Primate Diary: Observing Orangutans in the Wild

Two young orangutans play in the trees in Borneo at the Tuanan Orangutan Research Station.
As two orangutan infants tussled in the trees, curator of primates Meredith Bastian and primate keeper Alex Reddy looked on in awe. Over the summer, they traveled to Central Kalimantan in Indonesian Borneo to follow these great apes in their native habitat.

Why did you travel to the Tuanan Orangutan Research Station?

Bastian: The Tuanan camp and forest hold so many wonderful memories for me, and I felt immediately at home back in the forest. In 2003, I helped train the first field assistants in wild orangutan collection data and conducted fieldwork from 2003 to 2007. I am so thankful to have been able to return to my second home in the swamps of Indonesia. Having lived and worked there for so many years, this was a real homecoming for me.

I was so pleased to be able to bring Alex and to see her thoroughly enjoy the forest and follow wild Bornean orangutans for the first time. It is useful for keepers to have an understanding of orangutan life in the wild, as she can integrate what she learned during this trip into her daily husbandry and keeper talks at the Smithsonian’s National Zoo.

Meredith, for you, this was a ‘homecoming’ of sorts. What was that like?

Bastian: Returning to Tuanan and visiting the area where the Sungai Lading forest and my base camp once stood was very much a homecoming for me. Seeing the current state of the Sungai Lading area was difficult and very sad to see. However, equally encouraging was to see how much the Tuanan forest has grown over the years.

Pak Nadi, one of the very first field assistants at Tuanan, now operates the site’s boat. Three of my field assistants from Sungai Lading are now working at Tuanan. Seeing them and their families was like returning to my second family.
