They appear to beg for food from visitors, making eye contact with the person holding the camera and even standing on their hind legs as they plead for pieces of fruit.
The video was recorded by the Scorpion Wildlife Trade Monitoring Group, an Indonesia-based welfare organization that monitors wildlife in zoos around the country. One of the team members who visited can be seen holding a papaya, which he breaks up and throws to the eager animals.
According to Scorpion, which called the zoo "horrific," the bears have been like this for months. The group has posted several videos over the past year of the same starving bears, and claims it's called upon the zoo to improve their welfare or shut down, to no effect.
In one haunting clip posted back in June, a skinny male bear can be seen stretching himself himself up to beg for food from visitors, his ribs clearly visible through his black coat.
