Bornean White Bearded Gibbon, Tanjung Puting National Park, IndonesiaSometimes they let you get close. And when they do, why not take advantage. This was a very friendly Bornean white-bearded gibbon that I met in Indonesia. He hung around the welcome center of Tanjung Puting National Park and was obviously very accustomed to people.
