I was preparing arthropod traps with my teammates near the town of Tonatico, when suddenly an small bull appeared near us, we continue our work, but the bull didn't move away. The animal just stared at us like saying "stay away from my territory", when we finished our work, to go to another sampling point we had to go through were the bull was. We accomplish this when the guide scared the bull with its own excrement. That was kind of funny.
