Figure 5.7. An adult male long-tailed macaque (a) and lactating female rhesus
macaques (b) in a free-ranging group around Khao Khieow Open Zoo. The male

macaque and intermediate relative tail length between those of long-tailed and rhesus

logical characters between these two species (Malaivijitnond and Hamada,

Figure 5.7
). We previously reported one adult male pig-tailed macaque
approached the group, successfully mated a female long-tailed macaque, but no
hybrid offspring was observed (Malaivijitnond and Hamada,
2008
). However,
during our visit in September 2009, we found the juvenile male showed mixed
morphological characters between the relative tail length (tail length/crown-
rump length × 100) of 120 percent of the long-tailed macaque (Fooden,
1995
)
and a dark brown crown patch of the pig-tailed macaques (Fooden,
1975
).
At Wat Tham Khao Daeng, Nakhon Si Thammarat Province (8° 14'
29” N, 99° 52' 11” E), long-tailed macaques were sympatric with stump-
tailed macaques. The Wat Tham Khao Daeng is located near a limestone
