在猕猴物种中，成年雄性日本猕猴最不可能进行雄性关怀（即成年雄性和未成熟的猕猴之间的亲密互动，包括抱着、携带和梳理毛发）；然而，他们也会照顾婴儿，尽管很少。我们检查了17例首次观察到的男性护理时，未成熟的年龄小于1岁。在30年的观察期内，31只成年雄性中有11只作为中心雄性进行雄性护理。他们的年龄和优势等级对男性照顾的发生没有影响。大多数病例首次记录于交配季节末和出生季节初（1 - 3月）之间，而在交配季节（10 - 12月）很少观察到雄性护理。在17例中，有12例在第一次观察后6个月内停止了男性护理，而在其余病例中，持续了至少1年。在17例中，有15例男性倾向于照顾低等级母亲的无亲缘关系的女婴。在某些情况下，雄性和婴儿母亲在雄性护理开始之前和之后的6个月里都表现出梳理毛发的互动，而在其他情况下，这种梳理毛发的互动在雄性护理开始之前和之后都没有记录。我们还研究了一些关于雄性不成熟关联的假设，以及雄性和婴儿可能通过雄性照顾获得的好处。
Among theMacacaspecies, adult male Japanese macaques are the least likely to perform male care (i.e., affiliative interactions between adult males and immatures, including holding, carrying, and grooming); however, they perform male care for infants, albeit infrequently. We examined 17 cases of male care observed for the first time when the immature was younger than 1 year of age. Eleven of the 31 adult males who remained as central males during the 30-year observation period performed male care. Their age and dominance rank did not influence the occurrence of male care. Most cases were first recorded between the last part of the mating season and the first part of the birth season (January–March), whereas male care was rarely observed during the mating season (October–December). In 12 of the 17 cases, male care ceased within 6 months after the first observation, whereas in the remaining cases, it continued for at least 1 year. In 15 of the 17 cases, males tended to perform male care for matrilineally unrelated female infants of low-ranking mothers. In some cases, the male and infant mother showed grooming interactions for 6 months both before and after the start of male care, whereas such grooming interactions were never recorded either before or after the start of male care in other cases. We also examined some hypotheses on male–immature associations and the probable benefits that males and infants might acquire through male care.
