The BCFS family announces with sorrow the passing of the late Eriku Philipo on May 24, 2014.  His presence at camp will be missed greatly by staff, administration, and students alike.

Philipo, a former employee of Budongo Sawmills, lived on the premises of BCFS where he retained employment as a craftsman making pots, stoves, and other metal tools. He was often sitting outside of his home, offering a cheerful wave and greeting to all passers-by. May his soul be at peace.

While off-grid, on the outskirts of their territory, the Sonso community was startled by the sudden distress calls of a blue duiker. The chimpanzees hastened down the tree at a run and found the duiker, ensnared by its neck in a wire tied between two trees. Although we thought the chimps might strongly react to the duiker – after all, many of the chimpanzees themselves have snare injuries – they all stared at the duiker silently, with their fur pilo-erect, before travelling away.

Field assistants Adue Sam and Gideon Monday remained behind and removed the duiker from the snare after the chimpanzees left. It had sustained minor lacerations and bleeding around the neck, but took off running when released. Thanks to Sam & Monday for preserving one life from illegal poaching! The following week, the BCFS snare patrol team canvassed the area and removed several more snares.

A Birth in Sonso

February 16, 2014

Harriet had a baby girl! Pictured here (in slightly fuzzy video stills) at 1 week and 3 months. She has Harriet’s pug nose! Even at 3 months, she is very vocal and constantly cooing to her mom and siblings.

We name infants according to the first letter of the mother’s name, so in April we’ll be seeking female ‘H’ names for her naming party. Harriet has 4 other children: Hawa (m, 21), Helen (f, 13), Honey (f, 8), and Heri (f, 5).

Chimpanzees have a society in which females leave their natal community around puberty and immigrate to another group. It seems that females ‘try out’ several communities before finding the group where she will stay and bear children.  In Sonso, our immigrant-age females (Anywhere between 12-16 years old) will ‘disappear’ for a few weeks at a time during their fertile oestrus period, and we assume them to be visiting neighboring communities. At the same time, we also occasionally see stranger females who come to visit us, though they don’t always stay. This 2014 dry season, we have already seen 3 stranger females. We’re excited to see whether we’ll have permanent additions from this batch of exploring females!

Last year at this time, Sonso had 3 immigrant sightings, 2 of which remained with our group (below). Both Upesi and Irene became fully habituated after only a year with the Sonso Community. They tend to spend a lot of time grooming together, or with other members of the community, which is nice for us to see. Researchers, Veterinary staff, and Field Assistants all like the two females very much, and grooming is one way chimpanzees build strong affiliations with group members.

Irene

The newest immigrant female to the Sonso community, Irene is a very quiet female with a curious, friendly face. She first came to the community in 2012, and has since often been seen grooming, feeding, and travelling with the community. She was named in 2013 after the daughter of a BCFS employee, and is estimated at 15/16 years old.

Upesi

Named “fast” in Swahili, Upesi is another recent immigrant to the Sonso community. She was first seen in the southeast and regularly joined Sonso when they travelled to that area. She very quickly became comfortable around researchers and chimpanzees alike, and very little time passed before she was well habituated and walking through camp!  She is an estimated 13/14 years old.

Kaija

We all know how quickly kids grow up, but does it ever really cease to shock just how fast they do it?! You may remember our post about Kaija, Kwera’s newborn boy, back in October.

Now at 6 months, Kaija is already incredibly mobile. He’s progressed from clinging to Kwera’s belly to riding on her back, and he is constantly exploring his environment while toddling about unsteadily on two legs, or crawling on all fours. He’s also become more vocally active, graduating from baby coos to joining in on pant-hoots and pant grunting to approaching males.

Despite his impressive development, there are still times where we’re reminded of just how small he still is: when exploring tree climbing on his own, Kaija recently looked shocked to find himself at the height of 3 meters. His whimpers brought a hasty Kwera running to his aide, and she, along with sisters Karibu and Karo, immediately began to groom away his distress.
