Columbian black spider monkey, Chester had a quick health MOT during a routine implant check.
The six-year-old primate is to become DZG’s breeding male so vet Peter Stewart pictured above with keeper Nicola Wright sedated Chester to ensure a previous contraceptive implant was no longer present.
Senior Curator, Derek Grove, said: “Fortunately, Chester’s implant had already dissolved, but while he was sedated we were able to give him a full body and dental check, as well as taking blood samples and weighing him, without causing him any additional stress at a later date.”
Chester and older brother, Charlie pictured below arrived last month from Colchester Zoo and have joined Evita and Valentine to form a breeding group.
Columbian black spider monkeys are Critically Endangered on the IUCN Red Data list and are part of an international conservation programme at DZG.
