At the Sun Bear Sanctuary of BOSF Samboja Lestari, Kalimantan, Indonesia, Windi and Petung have been enjoying the Enclosure D with its 0,67 Ha of forest since January 17th. Windi has hardly been seen since the 17th, she spends all her time inside the enclosure behind the tree cover. Her quest for privacy shows in hindsight how much she must have suffered during the long years spent in her cage, never able to get away from humans into her own space.

I sometimes meet Windi in the dens in the late afternoon when all is quiet and she seems happy and calm. Petung, however, is having a hard time adapting to his new environment. He used to be best buddies with Windi, but now he is very often seen alone, pacing along the fence of the enclosure. I suspect Windi is chasing Petung away, but I don’t know why. I’m waiting a little in the hope that they will sort things out by themselves, before I add another female to the group hoping that a third party will resolve Petung’s issue.

Work on Enclosure E has begun. It will be about 0,7 Ha in size, it has some nice big trees and will be the new home for another 3 bears. The daily rains are considerably slowing down the work in progress, but little by little we’ll finish this one too, and move on to the next enclosure. We still need about 4500 EUR to finish Enclosure E, so any donation is more than welcomed.
