This is the adorable moment a sun bear cub drank milk while sitting on a park ranger's lap in Thailand. Video shows the black baby bear hungrily suckling on the feeding bottle at the Huai Sai Wildlife Breeding Center in Phetchaburi province on September 13. The wildlife ranger said: "The bear cub had to be fed because the mother is not around. The baby wandered away and was separated from its mum". This species lives in tropical forests across Southeast Asia. They are named sun bears because of the patch of coloured fur on their chests, which range in shades from cream to orange.
