Primates spend half of their lives at sleeping sites and should select them carefully. Macaques usually use about thirtysleeping sites and their selection respond primarily to predation avoidance. We studied a northern pigtailed macaques troopsleeping sites selection pattern in a degraded forest fragment, the Sakaerat Biosphere Reserve in Thailand. We identified107 sleeping sites with only 15 reused sites selected at random. Using resource selection function, we found that macaquessleeping site selection is best explained by proximity to feeding areas. Preliminary study of habitat characteristic suggeststhat there is no structural difference between selected and available sleeping trees in the troop home range. In degradedhabitat where forest structure does not offer optimal sleeping trees against predators and with scattered fruit treedistribution, macaques seem to favor strategy based on food resources proximity. These results highlight impact of habitatdegradation may have on sleeping site selection in a flexible species.
