Released Gibbons Have Baby
21 October 2014
We are very excited to announce that our released gibbons, Baray and Saranik, gave birth to their first baby earlier this month! At the end of last year, a pair of endangered pileated gibbons that were raised at Phnom Tamao Wildlife Rescue Center (PTWRC), were successfully rehabilitated and reintroduced into the protected forest of Angkor Archaeological Park. Since their release, the gibbons have been closely monitored, and it has been quite remarkable how quickly they have adapted to their new life in the forest. They remain a closely bonded pair, are completely self-reliant and now the latest addition to their family is another sign that they have settled into their new home!
Ancient Angkor’s mysterious decline may have been slow, not sudden. Sediment analyses suggest that the city’s elite gradually abandoned the Khmer Empire capital. By Bruce Bower, 3:00pm, February 25, 2019.
