Bornean sun bear cub, Duma, calls to his mom while exploring his Sun Bear Forest exhibit at the San Diego Zoo on June 28. This is the first time the four-month old cub, born Feb. 17, has left his den to explore the outdoor exhibit. Bornean sun bears are rarely seen in zoos, and Duma is the first ever to be born at the San Diego Zoo. Bornean sun bears are some of the smallest bears in the world, and are threatened with extinction in the wild.
