The Moor macaque occurs in southwestern Sulawesi. It is mainly fruit-eating and also eats leaves and arthropods.
Its body fur is brown to dark brown, with a pale brownish-grey patch of fur on the rump.
In South Sulawesi, Indonesia, researchers walked 29 line transects covering 57 km in total, repeating each transect on two consecutive days. The survey effort was 114 km across six sites. They estimated moor-macaque density and encounter rates, then compared the records with open areas and hunting traps. The landscape included forest, farmland, grassland, and karst terrain.
Macaques were encountered less often in clearings without forest and where wire-loop traps were present, and more often where there were more people and domestic animals. Comparisons with earlier surveys showed lower encounter rates at at least two sites. The study-wide density estimate was 24 individuals per km², below the 1992 estimate of 36.1, but the confidence intervals overlapped.
An extinction-risk assessment has not been added yet.
Encounter rates had fallen at at least two sites compared with earlier surveys, and were lower in open clearings and where wire-loop traps were found. The authors called for further surveys across South Sulawesi to determine whether regional patterns reflect a broader change.
