Self-anointing behaviour in captive titi monkeys ( spp.).

Self-anointing behaviour using  sp. was reported in two captive titi monkeys ( and ). The study was carried out from October 2013 to May 2014 during an experimental study investigating the gut passage time of these individuals at the Getúlio Vargas Zoobotanical Park, north-eastern Brazil. Although leaves, petioles and flowers of contain chemical substances that could affect the presence of ectoparasites, it is unclear if titi monkeys demonstrate self-anointing behaviour as a method of self-medication. However, due to the presence of large glands in and chests, and the high frequency of occurrence observed for the adult male, we cautiously suggest that the use of may be linked to olfactory communication.
