Research Abstract

Japanese macaques have the matrilineal social structure, and the life history of females has been studied more than 50 years. But non-troop males have been scarcely studied because of the difficulty of the pursuit in the wild. The purpose of this study makes clear the life history of males.
Results of this study are as follows : 1)There are two stages in the non-troop males ; troop-following male and non-following male. 2)There are also two stages in the non-following male ; solitary male and male-group male. 3)The ratio of troop male, troop-following male and non-following male is 2:3:3. 4)Young males aged from 4 to 10 years old live in the male-group and old males aged over 15 years old live in solitary. 5)Stable male-group is formed based on males of same age or same generation of the same troop. 6)The highest aged male leaves the male-group and begins to follow the troop movement in breeding season. 7)The lowest aged male of the male-group often returns back to his natal troop. 8)This male takes out younger males of his troop to the male-group, and it is the main mechanism of emigration. 9)The age of male emigration from the natal troop is most frequently from 4 to 6 years old in Kinkazan population. 10)Length of stay in the troop of immigrant males varies from 1 to 8 years. 11)Throughout his life, the male immigrates only one or two other troops.
From these results, it is possible to describe roughly the life history of the male Japanese macaques.
