forest and are occasionally found near human settlements
and temples.

30y. Females have no visual sign of estrus.
Neonates are creamy white.
Locomotion:
Quadrupedal.
Social Structure:
Multimale-mutifemale groups. Matrilineal
hierarchies are very strong. Group size:
5-40. Home range: NA Day range: 400-3000m
(1312-9843ft).
Behavior: Diurnal,
arboreal, and terrestrial. Stump-tailed macaques
travel on the forest floor and along the banks of
streams. They do not swim. The have been
the subject of many captive behavioral studies but few
field studies. After a conflict, they have a
ritual reconciliation behavior in which the subordinate
presents its hindquarters to the dominant, which clasps
the presenter by the rump. The eases the tension
between individuals. Grins, teeth chattering, and
lip-smacking are other signs of submission. The
subordinate may also offer a hand for a mock bite.
The dominant animal may present to a low-ranking
individual to reassure or pacify it. Grooming is a
form of social interaction that promotes appeasement and
group cohesion. These macaques may groom for a few
seconds to more than an hour. In a captive study,
wounded individuals were groomed more than usual.
The dominant male stops female fights and protects
infants. In a captive study, 66% of all social
behavior involved touching and huddling. Some 50%
of the agonistic behavior toward mating pairs was
directed by adult females. The tail position
indicates an individual's intentions: tail down means
submission or fright; tail curled up indicates
excitement; tail straight up is an assertion of
dominance. The teeth-chattering face is a greeting
or appeasement signal. When attacked by a
high-ranking animal, a stump tail may redirect its
aggression by attacking a nearby subordinate. In
Assam these monkeys are feared and reputed to attack
people if they are disturbed.
Mating: Dominant
males copulate with high-ranking females throughout
their estrus cycles. Mating lasts 12-20 minutes,
after which partners remain attached and are often
harassed by other members of the group. Of all the
observed mating, 92% had some form of harassment.
High-ranking males are the most likely to be harassed,
usually by adult females and juvenile males and
females. When low-ranking males mate, they are
often interrupted by the dominant male; to avoid
interruption, they mate while he is mating with another
female. A male can copulate 10 times a day.
Males and females make an orgasm face. A
crescent-shaped vaginal plug is formed by semen.
The male's penis fits lock-and-key with the female's
specialized reproductive tract and may function as a
reproductive isolation method.
Vocalizations: 17
graded calls. The most common vocalization is a
coo used when approaching other group members
to avoid aggression and initiate grooming or other
friendly interactions. Southern China and
