Malayan sun bears are omnivorous. They eat small vertebrates such as lizards and nesting birds and fruit. They are also very fond of honey. Two or three cubs are usually born after a gestation period of 96 days. The young, usually weighing 10-15 ounces each, are suckled for about 18 months.
Females reach sexual maturity at about three years and males at four years.
These bears live 25 to 38 years in captivity. Jun came to the Honolulu Zoo as a cub, from Malaysia in July of 1975.He is renown in the zoo world for his ability to produce viable offspring. The nation's zoo sun bear population is declining, less than sixty, with twice as many females as males, and only one birth since 1995. As you can see, ours is a significant contribution to the dwindling sun bear population. When observing Jun on a visit to our zoo, you may notice his poor eyesight.
