Precautions Ensure that trap doors are fitted with good, protected safety catches. Ensure that traps are in sound condition before use. Avoid attempts to restrain captured primates physically. Adult male baboons not caught in traps may attempt to defend trapped members of the troop. Handlers should always be armed and ready to scare off any aggressive males.
Collapsible traps are useful if primates are captured on a regular basis.
Good safety catches are essential. If the capture is part of a control operation, use as many traps as possible - preferably as many as the number of animals to be caught, but not less than a third of that number. The technique described here was developed by M.E. Keith. Observe the troop and determine its size, composition, and habits. This will allow you to estimate the number of traps that are needed and to get an idea of the wariness of the animals.
