Size matters! The largest wild stump-tailed macaque Macaca arctoides troop ever reported, located in the Hollongapar Gibbon Sanctuary, northeastern India
Very large and stable, socially coherent primate groups, not including fission-fusion societies, are usually rare innature, owing to constraints imposed by various ecological and social factors. Moreover, unlike species in openhabitats, those in forests tend to have smaller groups, and this becomes further accentuated in small and fragmentedforest patches. We report here an unusually large troop of stump-tailed macaques Macaca arctoides from theHollongapar Gibbon Sanctuary, a small and isolated lowland tropical rainforest patch in the Upper BrahmaputraValley of northeastern India – this is possibly the largest wild group of the species recorded anywhere across itsdistribution range. We hypothesise the potential factors driving the formation of such a large social group of thisvulnerable cercopithecine primate and discuss the conservation implications of this phenomenon.
