On Snares and Poaching

January 30, 2014

As a follow-up to our last post on snared chimpanzees, we are happy to present France24’s documentary featuring the chimpanzees of the Sonso Community, and the ex-hunter program designed to reduce the number of snares in the forest which put our chimpanzees at risk.

Thanks to France24 team for their hard work! Here’s a link to the documentary:

Uganda: Bushmeat Poachers Repent

A Tale of Two Snares

November 28, 2013

This Thanksgiving (for our American & Canadian readers!), BCFS is very thankful for two of our recent snare survivors. Since the start of the project in 1990, there have been 48 snare injuries in Sonso, some of which are permanent injuries, including missing entire limbs; others have luckily lost their snares before serious damage was inflicted. From the start of the Waibira project in 2010, there have been 26 documented snare injuries. BCFS employs a team of snare removers, who patrol both Sonso and Waibira territories for snares. Since the advent of this program, funded by the Oakland Zoo, the snare team has removed hundreds of snares that have been set in the forest to catch game such as bushbuck or duiker.  BCFS also works with the surrounding villages through our “ex-hunters” program, funded by the Arcus Foundation, which aims to reduce local populations’ reliance on the forest for meat by organizing a goat farming scheme. Sadly, our chimpanzees sometimes travel to the greater outskirts of their territory, areas which still run a high risk for snares.

Meet James. He’s 7 years old, the only child of Janie (though he soon will have a baby brother or sister!), and the son of the dominant male Zefa. James is an active little one, often wrestling with his friend Klauce (age 6), or acting like a big, dominant male by drumming on tree trunks. In July of 2013, James got a wire snare on his right hand that restricted his four fingers. He had the snare for several months, but unfortunately lost all fingers, leaving him with a mitten-like hand.

Since losing his fingers, James has slowly been regaining his confidence. He now plays with the other juveniles again, although he struggles to keep up with the group because he must walk while cradling his right hand. We are very happy that James avoided serious infection of his wound. Though he is missing his fingers, the wound has healed, and he will luckily survive.

Our other recent survivor, Kutu, was luckier than James. She is 35 years old, with 4 children: Kato (male, age 20), Kana (female, 15), Kasigwa (male, 10), and Karibu (female, 6). Kato, Kana, and Kasigwa have all had snares. Kana is permanently disfigured on her right hand and left foot, and has recently gotten a third snare on her already snared hand. Given her family’s history of snares, we were very disappointed when Kutu was seen on the far outskirts of Sonso territory in October 2013 with a wire snare around her left wrist. This was particularly worrisome as she has two young children, and is pregnant with a third infant. How would she manage with an injury on her hand? Kutu is one of our most well habituated females, and is very comfortable around human observers. However, on the day she first got her snare, she was extremely nervous to approach us and we were only able to view her snare using the zoom setting on our cameras! The snare seemed to pain her a lot, for she held it close to her chest without putting weight on the hand. From that day we did not see Kutu for several weeks, which was quite worrying as we could not monitor her snare. Luckily when she returned, she was snare-free, and the snare does not appear to have made any permanent damage.

For human observers, snare injuries can be very hard to watch. The chimpanzees are often in obvious pain, and attempt to remove the snare while only making it worse. Intervention by humans is rare, as the chimpanzees must be alone in order to be darted, which is nearly impossible for a young chimpanzee like James, or a mother like Kutu.  We at BCFS remain thankful for the ever-impressive resilience of ‘our’ chimpanzees.

Robert Seyfarth on Language Evolution

Professor Robert Seyfarth, based at the University of Pennsylvania, is renowned for his research (with colleague Dorothy Cheney) on behaviour in non-human primates. Drs. Cheney and Seyfarth are particularly known for their exemplary use of playback experiments in the wild as a means of testing the parameters of vocal communication.

Dr. Seyfarth recently spoke about language evolution at the University of Neuchâtel. Please enjoy this podcast of his talk.

Research Spotlight: Harmony Yersin

BCFS welcomes another Master’s student to the Waibira and Sonso communities: Harmony Yersin, from the University of Neuchâtel. Here is a description of her research:

“The effect of snare injuries on infant care and parasite infection in wild female chimpanzees”

In recent years, human population near habitats where wild chimpanzees live have been increasing. One consequence is the illegal setting of snares hidden in the forests to catch animals. The chimpanzees are not targeted by poachers, but they are sometimes accidentally caught in the snares. Most survive, but they will suffer lifelong consequences. It is estimated that one third of chimpanzees in Budongo Forest, Uganda, suffer from health problems due to snare injuries.

Various studies have already been conducted on the problem of snaring in Budongo Forest. In this study, I will focus on the relation between snare injuries and female reproductive success by focussing on three aspects that have received comparably little attention so far: (a) behavioural differences in infant care of snared and healthy mothers, (b) differences in intestinal parasite load of snared and healthy mothers and (c) predisposition of contracting human diseases.

Welcome Nathalie!

Today we welcome a new student to BCFS. Nathalie Richi is currently conducting master’s research with Dr. Klaus Zuberbühler at Université Neuchâtel in Switzerland. Here is the topic of her thesis:

“Multi-modal communication in male wild chimpanzees, influence of the hierarchy”

For my Master’s Project, I’m looking at the multimodal system of communication between male chimpanzees. Potentially relevant factors within a wild community are the age, sex, and social rank of the signaller, as well as the complexity of the social interactions. I am interested to see if the hierarchy has an effect on the communication between males. My goal is to compare the uni- and multi-modal communication of different males, and the frequency of gestures or vocalizations. The prediction is that the use of different modes of communication will be dependant on their social position within the group.
