I’d like to thank everyone for their kind words and thoughts following the death of Bulindi’s oldest and much-loved chimpanzee, Joyce. Her untimely death last week, after she was injured by a farmer’s trap, affected all of us at the Bulindi Chimpanzee & Community Project profoundly.
Ultimately, Joyce’s story is one of resilience and survival. She was, minimally, in her mid- to late-forties when she died – old for a wild chimpanzee – but she might have been in her fifties. In a landscape like Bulindi where chimpanzees must learn to survive in the midst of people, a chimpanzee doesn’t reach such a grand age without being smart and resourceful.
We’ve known Joyce since 2012 when we began monitoring the chimpanzees daily. What changes she must have witnessed in her lifetime! Decades ago, when Joyce was young, her forest home was thick and dark, with an abundance of wild foods. The chimpanzees stayed inside the forest and had little contact with their human neighbours. That all changed over the last 20 years: the big food trees were logged for timber, and the forest was cleared to the river banks and swamps as a swelling human population sought fertile land to plant crops. The chimpanzees lost almost their entire forest home. Now the chimpanzees turned to the village gardens to find food. Besides her forest, Joyce also lost many members of her community, as conflicts with villagers grew and people and chimps were forced to compete with one another.
As one friend commented on hearing news of her passing, “If only Joyce could have sat down with us long before this, to tell us her story. Of her children, her childhood, how things changed as the forest was cut, and yet how she and her community have endured.”
Joyce was a prominent character in Bulindi, always at the heart of the group. Unencumbered by dependent offspring (Joyce last gave birth more than a decade ago), she often led the group, navigating dangerous roads and crossing farmer’s fields, avoiding people as best she could. But she could also be feisty in unwanted encounters with humans. We think she was probably alpha female in her former years (for an earlier post about Joyce’s bravery). Despite having no reason to trust humans, in recent years Joyce became especially trusting of our research team, satisfied that we meant no harm to her or her family.
In her last year, Joyce’s eye-sight deteriorated; probably this contributed to her failure to spot the trap (though traps are usually concealed by vegetation). She became less active, spending long hours of the day napping in comfy nests. This is how her long life should have passed: quietly and in comfort. The cruel circumstance of her death was undeserved and unfair. Many villagers in this region live in poverty and depend on farming for their livelihoods. Crop losses to animals can be devastating for farmers. Still, the vast majority of villagers agree that using ‘man-traps’ to protect crops is wrong, especially given the known danger to chimpanzees (sadly, Joyce is the latest of several chimpanzees known to have died from traps at Bulindi).
Although she’s gone, Joyce’s legacy will live on in Bulindi. Genetic analyses by Dr Maureen McCarthy and Jack Lester (of the Max Planck Institute for Evolutionary Anthropology, Germany) revealed that Joyce is almost certainly the mother of Bulindi’s long-term alpha male, Sylvester, who has sired many infants in the community. The Bulindi Chimpanzee & Community Project is now more committed than ever to ensuring the survival of Joyce’s children and grandchildren in Bulindi. And we’ll work closely with villagers and conservation partners to raise awareness about the dangers of traps – which are illegal in Uganda, as well in inhumane – in the hope that no more chimpanzees have to suffer.
Thank you to Dr Joshua Rukundo (Chimpanzee Sanctuary and Wildlife Conservation Trust) and Dr Caroline Asiimwe (Budongo Conservation Field Station) and their teams for their effort to help us find and treat Joyce; and a special thank you to the Bulindi Chimpanzee & Community Project field staff and researchers for all they did to help Joyce in the last week of her life: Dr Marie Cibot, Georgia Lorenti, Tom Sabiiti, Jacqueline Rohen, Moses Ssemahunge, Vincent Kiiza, Lorien, Benjamin Hintz and Alastair Bigger.
It's a very sad day for us and the Bulindi chimpanzees. The community's oldest matriach Joyce, who we estimated to be in her mid to late forties, has died.
Sadly, the tragic circumstances of her death, following an injury from a farmer's trap, underscore the threats facing chimpanzees in this region and strengthen our resolve to help them survive.
Chimpanzees are long-lived animals and mature slowly. One of the joys of following their lives over many years is watching youngsters grow up.
We first identified Moses (pictured) in 2012 when he was still a juvenile. Six years later, he's developed into a handsome young adult, albeit still with some growing up to do.
The Bulindi Chimpanzee & Community Project strives to help villagers coexist with chimpanzees where people and chimps share landscapes outside of protected areas. We hope we'll be able to see many other young chimps grow into adulthood in the years to come.
Meet little Kasatu - the last of the 22 chimpanzees in our 'meet and greet the Bulindi chimps' series. Kasatu, meaning 'the third' in the local Runyoro language, was so-called because he was the third infant born during a baby boom in April last year. He is Jemima's first infant and she's hugely protective of him. Perhaps because Jemima herself is small, Kasatu is the smallest of the three same-aged infants. Still, he's doing well and likes to clamber around by himself, whenever Jemima lets him out of reach. Kasatu has a 'crazy old man' face which exudes character.
