The response of wild primates to potential predators is dependent on the level of threat that is perceived (De A. Moura, 2007; Papworth et al., 2013). Primates often react to the presence of predators with intimidation displays and many species incorporate objects from their environment into their displays (Beck 1980). In capuchin monkeys (Cebus and Sapajus species) displays involving branch shaking and breaking branches to throw or drop on predators are well-documented (Oppenheimer & Oppenheimer, 1973; Beck, 1980; Chevalier-Skolnikoff, 1990; Panger, 1998; Fragaszy et al., 2004). Capuchins have also been recorded banging rocks as an auditory anti-predator display (De A. Moura, 2007) and Boinski et al. (1988) reported a male white-faced capuchin (Cebus capucinus) killing a venomous snake with a branch. Here I report on an observation of an unusual threat display involving fur-rubbing with Citrus sp. leaves by an adult male hooded capuchin (Sapajus cay) in the Upper Paraná Atlantic Forest fragment of Rancho Laguna Blanca in eastern Paraguay.
