl pounded her chest at the animals. You can see her reflexion in the GIF below:
When two tribes meet, the two males will sometimes partake in a fight to the death, so in order to avoid this they will perform a series of acts to scare off their competitor by appearing stronger. Chest-beating and kicking with one leg are some of the displays they make.
According to the zoo keeper, this is not the first time a gorilla has cracked a glass window at the zoo. Looks like a sign instructing visitors not to provoke the gorillas might be a good idea.
