It’s been a long time since we last updated you on the progress of the troop of baboons released last December. This has partly been because of personnel changes at the project, but also because the team have been enduring a tough time of late, and all available time has had to go into intense monitoring efforts.
Sadly, since the last blog from the release team, at which point the troop were adapting well to their new life in the wild, we have lost several individuals from Jack’s troop. Chris and Najinga were found dead just near their sleeping sites, presumed to have been killed by leopard. In addition, three other individuals (Nina, Ali & Bob John) have also disappeared from Jack’s troop, and have not been sighted among Zenus’ troop, the wild baboon troop in the area. Jack, Brenda, Becky and Ruth have not been seen since May 11th, leaving their whereabouts a mystery, though it is hoped they have simply moved to another area of the park, beyond the range of the monitoring team’s equipment.
Following such disruption to Jack’s troop, only Mandy could be found with Eddie, who had sustained a very deep flesh wound on his back right leg. After consultation with the Wildlife Centre’s vet it was decided that Eddie would have great difficulty surviving in the wild if his wound were left unattended. On June 6th both Eddie and Mandy were removed from the field and brought back to the Wildlife Centre where they are currently residing. Eddie’s wound needed proper treatment in a closed environment and Mandy was extremely vulnerable on her own without any troop members for protection.
The research team’s efforts to relocate the missing members of Jack’s troop continue.
On a more positive note, the Centre began its second release of rescued and rehabilitated monkeys. In late May, Titan’s troop of fifteen vervet monkeys was released into Kasungu National Park, 13km from the baboon release site. Some monkeys raced for the door, springing out of the cages as soon as the gate was lifted. Others were a bit shy, taking their time to venture out into the great expanse of the wild. Within half an hour of the release all monkeys were exploring their new surroundings, ecstatic to be free!
One of the troop’s adult males, named Jimmy, decided to join a wild baboon troop just two days after the release. Jimmy was the alpha male (leader) of the troop until three months before the release, when another male, Titan, took over the leadership position. Understandably, Jimmy has been having a difficult time relating to his group members… let’s face it, it’s embarrassing to be overthrown and lose all your power… how will the ladies ever respect him now? I suspect Jimmy became a little confused about what species he was on release and approached the baboon troop out of desperation to join another troop. Two weeks later though, he was back with his own kind, no doubt still resentful of Titan.
One of the troop’s adult females, Hellena, went off with a wild troop of vervets in the third week of the release. Just six days later, she was back under Titan’s command – presumably missing all the delicious food we were providing for Titan’s troop. During the first eight weeks of each release we provide the monkeys with supplementary food to help ease their transition into their new environment, allowing them time to learn how to cope with finding all of their own food.
Tragically, Michael, one of the sub-adult males in Titan’s troop was found dead a few weeks after release. He was killed by a predator in the park, likely believed to have been a jackal. Michael was the most curious monkey in the group – one of the favourites of the research team. His playful manner and sweet face made it impossible not to love him. Since his death, his best friend, Moses, has been a bit lost without him. Moses can now frequently be found sitting somewhere near the vehicle or research team, intently watching the humans, as if he’s expecting us to tell him how to continue on.
This event is deeply discouraging for everyone here in the field, especially on the tails of the results from the release of Jack’s troop. The research team and Wildlife Centre staff are currently doing all they can to assess what factors are contributing to the deaths, reworking our release protocol so we all can see increases in survival rates. It is expected that a few individuals will die with every release; however, this does not make it any easier to cope with when we find one of our beloved monkeys dead. We will remember Michael fondly.
All other members of the troop are doing well, and continue to enjoy their new found freedom.
