Due to their inconspicuous behaviour and colouration, it has been assumed that titi monkeys' main anti-predator behaviour is passive crypsis and hiding. So far, active predator mobbing has been documented only for black-fronted titi monkeys, . Here we report for the first time mobbing behaviour of red titi monkeys, (previously ), as reaction to an ocelot () and a . We also report other active anti-predator behaviours, such as alarm calling and approaching, as reactions to tayras () and raptors. Our observations provide additional evidence for sex differences in anti-predator behaviour, possibly related to the evolution and maintenance of social monogamy.
由于伶猴行为不显眼且颜色不易察觉，人们一直认为伶猴主要的反捕食行为是被动隐匿和躲藏。到目前为止，仅记录到黑额伶猴有主动驱赶捕食者的行为。在此，我们首次报告红伶猴（之前的 ）对一只豹猫（ ）和一只 做出反应时的驱赶行为。我们还报告了其他主动的反捕食行为，如对南美獭（ ）和猛禽做出反应时的警报呼叫和靠近行为。我们的观察为反捕食行为中的性别差异提供了额外证据，这可能与社会一夫一妻制的进化和维持有关。
