Abstract
Two troops of grey langur monkeys (Presbytis entellus entellus) were observed in the Gir Forest, western India for approximately 220 hours in two of three seasons at very high crude densities ranging from 115–128 langurs per km2. Daily activity patterns and home range use are described and a scan-sampling technique of activity distribution employed. Food and predator avoidance are estimated to be major determinants of population density and home range size, structure, and composition.
