Handsome Carlos continues to do well at the Nyaru Menteng Orangutan Rehabilitation Centre, run by the BOS Foundation in Central Kalimantan.
He is in a healthy condition and has been given an ideal body condition score by the veterinarian. Carlos will often kiss squeak and show his displeasure at the technicians when they are around his enclosure, so it is good that he is showing this wild behaviour.
Carlos loves his food and various enrichment given to him by the technicians during the day. He even loves eating all his greens as this video shows.
His favourite enrichment now is ice blocks with orange syrup, honey, and fruit inside, especially on a hot day. Carlos patiently sucks and licks the ice to get to the fruit inside. He also enjoys tied up sacks filled with fruit, and bamboo tubes filled with nuts. Carlos will often gather up his food and put the pieces in his large blue barrel so he can relax in there while he eats. When the fruits and enrichment run out, Carlos will swing on the tyre enrichment and ropes all day into the evening, until he makes a nest to sleep in for the night with leaves and branches.
