Eirina, an 8-year-old Sumatran orangutan, is the Denver's Zoo's newest resident and she is already making friends fast, upon arriving from Germany’s Zoo Dortmund last Thursday. It could be Eirina's playful personality that immediately attracted Bernas, a 14-year-old male orangutan, who was already living at the Denver Zoo. Zookeepers introduced the two primates over the weekend, and not only was Eirina offering Bernas treats, but when the two first met face-to-face, they warmly greeted each other with a big hug. It's hopeful that the two orangutans will eventually breed, which would be awesome since Sumatran orangutans are currently listed as a critically endangered species. As of now, there are only an estimated 9,200 of this type of orangutan living in the wild, and they can only be found on the island of Sumatra in Indonesia. Their survival is being threatened because of habitat loss due to human activities such as mining, hunting, timber clearing, and forest fires. According to the Denver Zoo, if these types of things continue to occur, it's possible that orangutans may be extinct in the wild within a decade.

You can visit Eirina and Bernas in the Great Apes building at the Denver Zoo. The zoo is open year-round, from 9 a.m. to 5 p.m. daily until November 1, and then from 10 a.m. to 4 p.m. starting November 2 through February 28.
