by different ecological niches, long-tailed macaques live in a warmer climate
(south of 18° N) and rhesus macaques live in a colder climate (north of 18° N)
(Fooden,
1982
). During our survey, the relative tail length of monkeys in this
troop was noted and varied between 60-100 percent. The pelage color pattern
in some monkeys was a bipartite pattern of rhesus macaques (Hamada
et al
.,
2006
; Malaivijitnond
et al
.,
2007b
). Some monkeys had crests at the crown as
long-tailed macaques or posteriorly directed crown hairs like rhesus macaques
or a dark brown crown patch like pig-tailed macaques.
We also observed a free-ranging troop of macaques at the Khao Khieow Open
Zoo, Chon Buri Province (13° 12' 56” N, 101° 03' 19” E) with morphological
