Jakie (|1996). She is the darling of Bukit Lawang and always in need of love from the guides and tourists, because of her past. Born in the wild in Gunung Leuser National Park, her mother got sick when Jackey was only 2 years. She was fed and raised by rangers and volunteers for years and got accustomed to humans. Ever since her reintegration back into the jungle, she has always kept her affection to humans. Jakie is the mother of 4 children: Darma (|2005), Jodie (|2009), Jeniper (|2015) and Johny (|2019), who is still with Jakie.

Mina (|1979). She has suffered in her childhood in captivity. Despite being taken well care of in a rehabilitation center since her 4th, she has never overcome her fear towards humans and therefore she can at times be aggressive. Nevertheless, she has had a successful life after her reintegration, giving birth to 4 offsprings: Thomas (|1991), Juni (|1998), Cetrine (|2008) & Masjur (|2014). As a proud (grand-)mother, she still looks after her family and therefore sometimes shows signs of aggression towards people that get too close to her.

Ucok Baba (|1982). Afraid from tigers, Ucok Baba is always high in the trees. The only exception he makes when there are people as he feels protected by humans. While born wild, he has become semi-wild because he has been fed by visitors and lost his fear towards humans.

While its kindness towards humans is touching, it is sad that he has become semi-wild and that some visitors or guides feed orangutans for a nice picture or for a better tip, resp. At Local Guides it is prohibited to feed orangutans. Instead we educate visitors about the dangers of feeding or touching orangutans.

Pesek (|1988). While she has had a difficult childhood in captivity, she has been very happy ever since she arrived in the rehabilitation center in Bukit Lawang. Now she is a semi-wild orangutan that loves people. She is currently raising her daughter Palentino Rosi (2013) and is therefore more defensive than usual, which is normal behaviour for a mother. As children usually stay with their mother for ±6 years, Palenfino Rosi is not expected to stay much longer with her. She is also the mother of 4 grown up and wild orangutans: April (|1997), Hirim (|2001), Alam (|2003) an Wati (|2006).

Gay Couple. This wild, gay couple lives deep into Gunung Leuser National Park. Although they also mate with females, deep into the jungle it is not always easy to find other orangutans. So when there is no female around, they just have sex with each other. Locals jokingly refer to this practicle couple with the song “No Women, No Cry”.

Loud Couple. This couple is wild and lives deep into the Gunung Leuser National Park. They are the exception to the usually solitary behaviour that orangutans are known for. When they have sex, they can be very loud and make similar sounds as when humans have sex. And just like humans, they want privacy during their intimate moments together, but their panting and loud screams of excitement can give their location away to curious visitors who quietly witness their performance from a distance behind the trees.
