INDIANAPOLIS -- The Indianapolis Zoo is preparing for a baby! The zoo announced Wednesday that Sirih, a 22-year-old Sumatran orangutan is due this spring.
Her pregnancy is a first for the Simon Skjodt International Orangutan Center.
This will be Sirih's second baby. She had a daughter in 2003 when she lived at the Frankfurt Zoo in Germany.
According to the Indianapolis Zoo, orangutans have the longest interbirth intervals of all land mammals, and mothers bond very closely with their offspring. After the birth, Sirih will spend seven to nine years with the baby, as he or she learns what to eat, how to climb, build nests and socialize.
