Update from our orang-utan partners in Borneo

Share this article

Our partners in Borneo, HUTAN – KOCP, have a dedicated orang-utan research team composed of 10 research officers working in a research site that is home to around 20 wild orang-utans.  HUTAN-KOCP have been studying these orang-utans for the past 15 years.  We're really proud to support the great work that HUTAN-KOCP do and were thrilled to receive this news recently about one of the orang-utans called Jenny.

HUTAN - KOCP

 15 years!!!!    

Growing up wild in the Lower Kinabatangan Wildlife Sanctuary, Sabah, Malaysia

Jenny (below left) is the first wild orang-utan habituated by KOCP in 1998 – She has been followed regularly for the past 15 years.  The orang-utan research team has watched her son Etin, grow up and leave his mother and now observes Jenny raising her daughter Malatus (below right).

Malatus is unusual as she was born while her mother was under observation just over 7 years ago. This past October 3rd was a proud but also bittersweet day for the research team as Malatus spent the night in her own nest away from her mother for the first time.

This is a milestone in orang-utan development indicating the offspring is now full weaned. On the morning of October 4th Jenny came to meet Malatus, so it is likely she knew generally where Malatus was on her first night alone. 

The following night Jenny made her nest and settled in. Malatus was still feeding and then she too started to build her own nest about 10 m away in the next tree. The team then witnessed Jenny peek up over the edge of her nest to take a quick look at her daughter’s nest building skills while Malatus wasn’t watching!

Though Malatus now ranges out of sight from her mother at times she mostly still sleeps very nearby. While males are expected to gradually leave their natal (birth) area female orang-utans tend to settle in adjoining home ranges.

See the resemblance? Like mother like daughter! (Except daughter doesn’t have the beauty spot!) What a difference 7 years makes!
