Inter-troop Interaction
Our two study groups, White Island (W Troop) and Camp (C Troop), occasionally encountered neighboring groups (X and Z), which were not habituated to humans and typically fled at our approach. Over the course of my three years in the field, I observed only a single direct interaction between W and C Troops. This occurred when C Troop made an incursion onto White Island after the floodwaters had receded. Following a brief confrontation (photos below), C Troop retreated.
