Gorilla charges at man holding his kid

This wasn't that gorilla's kid. The baby was an orphan with the humans raising it. This man was hoping to slowly introduce the baby to a new group of gorillas. However, the baby cried while in his arm that day( probably cause of the presence of the new silverback gorilla) . This made the silverback mock charge the human, forcing him to drop the baby. The silverback then dragged the baby with him and took him into his clan. Unfortunately, this clan did not have any mothers that could breastfeed that baby. The baby eventually died of dehydration a few days later. The narrator said he regretted trying to introduce the baby to the group at such a young age.
