Monkeys are trapped in St. Kitts and Nevis using a longstanding trapping tradition. Trappers use a technique originally developed by a local man, Mr. Joseph Cabey, in the 1970s to assist the biomedical research facilities in humane trapping.
Trappers can trap the entire group as long as the trapper traps the least dominant animals first, as the dominant animals lead group movements. To trap the entire group, the trapper therefore waits until the least dominant group comes in, trapping in essentially reverse fashion, finally getting the dominant animals trapped at the end. This process can take a few days.
