The video shows a gentle gorilla inside a zoo enclosure checking on an injured bird before trying to help it fly. At the start of the video, a medium-sized gorilla is seen making his way through the lawn. Some zoo visitors are heard speaking in the background.After a few seconds, the visitors realise the gorilla was checking out an injured bird that was lying on the ground. The large primate bends down and checks on the bird first. After a few seconds, it gives the bird a nudge and helps it to get going.
